DENVER -- Outfielder Carlos Quentin left Sunday's game against the Rockies in the fourth inning after he tweaked his right groin.
"He's sore. It's day to day. We're hoping this is somewhat similar to Seth Smith's [groin strain in April]," said Padres manager Bud Black.
Smith suffered a groin strain in April, though it wasn't considered serious and he missed four starts and was then eased back into the lineup.
Quentin -- who hit a two-run home run on Saturday in a victory over the Rockies -- had a single in the first inning on Sunday and then felt some pain in the groin area as he went first-to-third base on Jedd Gyorko's double.
Two innings later, and with runners on first and second base and no outs, Quentin hit a ball that turned into a 5-4-3 triple play, even though he beat the return throw to first base. The Rockies were awarded a triple play anyway after Smith was called for interference as he slide into second base.
Quentin eventually left the game as part of a double-switch in the bottom of the fourth.
He missed the first 39 games of the season after suffering a bone bruise to his left knee in a Spring Training game in March. He returned on May 13 and has four hits in his first 12 at-bats over five games since then.
The Padres have an off-day Monday before opening a two-game series against the Twins at Petco Park on Tuesday. There will likely be more information made available about Quentin then.
