Shay Whitcomb is still on San Francisco's 40-man roster on Opening Day 2027.
Christian Koss makes more starts at third base for the Giants over the rest of the 2026 regular season than any other player.
San Francisco placed Willy Adames (left elbow sprain on the transaction log; MLB.com reported an MRI showing a moderate strain of the non-throwing elbow, and the two wordings are recorded here as published rather than blended) and Victor Bericoto (right knee bone bruise) on the 10-day injured list on August 24 and JT Brubaker (bruised ribs) on the 15-day, all three hurt in Sunday's 5-4 loss at Boston. Bryce Eldridge went on the bereavement list and Matt Wilkinson was optioned. The Giants recalled five men from Triple-A Sacramento the same day: Nate Furman, Grant McCray, Anthony Molina, Ryan Walker and Shay Whitcomb. Adames had started 121 games at shortstop and played 1,046.1 innings there; MLB's active-roster page now lists no shortstop among the 26. Christian Koss, a third baseman with 71 innings at short this year and two innings pitched, played the position Monday while Whitcomb made his Giants debut at third. San Francisco won 5-0 behind six pitchers after losing starter Carson Whisenhunt in the third inning to left elbow pain. Whisenhunt was scheduled for an MRI on Tuesday morning and no result has been published. The Giants have used 58 players this season, tied with the Angels and the Athletics for fifth-most in the majors against a league median of 52, and seven of them made their San Francisco debut in August.

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.
