BOSTON -- The Pirates claimed Oscar Tejeda, who's played both infield and outfield, off waivers from the Red Sox and assigned him to Double-A Altoona. Tejeda, 22, was designated for assignment when the Sox needed 40-man roster space following the Kevin Youkilis trade on Sunday.
To make room for Tejeda on Pittsburgh's 40-man roster, left-hander Doug Slaten was designated for assignment.
Tejeda, who's young and offensively capable, was MLB.com's No. 13 Red Sox prospect at the start of the 2012 season. He hit .262 (53-for-202) with 15 doubles, five home runs and 31 RBIs for Double-A Portland.
