Philadelphia Phillies catcher Carlos Ruiz left Sunday's game against the Cincinnati Reds in the second inning with a strained right hamstring, the team announced.
Ruiz appeared hobbled after taking off from first base on an attempted hit-and-run play, then came up limping while heading into third after a single by Freddy Galvis.
He was replaced by Erik Kratz, who filled in for Ruiz during his 25-game suspension to begin the season for a positive 2012 amphetamines test.
The Phillies could call veteran Humberto Quintero, who served as Kratz's backup while Ruiz sat out, up from Triple-A if Ruiz is placed on the disabled list -- which is likely the case for strained hamstrings.
The 34-year-old Ruiz, a free agent after this season, snapped a nine-game hitting streak that had raised his batting average to .240.
