Keegan Akin underwent Tommy John surgery on Wednesday, the Orioles announced.

A really tough break for Akin, who will be a free agent for the first time at season’s end. He might be back down the stretch next year if his rehab goes well. The 31-year-old had a 5.68 ERA in 25 1/3 innings this season. He has a lifetime 4.55 ERA in 393 1/3 innings, all for the Orioles.
