Rest-of-Season Projections

Could play utility role in 2025
Koss is an option to slide into the outfield and could operate in a utility role this season, Shayna Rubin of the San Francisco Chronicle reports.
ANALYSIS
Koss earned a spot on the 40-man roster after a successful Cactus League campaign. The 27-year-old shortstop finished with a .341/.426/.512 slash line in 41 plate appearances as a non-roster invitee. "He's another guy I watched this spring who carried himself with such confidence," president of baseball operations Buster Posey said Thursday. "At shortstop, third -- wherever he was playing. To me, he's the epitome of a baseball player." Koss didn't suit up for the Giants on Opening Day, though the first game he gets into will mark his MLB debut after several years in the minors.

Candidate for utility role
Koss has a chance to win a utility role with the Giants this spring, the San Francisco Chronicle reports. He started at shortstop and went 1-for-3 in Saturday's spring game. "He's continuing to impress, and he hit a ball down the line for a double and he's playing with a lot of confidence," said manager Bob Melvin. "We're giving him some reps right now. It's nice to see because we're putting an emphasis on defense and he's played great defense every place we've put him."
