Giants outfielder Mike Yastrzemski left the team’s game against the Mariners on Thursday for what was then an undisclosed reason. It turns out he’s dealing with a tight right calf, Kerry Crowley of the Bay Area News Group was among those to report.
There’s no word on the severity of Yastrzemski’s injury. However, calf troubles have been known to lead to IL stints (the Yankees’ Aaron Judge is among those capable of attesting to that), which would be a difficult late-season development for the Giants. They surprisingly entered play Thursday with a 24-24 record and a playoff spot in the National League, and their success has come thanks in no small part to Yastrzemski. The 30-year-old has been one of the NL’s most valuable players thus far, slashing .285/.391/.553 with nine home runs and 2.3 fWAR in 209 plate appearances.
As a tremendous offensive player who can line up all over the outfielder, Yastrzemski has been the Giants’ MVP, so there wouldn’t be a realistic way to replace him if he does need to go on the IL. They subbed in Luis Basabe on Thursday, but he has just two MLB plate appearances to his name.
