Crews has dealt with a minor injury that has kept him out of the Double-A Harrisburg lineup since April 17, and he was held out of Tuesday's game as a precaution due to rainy weather, Mark Zuckerman of MASNSports.com reports.
Crews is presumably dealing with some sort of lower-body injury if the rainy weather played a role in him not playing Tuesday. The 22-year-old outfielder is slashing .244/.326/.415 with two home runs and two steals in 10 games this season.
