The fourth overall pick throws his first professional inning

Jackson Flora threw one inning on September 4, and it was the most-waited-for inning in the organization. The fourth overall pick signed in July, spent eight weeks not appearing in a box score anywhere, got assigned to Low-A San Jose on September 1, and three days later faced five hitters: one hit, one walk, two strikeouts, no runs. There is nothing to evaluate in one inning and nothing worth inventing around it. What there is: a college arm that threw a full season got a controlled look before the calendar ran out, which as recently as last Tuesday looked like it was not going to happen at all.

A correction, and it is a load-bearing one. Ramon Marquez, the arm the Giants got back for Luis Arraez, has been credited in this space with six High-A starts of thirty innings, eleven hits and a 0.67 WHIP. Those starts were thrown for Jersey Shore, Philadelphia's High-A club, before the trade. As a Giant he has made two starts, both in August, ten innings, nine hits, six earned runs, and he has been on Eugene's seven-day injured list since August 25. He is still a twenty-year-old with 105 strikeouts in sixty-nine innings and he still ranks eighth, because a strikeout does not change teams when the pitcher does. But the Giants have watched ten innings of him, not forty, and forty innings of a pitcher is a different amount of information than ten.

The best week belonged to the eighteen-year-old, again. Josuar Gonzalez went four for four on September 1 and homered on September 5, and his Low-A line reads .357/.444/.566 with six doubles, six triples and thirteen steals in thirty-one games. Behind him: Scott Bandura drew six walks in six games at Triple-A and moves up to 11, Keyner Martinez threw his third straight start of one earned run or fewer and jumps eight spots to 14, Joe Whitman threw eight innings without a walk, and Trent Harris has now gone eight consecutive appearances without allowing a run. The bill came due elsewhere. Jesus Rodriguez's season ended on the sixty-day list with elbow neuritis, Luis De La Torre walked five more and fell to 19 with eighty-two on the year, and three of the top ten are still on affiliate injured lists with nothing named on any of them.

Seven walks in seven games, and four of his seven hits were doubles. No home runs, which is the only reason this is a .882 week instead of a loud one, and it is also the least interesting fact in the row. A twenty-one-year-old drawing a walk a game in September against pitchers who have a book on him is the version of this rookie season worth watching, because the power was never the question. He is at .265/.359/.451 through ninety-nine games with fifty-four walks, and the on-base percentage has gone up every month he has been here.

Two singles in sixteen at bats, one walk, and five games in a seven-day stretch, which is what a corner outfielder gets in September when the roster has expanded and the club wants looks at other people. The season line has slipped to .231/.319/.369 across 118 games. That is a fourth outfielder's line, and the front office does not have to decide anything about it until November, which is roughly the kindest thing that can be said this week.

Here is the whole story of his major league season in one number: he has three extra-base hits, all of them doubles, and two of the three came in this one week. Six hits in seventeen at bats is his best week in the majors, and it also raised his slugging percentage from .231 to .269, which tells you how flat the other forty-one games were. He is catching every day because Daniel Susac and Jesus Rodriguez are both on the sixty-day list, and that is settled through October now.

The injury has a name now: a right knee bone bruise, per the club's transaction log, which placed him on the ten-day list on August 24. A knee bruise on a corner bat in the last week of August is a season-ender by arithmetic rather than by severity. No games since August 23, and the line stays at .244/.253/.419 with four home runs and one walk in eighty-six at bats. One walk. There is a whole offseason of hitting coaching in that number.

Twenty days since his last game, which was August 18. The rehab assignment that began August 13 is still open in the league's records, the twenty-day clock for a position player ran out on September 2, and there is no transaction on either side of that date. A rehab assignment that stops producing games and then quietly outlives its own deadline is usually a setback nobody has written down yet. The plain version: the Giants traded for a hurt infielder at the deadline and he has been hurt the whole time since.

Sixty-day list, fractured left patella, last game August 9. Nothing has changed and nothing will before spring. The fifty-three-game line is .243/.289/.375 with eight walks, and a catcher who loses the last six weeks of his first real major league season loses more than the plate appearances; he loses the part where he learns the pitching staff.

