"If it was a night game," said Lowrie, "it probably would've had time to loosen up, but it's just so stiff right now that we want to make sure it doesn't get worse. This is the first time I've ever woken up like this, and I knew right away. Even driving in, I couldn't turn my head to check the other lanes."
Manager Bob Melvin was going to do his best to refrain from using the infielder on Sunday.
"With an injury like that, you'd like to rest him, but you never know how it plays out," Melvin said. "He's the only other infielder on the bench, so if something were to happen to someone else, you'd see him out there."
Lowrie, batting .344 on the season, was confident he'd be back in the starting lineup for Monday's series opener vs. the Angels.
