Detroit Tigers left-hander Tyler Alexander has felt elbow pain for the past month.
Although Alexander felt healthy enough to pitch, the 27-year-old wasn't in perfect shape for any of his four starts this season. He changed his mechanics to ease some of the stress on his elbow.
"Eventually, I just wasn't able to pronate," Alexander said Wednesday. "That was my biggest issue. Throwing a changeup and anything arm side was starting to get pretty painful."
The Tigers placed Alexander on the 15-day injured list Monday, retroactive to Saturday, with a left elbow sprain.
