SEATTLE -- Mariners reliever Stephen Pryor left Tuesday's 5-4 loss to the Padres in the ninth inning after experiencing tightness in his left groin and will undergo an MRI exam on Wednesday.
With one out in the ninth, the Padres' Everth Cabrera hit a ground ball that first baseman Justin Smoak fielded and tossed to the rookie reliever, who was running to cover the bag. Pryor pulled up before reaching the base. The right-hander exited without attempting to throw another pitch.
"Just kind of tightened up doing the normal run over to first, something that happens, but don't think it's too serious," he said.
Pryor is 1-0 with five strikeouts, three walks and a 1.69 ERA in six appearances since being called up from Triple-A Tacoma on June 1.
