Athletics pitcher Chris Bassitt will undergo season-ending Tommy John surgery on Friday, MLB.com’s Jane Lee reports. He was diagnosed with a partially torn ulnar collateral ligament over the weekend, so this news doesn’t come as much of a surprise.
Bassitt, 27, is certainly out for the remainder of the 2016 season and will likely miss a sizable portion of the 2017 season as well. The right-hander made five starts for the A’s to begin the season, but put up an ugly 6.11 ERA with a 23/14 K/BB ratio in 28 innings.
Jesse Hahn took Bassitt’s spot in the Athletics’ starting rotation. Hahn is expected to start next on Saturday versus the Orioles.
