BOSTON -- Orioles shortstop J.J. Hardy was not in Monday's lineup vs. the Red Sox after exiting Sunday night's game with a right hamstring strain suffered while running the bases in the fifth inning.
"It's way too early to tell," manager Buck Showalter said on Hardy's condition. "Day to day. About what you'd expect. Everybody's sore.
"I'm not going to broadcast whether he's available or not today. Hopefully, we got it before it turned into something that would be a problem. We'll see."
Without Hardy, who might not have played with the quick turnaround anyway, the Orioles had Ryan Flaherty at shortstop, with Jonathan Schoop back at third base and Steve Lombardozzi at second. Both Flaherty and Schoop were charged with errors in Sunday's 6-5 loss, and the O's are cautiously optimistic Hardy will be ready for the Toronto series that starts Tuesday night.
Hardy missed six games with back spasms earlier this year, and he said Sunday's injury came out of nowhere, though his hamstrings had been tight as a result of the back issue.
