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.

EDGE 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.
