Marsh was removed in the bottom of the eighth inning of Sunday's contest against the Cardinals due to a right hamstring strain, Matt Gelb of The Athletic reports. He went 1-for-3 with a walk and a run scored prior to exiting the game.
Marsh recorded a single off reliever Andrew Kittredge to open the bottom of the eighth, but he left the game after advancing to second base on a hit by Nick Castellanos. The outfielder will likely undergo additional testing on his leg, and a trip to the injured list could be on the table.