Placed on the sixty-day injured list on September 4 with right elbow neuritis, per the club's transaction log. Season over. The rehab assignment produced one game on August 23 and then nothing for twelve days, which was the tell, and the diagnosis has caught up to it. Neuritis in a catcher's throwing arm is a nerve problem rather than a structural one, which is better news for 2027 than a ligament would have been, and it is still six weeks of a twenty-four-year-old's development gone.

Five innings, two hits, two earned runs on September 3, and five walks, which is the number that keeps this from being a good start. He has now walked eighteen in forty-two and two thirds major league innings and thirty-five in seventy-two at Triple-A, so the walk rate is not a September wobble; it is the pitcher. The stuff has always been fine. Fourteen appearances at a 4.43 ERA is roughly what a fifth starter looks like, and the club has three more weeks to decide whether that is what it has.

Sixty-day list, left elbow sprain, last pitched August 24. Season over. The eight-start major league line closes at 6.49 with twenty-one walks in thirty-four and two thirds innings, and the Triple-A line above it, thirty-eight walks in eighty-two innings, says the command went before the elbow did. Whether those two facts are related is the question the winter has to answer.

Four more scoreless appearances, and counted off the dates rather than off last week's sentence, the streak is eight in a row and nine innings, every outing since August 23. His only three earned runs of consequence came in one third of an inning on August 8, in his first week in the majors, and the two since then are single runs on August 14 and August 21. Twenty-one strikeouts in fifteen innings. A twenty-seven-year-old reliever nobody had a plan for in April has pitched his way onto next year's roster conversation, which is the most reliable thing the minor leagues produce and the thing prospect lists are worst at seeing coming.

Three innings, five hits, four earned on September 4, one week after six innings of two-run ball, and the major league ERA goes from 4.63 to 6.14 on a single afternoon, which is what four starts does to an ERA. The good news survives it: four walks in fourteen and two thirds innings. He is twenty-three, he has thrown forty-three Double-A innings this year at a 1.87 ERA, and a bad September start is the cheapest tuition in baseball.

One hit in eleven at bats, and thirty major league at bats on the season, which between them prove nothing at all and would not prove anything if he had gone eight for eleven either. The Triple-A line is the real one: .293/.377/.414 in 102 games with fifty-two walks against fifty-five strikeouts. He is a bench infielder getting bench infielder playing time in September, and the thing to watch is whether the club gives him a real look in the last three weeks.

Five innings out of the bullpen on September 4, four hits, three earned, and two strikeouts against two walks, which is a duller outing than his debut and still a useful one: he gave the club five innings it did not have to get from anybody else. Nine and two thirds major league innings is his whole career, which is the label to keep on it. Five strikeouts in those innings from a pitcher who struck out seventy-two in sixty-four at Double-A is the gap worth watching.

Five innings, one hit, no runs, six strikeouts on September 5, and the line as a Giant is now fourteen and a third innings, eight hits, two walks, thirteen strikeouts, a 1.88 ERA and a 0.70 WHIP. His Atlanta innings are shown separately because they were a different pitcher in a different role and lumping them together flatters nobody. Tyler Mahle is gone and this is what came back, and five weeks in it looks like the best return of the deadline.

Sixty-day list, right elbow strain, last pitched July 20. Seven weeks now. Fourteen major league starts and seventy innings from a twenty-five-year-old is a real season even ending like this, and he is one of three arms on this page whose 2026 finished on an elbow.

He opened the window four for four on September 1 and homered on September 5, and the Low-A line is now .357/.444/.566 across thirty-one games. The counting stats are the strange part: six doubles, six triples and three home runs at San Jose, which is a teenager who hits the ball hard and then runs, plus thirteen steals. Twenty-one walks against thirty strikeouts at eighteen years old in a league where he is the youngest regular. San Jose plays through September 11, so there are a handful of games left in the best age-relative season anybody in this organization has had.

