The problem for Viciedo came playing defense, as the soreness made him unable to move his thumb to close the glove. On Monday, Viciedo moved his tightly wrapped thumb without much of a problem.
This injury took place in the first inning of last Monday's contest against the Yankees, when Viciedo dove for a Robinson Cano single. Viciedo was able to get up and throw Cano out at second, but left the game in the bottom of the first. He didn't play Tuesday, Game 1 on Friday, Saturday or Sunday.
Viciedo is hitless over his last 12 at-bats, but he is batting .286 over his last 15 games.
