OAKLAND -- Yankees right fielder Nick Swisher exited Friday's 3-2 loss to the A's after feeling his upper left leg grab at him running to first-base on a seventh-inning groundout.
The Yankees announced Swisher's injury as a mild left hip flexor strain, but he said it felt more like his quad was bothering him. He's day to day.
"It's more low. It's more my quad than it is anything," Swisher said in the visiting clubhouse at the Coliseum. "We're going to see exactly what happens tomorrow and we'll let you guys know from there."
Swisher dealt with a left hamstring strain from late April to early May and was bothered by his left and right groin in Spring Training. Those injuries are seemingly unrelated.
Swisher was trying to bust it out of the box on his grounder to third with the Yankees down, 2-0, in the seventh.
"Just tried to turn on that extra gear, went to go grab it and it grabbed something else," Swisher said. "I hate getting busted up like this, but we got to do what we gotta do to get back on the field."
Swisher was 0-for-3 with two strikeouts against A's left-hander Tommy Milone when he was removed.
The Yankees found out on Thursday that Brett Gardner is likely lost for the season and have been dealing with a seemingly high number of injuries this season. Asked about the disabled list, Swisher said "it's not in my vocabulary."
Swisher also had a right hip flexor strain in 2008.