A homer and a double on September 1, then a normal week around it, which after last week's five-for-twenty-five is exactly the correction that was owed. He is at .302/.363/.473 in sixty-nine High-A games as a nineteen-year-old, eighteen home runs across two levels, and the strikeout rate has crept up since the promotion without ever becoming a problem. Eugene plays through September 13. He will finish the year with a full season at a level most players reach at twenty-two.

Third straight week on San Jose's seven-day injured list per the league's roster entry, with no injury named at the source and no game since August 20. San Jose plays through September 11, so there is a theoretical return and no reason to expect one. The Low-A sample closes at twenty games: .231/.276/.319 with twenty-nine strikeouts and six walks. It reads badly and it is a seventeen-year-old who was promoted straight past the complex level in July, so it should read badly. The ACL line above it, .298/.382/.535 in fifty-four games, is the season.

One professional inning, which is one more than he had a week ago, and his Last 7 row is his entire career. One hit, one walk, two strikeouts, five batters faced on September 4. There is nothing to evaluate here, and pretending otherwise would do him no favors. What matters is that the fourth overall pick got on a mound in a real game before the season ended, which as recently as last Tuesday looked unlikely. He holds at 4 on draft position and scouting reports, the same two things that put him there in July.

Four innings and ten hits on September 5, which is a worse start than his Double-A debut and a different kind of bad: the debut was five walks and eight strikeouts, this was one walk and two strikeouts and hard contact all night. Two Double-A starts now read nine innings, fourteen hits, nine earned runs. Nobody should move a twenty-one-year-old off a ninety-eight-inning High-A season at a 2.92 ERA with 118 strikeouts on the strength of nine innings in September, so he holds at 5. It is still worth writing down that the level has hit him twice.

Two home runs in six games, both in a two-day stretch on September 4 and 5, and the season total across two levels is twenty-eight. The Sacramento line is .289/.372/.506 in forty-five games, which is the same shape as his Double-A line, which is the point: he did not lose anything on the jump. Rosters expanded a week ago and he is still in Sacramento while three pitchers went up ahead of him. The forty-man decision in November was settled in July. The September call-up apparently was not.

Placed on Richmond's seven-day injured list on August 25, per the club's transaction log, with no injury named and no reinstatement posted. Last game August 22, which is seventeen days. Richmond plays through September 18, so a return would still mean something, and a seven-day list that has run seventeen days usually is not seven days. The Double-A line holds at .308/.356/.467 in thirty-one games and remains the best evidence in the system that a college infielder can skip a level without noticing.

A correction, and it matters. The six High-A starts of thirty innings, eleven hits and a 0.67 WHIP widely credited to Eugene were thrown for Jersey Shore, Philadelphia's High-A club, between June 19 and August 1. As a Giant he has made two starts, on August 11 and August 19: ten innings, nine hits, six earned runs. The rows above are now labeled by the uniform he was wearing. None of this makes him a worse prospect, because sixty-nine innings with 105 strikeouts at twenty is the same season no matter whose logo is on the jersey, and he holds at 8. It does mean the Giants have seen ten innings of him, not forty. He went on Eugene's seven-day injured list on August 25 and has not pitched since.

Six games, five hits, two doubles, three walks and six strikeouts, which is a normal week and after a thirty-four-day absence a normal week is the good outcome. A correction to last week's entry, which said no transaction was ever posted: Richmond activated him from its seven-day injured list on August 28, and the record was there. The Double-A line is .270/.352/.413 across seventeen games with eight walks, and the strikeouts, eighteen in sixty-three at bats, are the thing that follows him up every level.

Five shutout innings on September 1, three hits, one walk, four strikeouts, and it is comfortably the best start he has made as a Giant. It also arrived one week after two innings and five earned runs, which is why he is still at 10 rather than back up: five Eugene starts read 4.57 and one of them being excellent does not make the other four disappear. But the shape was right for the first time since the trade, and there is one more Eugene turn left in the schedule to repeat it.

