"I think the middle of our infield could be really good with the two guys we have, and I think Starlin is going to do a really good job," manager Joe Girardi said.
Castro tallied 991 hits over six seasons with the Cubs, so the Yankees are not overly concerned about the 25-year-old's bat. Their curiosity is in how Castro will adjust to second base, where he played 33 games down the stretch last season.
If Castro's flashy play in the third inning serves as any indication, the Yanks' pitchers could be in for a treat.
With Mike Aviles at the plate, Castro ranged up the middle, cutting behind shortstop Didi Gregorius to flag a ricochet off pitcher Tyler Cloyd's glove.
