Bonine tried throwing one more pitch and found himself catching his breath. That's when head athletic trainer Kevin Rand and manager Jim Leyland went to the mound.
"I threw a pitch and it kind of knotted up on me," Bonine said. "I've never cramped up underneath my rib before, so I don't really know what that was. I just cramped up and I just needed to take a big breath, and I was fine. I tried to catch my breath and they came out."
Tests conducted after he left the mound showed nothing worse. Bonine will likely rest for a day or two, but that would've been expected anyway after throwing three-plus innings and 49 pitches of relief.
Bonine's relief prevented what could have been a procession of relievers once Justin Verlander left with nobody out in the sixth. Bonine gave up a two-run homer to Jhonny Peralta upon arrival and a solo homer to Shin-Soo Choo, but then recorded five straight groundouts.
Phil Coke replaced Bonine with a full count and gave up a single to Marson, but got a lunging catch by Brandon Inge on Asdrubal Cabrera's sharp liner before induced an inning-ending double play from Michael Brantley.
