With Alex Rodriguez set to exclusively serve as the designated hitter in '16, New York was in need of a reserve third baseman behind starter Chase Headley, and it appears Castro will fill that void. The 25-year-old infielder was acquired in a trade with the Cubs early last month in exchange for Adam Warren and Brendan Ryan.
Castro has never played third base at the Major League level. In six seasons with the Cubs, he primarily played shortstop (841 games) and made 33 appearances at second, where he'll likely see the majority of his time with New York.
Castro, a three-time All-Star, batted .265/.296/.375 with 11 homers and 69 RBIs through 151 games with the Cubs last season.
