Castro is only 25 years old but already has quite the resume. He is a three time all star, and was the National League hit leader in 2011.
Castro is under team control through 2019 making him a long term Second Base solution for the Yanks.
After spending his entire career at shortstop Castro made the switch to Second Base late last season to make room for young Addison Russell at Shortstop. He batted .353 in 38 games after making the switch to second base.
The Yankees had the third worst production in the majors from their second basemen a year ago, and have had several names fill the position since the departure of Robinson Cano after the 2013 season. Those names include Brian Roberts and Stephen Drew both who just could not produce enough for the Yankees while in the Bronx.
With Castro the Yankees have a stabilized their second base hole and even have some depth at the position with Dustin Ackley who hit very well after coming to the Bronx at the trade deadline last season, and prospect Rob Refsnyder who showed he can hit big league pitching, but is still working on his game in the field.
