"It just tightened up on me," Jennings said. "It should be good."
When asked if he can play Friday, Jennings replied: "We'll see tomorrow. Just tightened up. See how it goes."
Jennings played center field in the top of the third, but he was lifted for pinch-hitter Nick Franklin in the bottom half of the frame.
With the bases loaded and two outs, Franklin blooped a double into left and three baserunners scored.
