Diamondbacks pitcher Taijuan Walker has a partially torn ulnar collateral ligament and will need to undergo Tommy John surgery according to manager Torey Lovullo, Nick Piecoro of azcentral reports.
Walker, 25, gave up five runs on 15 hits and five walks with nine strikeouts over 13 innings to start the season. His 2018 season is done and he will likely miss most of the first half of the 2019 season as well.
That’s more unfortunate injury news for the Diamondbacks. Fellow starter Shelby Miller is on the mend from Tommy John surgery as well, while Jake Lamb and Steven Souza have been out with injuries of their own.
The Athletic’s James Fegan reports that the White Sox are shutting down starter Lucas Giolito for the remainder of a season. An MRI revealed a mild lat strain, which typically comes with a three- to four-week recovery timetable. The third-place, 65-84 White Sox have nothing left to play for, so it makes sense to play it safe with their prized young hurler.
Giolito, 25, had a breakout season. He went 14-9 with a 3.41 ERA and a 228/57 K/BB ratio in 176 2/3 innings. He made his first All-Star team and will likely earn a few downballot votes for the AL Cy Young Award.
Giolito was scheduled to start Tuesday’s series opener against the Twins. Ross Detwiler will start in his place opposite Martín Pérez.