Scott Bandura has now had four straight weeks worth writing about: six for twenty-two with six walks and a home run, a .993 OPS, and a Triple-A season that reads .318/.399/.489 with nine home runs and twenty-three steals across ninety games. He is twenty-five and that is the ceiling problem, but a .399 on-base percentage at Sacramento is not a fluke by September and he moves up three to 11. The two arms move further: Keyner Martinez jumps eight spots to 14 on three consecutive starts of one earned run or fewer, fifteen and two thirds innings with one earned run and twenty strikeouts, which has dragged a 5.42 ERA down to 4.61 since the middle of August; and Joe Whitman goes 21 to 16 on eight innings, six hits, one earned run and no walks at Triple-A on September 2, his third straight start of two earned runs or fewer. Going the other way, Luis De La Torre drops eight to 19, and the number is eighty-two walks in a hundred and two thirds innings. He struck out five on September 6 and he has 126 strikeouts on the season, so the arm is real; a pitcher who walks nearly a batter an inning at High-A at twenty-three is a reliever with a decision to make, and the ranking now says so. Parks Harber falls five to 20 on a second straight cold week, eleven strikeouts in twenty-one at bats.

Two promotions came out of the back half of the board, which almost never happens twice in one week. Marty Gair went from Eugene to Richmond on September 1 on the strength of twenty-one strikeouts in eight High-A innings, and Double-A answered with four earned runs in two innings; he moves up three to 28 for the promotion and not for the outings. Logan Martin went from Richmond to Sacramento and threw two and a third hitless innings on September 5 with three walks, which is a fair summary of his year, and he moves to 31. Robert Hipwell is the merit move, six spots to 30: five for fourteen with a triple and a .900 week, and a season line of .210 with eight home runs and forty-one walks that remains the strangest thing on this page. Kaeden Kent jumps eight to 32 on a second healthy week since the ankle, five for twenty with two steals, which is exactly the boring evidence that was missing for seven weeks. Two absences got answered, both of them corrections to last week: Jakob Christian was on Eugene's seven-day injured list the whole time and was activated on September 6, and Tyler Switalski went on the seven-day list on August 18 and was moved to the sixty-day list three days after that, which ends his season. Both were flagged here as unexplained. Both had transactions on file.

Four seasons are now over on the sixty-day list, and Jesus Rodriguez makes three of them catchers or pitchers the club was counting on in September. Against that, three long absences got explanations this week rather than guesses: Bericoto has a named injury, Christian and Switalski both turn out to have had roster entries on file the whole time, and Jordan was activated on a transaction that existed. Three of those four are corrections to last week, and they are here in full rather than quietly fixed. The one still open is Mayer, whose rehab clock ran out six days ago in silence.

San Jose plays through September 11, Eugene through September 13, Richmond through September 18 and Sacramento through September 20, so there are two more editions of this with live games in them and then a winter of arguing. What the argument will be about: whether an eighteen-year-old hitting .357 at Low-A and a nineteen-year-old hitting .302 at High-A should open next season two levels apart or one; whether the best arm in the system is a twenty-year-old with ten Giants innings or a twenty-one-year-old who just got hit around twice at Double-A; and how many of the seven names currently on injured lists come back as the same players. Back next Tuesday.

Stats sourced from the MLB Stats API for September 1 to September 7, 2026, the seven completed days ending yesterday, which abuts last week's window exactly. Injured-list statuses are read from the league's per-player roster entries and the clubs' transaction logs; where the source names no injury, none is named here. Rate stats in the Last 7 rows are recomputed from summed game logs, not averaged; innings pitched are converted from the API's decimal notation before any ERA or WHIP arithmetic. Streak and drought claims in the prose are counted from game-log dates rather than carried over from the previous edition. Player ages pulled live from the Stats API. Jackson Flora's Last 7 row is his entire professional career and is labeled as a small sample. Ramon Marquez's and Henry Lalane's rows are split by the uniform each line was compiled in; Marquez's High-A line was corrected this week after the team labels were checked against his game log, and Marcelo Mayer's major league line was compiled with Boston. Anthony Molina's major league line is shown as two rows, Atlanta and San Francisco, for the same reason. The ACL Giants finished their season July 23 and the DSL clubs finished August 17, which is why several Deep Cuts and Joniel Hernandez carry final lines.
