"We have more options -- we were carrying three outfielders for a while there," Yankees manager Joe Girardi said. "Carlos was the fourth, and then we were running infielders out there.
"But with Martin, who's played a lot of outfield, and then having [Ichiro Suzuki], too -- we'll make sure he's ready when he goes out there."
Ichiro had been seeing regular duty in right field, but Prado's acquisition is expected to bump Ichiro back to a reserve role. Girardi said that could help the 40-year-old veteran from a physical standpoint.
"I think at this point in the season, you kind of go day by day. But we acquired Prado to play a lot," Girardi said. "We'll go day by day [with Ichiro]."
