Injury Notes: Bailey, Cobb, Moore, Holland, Wieters, Iwakuma, Hanley

As expected, Reds starter Homer Bailey underwent Tommy John surgery today, as MLB.com’s Mark Sheldon reports. Though his previously-repaired flexor mass tendon apepared in good shape, Bailey’s UCL was determined to be completely torn, leaving little in the way of options to avoid surgery.

• Likewise, Rays righty Alex Cobb was found to have a fully torn UCL, as Marc Topkin of the Tampa Bay Times reports, meaning he too was virtually assured to require a TJ procedure. Cobb says the best-case scenario would have him return late in 2016. Fellow Tampa hurler Matt Moore has continued to build his way back from his own UCL replacement, with MLB.com’s Bill Chastain reporting that Moore was able to throw all of his pitches in a live BP session. Moore says he is targeting a mid-June return to the big league bump.
• Though his shoulder has shown some evidence of progress, Rangers lefty Derek Holland will wait an additional two weeks before he begins throwing, as Jeff Wilson of the Fort Worth Star-Telegram tweets. Though Texas has enjoyed a somewhat surprising contribution from its starting staff (3.71 ERA, 9th in baseball), peripherals suggest that some regression is forthcoming. Regardless, Holland’s health is critical to the club, both this year and — perhaps even more so — in the future.
• Orioles catcher Matt Wieters is set to catch seven innings tomorrow as he continues to work fully back from Tommy John surgery, Roch Kubatko of MASNsports.com tweets. Wieters’ ability to return to health and productivity will go a long way toward determining his free agent earning power next winter, of course. It will also tell on Baltimore’s ability to compete for a postseason slot, though replacement Caleb Joseph has been a revelation.
• The Mariners appear unlikely to see righty Hisashi Iwakuma return until early June, at the soonest, per Bob Dutton of the Tacoma News Tribune. Manager Lloyd McClendon says that Iwakuma is “probably still two to three weeks from going out [on a rehab assignment]” and will then need to throw a few outings before making it back to the big leagues. As with Wieters, Iwakuma needs to get healthy and show that he can continue to be effective in order to bolster his open market case. The scuffling Mariners, meanwhile, are not only firmly in need of his services, but also must assess whether they will be in the market for rotation help over the summer.
• Red Sox outfielder Hanley Ramirez is not likely to need a DL stint for his left shoulder sprain, manager John Farrell tells Peter Abraham of the Boston Globe (Twitter link). Boston seems to have dodged a bullet with the injury situation, as the club can ill afford an extended absence from the player who has paced the club in hitting thus far.
