Detroit Tigers right-hander Matt Manning didn't look comfortable after throwing his 80th pitch with one out in the seventh inning Friday against the Houston Astros. Catcher Jake Rogers trotted to the mound, and shortstop Javier Báez signaled to the dugout.
Moments later, manager A.J. Hinch and assistant athletic trainer Christopher McDonald emerged from the dugout to investigate.
Manning tweaked his lower back on his second-to-last pitch in the seventh inning Friday, but as of Saturday afternoon, the Tigers haven't placed him on the injured list. That could change in the coming days following a brief wait-and-see period from the Tigers' medical department.
