Perdomo was removed during the fifth inning of Monday's game against the Rockies for an undisclosed reason, Jack Sommers of SI.com reports.
It's not yet clear if Perdomo left with an injury, though it would be a bit odd to pull him at this stage in the game to get him off his feet, even with a 7-0 lead. The team could provide more information about the shortstop's removal after the game.
