Philadelphia Phillies catcher Carlos Ruiz completed his 25-game suspension for a positive drug test and was activated form the restricted list on Sunday.
Ruiz, 34, had tested positive for an amphetamine after a career year in 2012 when he hit .325 with 16 home runs and 68 RBI in 114 games.
He was in the lineup and batted fifth on Sunday for the Phillies' game against the New York Mets.
To make room for Ruiz on the 25-man roster, the Phillies designated catcher Humberto Quintero for assignment. Quintero had played in seven games and hit .250 with two RBI. He shared time behind the plate with Erik Kratz while Ruiz served his suspension.
"We need him back," Phillies manager Charlie Manuel said of Ruiz. "We're going to get better when he's back."
