The Giants provided updates on a pair of injured minor leaguers on Tuesday (via Evan Webeck of The California Post). Infielder Christian Koss has a broken left wrist and outfielder Grant McCray fractured the hamate bone in his left hand/wrist. McCray is undergoing surgery on Thursday, while Koss will be reevaluated in two weeks.
Koss and McCray both occupy spots on the 40-man roster. They’re two of San Francisco’s four position players on optional assignment. Outfielder Will Brennan and rookie catcher Jesús Rodríguez, both of whom were just sent down, are the only healthy options. The Koss injury explains why the Giants selected Buddy Kennedy yesterday when they wanted an extra infielder off the bench.
McCray was optioned to begin the season and has spent the entire year with Triple-A Sacramento. He’s hitting .237/.360/.370 with four home runs across 211 plate appearances. McCray appeared in 59 big league contests between 2024-25 as a depth outfielder, batting .185 while striking out 67 times in 156 trips.
Koss spent the first six-plus weeks on Tony Vitello’s bench. He only tallied 15 plate appearances over 10 games before being optioned in mid-May. Koss suffered the injury after three Triple-A games. He hit .264/.309/.368 over 76 games as a rookie in 2025. San Francisco could place either player on the 60-day injured list if they need to open a spot on the 40-man roster.

I swear I’ve heard about more hamate bone fractures this season than the past 10 seasons or so.
The Big Hamate Medicine lobby is out of control.
They say you don’t even need it.
It’s fine we’re doing great!
They could outright both these guys off the roster and nobody would know – clean up the 40 man and inject some youth – for the love of ⚾️🤯
They would lose at least 1 likely McCray – With their luck anyone they lose turns out to put up big numbers on other teams. Giants development and player evaluation is the pits. When Tidrow died they just have not recovered.
McCray is not putting up numbers anywhere. His ceiling is a 4th Outfielder on a non contender at best.
Please. Can you do us a favour and cry quietly.
Well, you’re selling Christian Koss short. He’s a good pesky hitter, good in the clutch and is an excellent glove. He’s proven that at the Major League level.
McCray, unfortunately, is probably on the way out due to his extreme swing and miss despite all the tools to be a great player.
The Panda perfected the Hamate IL about 15 years ago. He now teaches seminars on it.
I thought Pablo ate a ham. Now I understand. Kidding aside, Pablo was great for the Giants.
Big breaking new for a team that is so boring and sad to watch I’d rather watch amateur golf leagues on mute.
Kiss would be up if he wasn’t injured
