The Rangers announced, via press release, that they have claimed outfielder Alex Castellanos off waivers from the Red Sox.
The 27-year-old Castellanos is a former 10th round pick that will be joining his fourth organization following this move. Originally selected by the Cardinals in the 2008 draft, he was traded to the Dodgers in exchange for Rafael Furcal in July 2011 before being flipped to the Red Sox earlier this year in exchange for fellow outfielder Jeremy Hazelbaker. Boston designated Castellanos for assignment upon re-signing Mike Napoli.
Castellanos has batted just .171/.186/.390 in 43 big league plate appearances (all with the Dodgers), but he has been a force in the minor leagues. The Florida native is a career .291/.382/.525 hitter with 36 homers and 35 stolen bases in 848 Triple-A plate appearances.
The Rangers' 40-man roster previously had just 39 players, so the claim of Castellanos brings them to a full 40 players.
