Written about him

The four days

A Rainout In Atlanta In June Left The Giants Needing Two Starters On Saturday

San Francisco's schedule from Friday to Monday asks for four starting pitchers. Blade Tidwell is the only one named. Saturday is a split doubleheader at Oracle Park, moved off Sunday on June 23 to clear a travel day for the makeup of a June 18 rainout in Atlanta, which is now Monday. Ten men have started a game for the Giants in 2026; Robbie Ray and Tyler Mahle were traded, Trevor McDonald and Carson Whisenhunt are on the 60-day injured list, Adrian Houser went on the 15-day list Wednesday, JT Brubaker is on the 15-day list, and Matt Wilkinson was optioned to Sacramento on August 24. That leaves Logan Webb, Landen Roupp and Blade Tidwell, and all three are already spoken for. The club is carrying thirteen pitchers, which is the most the rules allow before September 1, when the active roster goes to 28 and the pitcher limit to 14. The doubleheader lets it add a 27th man for one day, and that exception is the only way Wilkinson pitches in the majors before September 8. Two takes filed, on the 27th man and on the length of the four starts.

Carson Whisenhunt's Only Scoreless Start This Season Was The One He Did Not Finish

San Francisco placed Carson Whisenhunt on the 15-day injured list on Tuesday and recalled Spencer Bivens from Triple-A Sacramento. Whisenhunt made eight starts this season, 34.2 innings at a 6.49 earned run average, and Monday's was the only one in which nobody scored on him. He is the third San Francisco starting pitcher this year to lose an elbow: Hayden Birdsong went on the 60-day injured list in March with Tommy John surgery already named in the transaction, Trevor McDonald had his on August 5, and Whisenhunt has been told to have his. Adrian Houser then left Tuesday's game after 26 pitches with what Tony Vitello called tightness in his flexor, and has an MRI Wednesday morning with no result published. Whisenhunt's major league record is 13 starts, 58 innings, 33 walks and 42 strikeouts.

Ten Pitchers Have Started A Game For The Giants This Season, And Three Of Them Cannot Start Another

San Francisco has played 127 games and used ten starting pitchers, tied for the sixth-fewest in the majors against a league median of thirteen. Three of those ten are unavailable: Tyler Mahle was traded to Atlanta on August 2, Robbie Ray to San Diego on August 3, and Trevor McDonald has been on the injured list since July 21 with a strained right elbow. Between them they made 53 of the 127 starts and threw 287.2 of the club's 677 starting innings. Seven pitchers covered the first 111 games; seven have covered the sixteen since the deadline, three of them names that had never started a major league game for the Giants. Boston has named Jake Bennett for Sunday and San Francisco has named nobody.

San Francisco Claimed A Third Baseman Thursday. The Roster Spot Came From An Elbow.

San Francisco claimed Shay Whitcomb off waivers from Houston on Thursday and optioned him to Triple-A Sacramento, opening the roster spot by transferring Trevor McDonald to the 60-day injured list. Nothing about McDonald's elbow changed Thursday. It was rebuilt on August 5. The transfer was a piece of paperwork the club had been able to file for eight days and filed the moment it wanted something.

The Giants Cannot Trade A Meniscus

Casey Schmitt tore the meniscus in his left knee, Trevor McDonald is having his elbow rebuilt, and Harrison Bader's foot got worse. A seller converts what it is willing to lose. None of this was ever for sale.
