Jordan Romano left Tuesday night's All-Star Game because of back tightness.

The Toronto Blue Jays closer entered in the seventh inning and tossed just five pitches before he was relieved by Michael Lorenzen.

"He threw his last pitch in the bullpen before he went out there, he just felt a little tightness in his lower back, and we got to take every precaution to take care of these players," American League manager Dusty Baker said. "We hope that it's nothing."
