Lowrie was forced out of Sunday's game in Cleveland after just one inning because of the injury, and he said Tuesday afternoon, "It's still a little stiff, but better mobility."
The infielder's status remains day to day, but he didn't rule out being available off the bench Tuesday, noting, "I think it just depends on the situation."
Lowrie is more likely to be utilized off the bench as a left-handed hitter, if at all, since more discomfort ensues when he's batting from the right side.
He took part in pregame on-field activities "to tolerance," he said, and likened the injury to what he experienced in April last year, when he missed just one game after incurring a neck strain while sleeping.
