WEEI's Gerry Callahan must be bummed. The guy the Red Sox got back when Callahan-favorite Jeremy Hazelbaker was dealt (Alex Castellanos) was claimed off waivers by the Texas Rangers. Castellanos came to the Carmine Hose in an unheralded October trade that sent Halezbaker to the Dodgers. So, basically, Boston ends up with nothing in the transaction—as Castellanos could have provided organizational depth at AAA for the infield and the outfield. Oh, well. Win some, lose some. By the way, Castellanos had two brief cups of coffee with the Dodgers in 2012 (16 games) and 2013 (8 games). Come to think of it, they were more like two small cups of espresso.
