Diamondbacks right-hander Bronson Arroyo recently resumed throwing after he was diagnosed with a sprained ulnar collateral ligament in his right elbow last month, but he told Steve Gilbert of MLB.com late this afternoon that he will undergo season-ending Tommy John surgery.
With pitchers going down left and right this year, we really shouldn’t be surprised by another pitcher headed for Tommy John surgery at this point, but it’s still striking given Arroyo’s well-documented durability. The 37-year-old averaged 211 innings per season from 2005-2013 and threw at least 199 innings in all of them. He posted a 4.08 ERA in 14 starts with the Diamondbacks prior to landing on the DL for the first time in his career last month. It turns out he made six of them with a torn UCL.
Tommy John surgery typically carries a timetable of around 12 months, so Arroyo figures to be sidelined through midseason next year. He’s owed $9.5 million in 2015 while his contract includes an $11 million club option for 2016 or a $4.5 million buyout.
Bad news for the Cubs’ Yu Darvish: The right-hander is headed back to the disabled list with right triceps tendinitis, the team announced Saturday. It’s the second such assignment for Darvish this season, but the first time he’s been sidelined with arm issues. Neither the severity of his injury nor a concrete timeframe for his recovery has been revealed yet, but the move is retroactive to May 23 and will allow him to come off the DL by June 2, assuming all goes well.
Prior to the injury, Darvish went 1-3 in eight starts with a 4.95 ERA, 4.7 BB/9 and 11.0 SO/9 through 40 innings. Needless to say, these aren’t the kind of results the Cubs were hoping to see after inking the righty to a six-year, $126 million contract back in February, though the circumstances affecting his performances appear to have largely been out of his control. He missed a start in early May after coming down with the flu and has struggled to pitch beyond the fifth inning in five of his eight starts to date.
The Cubs recalled left-hander Randy Rosario from Triple-A Iowa in a corresponding move. Rosario has yet to amass more than five career innings in the majors, but has impressed at Triple-A so far this year: he maintained an 0.97 ERA, 2.8 BB/9 and 6.1 SO/9 through 19 1/3 innings in 2018. As for Darvish’s next scheduled turn in the rotation, Tyler Chatwood is lined up to take the mound when the Cubs face off against the Giants in the series finale on Sunday. A starter for Monday night’s game has yet to be determined.
