One of the reasons the San Francisco Giants have liked Christian Koss so much is his baseball savvy. Against one of the team’s top 2026 tormentors, the Diamondbacks, Koss’ baserunning helped fuel a rare win against Arizona.
Hit by a pitch in the fifth, Koss dashed from first to third on Nate Furman’s sacrifice bunt, realizing third baseman Jose Fernandez hadn’t retired fast enough to the bag. That set up Drew Gilbert’s sacrifice fly to take a 2-1 lead, helping starter Landen Roupp snap his five-game losing streak. The Giants are now 2-8 against the Diamondbacks this season.

Jung Hoo Lee hasn’t started two games in a row because of a bruised right elbow, but he pinch hit in the eighth Thursday and drew a 10-pitch walk. He scored on Bryce Eldridge’s double and rookie outfielders Jonah Cox and Turner Hill provided RBI singles that inning, while third baseman Shay Whitcomb sent Cox in with a safety-squeeze bunt.
With Willy Adames likely out for the rest of the season with an elbow injury, Koss has started 27 of the past 28 games and has a plus-2 outs above average (OAA), an advanced Statcast metric. Adames, who has played through back issues this season, had a minus-17, tied for worst in the majors.
The Giants have Marcelo Mayer, acquired from Boston at the deadline, waiting in the wings. When he’s ready to come off the injured list – he expects to be out of a walking boot for a bruised foot soon – Koss is likely to shift back to third, where he has also played well.

Gilbert has gotten onto a tear and he’s looking comfortable in the leadoff spot, going 10-for-24 three homers in eight games including Thursday’s home run to right-center in the first inning. Gilbert has also improved defensively after a bit of a slow start; he’s now at a plus-3 OAA and his arm and range are both in the top 20%.
With little else at stake, the Giants are gauging how all of their young players and bench guys might fit in next year. Gilbert played for manager Tony Vitello at Tennessee, and has done nothing but solidify his standing. Koss, Cox and Hill have also made good impressions.

Roupp, now the team’s No. 2 starter, has had his wobbles, but Thursday, he allowed only one run, a homer by catcher Gabriel Moreno, who studded a changeup on the ninth pitch of his at-bat in the fourth. Roupp went five innings but he walked only two batters after he’d walked 19 over his previous five starts and had a 6.20 ERA in that stretch.
Rookie reliever Trent Harris also helped his cause after he worked two scoreless innings, adding to his allowing just one run in his past six outings while striking out 12 in 8 â…“ innings. Carson Seymour is also getting more looks out of the bullpen; his scoreless inning Thursday means he’s allowed just one run over his past 9 â…“ innings.
