Nationals pitching prospect Danny Rosenbaum had Tommy John surgery to repair a torn ulnar collateral ligament on Thursday, a source told

Rosenbaum, 26, will now begin a 12 to 18 month recovery process to return from the procedure. The lefty starter made four appearances this season with the Triple-A Syracuse Chiefs before suffering the injury.

Rosenbaum went 1-1 with a 4.50 ERA in those games with the Chiefs. The former 22nd round pick also appeared with the Nationals in major league spring training, going 0-1 with a 2.70 ERA in three outings.

The Nationals drafted Rosenbaum out of Xavier University in 2009. In six minor league seasons he holds a 3.12 ERA across 121 total games.

    So weird… I find myself actually licking my chops, when I hear of a young pitcher having this done… Thinking that in a couple of years, we’ll find out what kind of pitcher he REALLY is… That’s so sick, I know, BAD UnkyD!!! But it’s just become so commonplace, and so many seem not to suffer any diminution, as a result…. But of course, I wouldn’t wish major surgery on anyone… Especially fam… Be well, Danny! Get better, and do everything they tell you to. Looking forward to seeing you in the Big Rotation, in a couple of years….

      Well, it’s one thing when the pitcher is a prospect at the age of 18 (Giolito) or barely 22 (Strasburg). But for a guy who is 26, now figuring that he’s not going to be back on the comeback trail until he’s 27 or 28? That’s devastating. He’s losing his prime years to the surgery. Very sad.

    National’s elbow as Luke Erickson calls it. It did seem like the eventual conclusion after all the second and third opinions.

    Sadly, the same may occur for the highly touted lefty Felipe Rivero who started out up in Harrisburg.

    And Robbie Ray is starting for the Tigers … before Doug Fister has thrown a single pitch.

    The good news is that Matt Purke’s arm may finally be coming around in Harrisburg. His previous start
    looked very promising in that he only allowed 2 hits over 6 innings and no runs.

      There has been something wrong with him for over a year. I’m actually relieved to hear it was the elbow and not the shoulder.

    Lots of trouble in Atlanta. Heyward, BJ Upton and Uggla are all under-achieving and their fanbase just are in a frenzy. Chris Johnson isn’t near his production from last year and they depend on Freddie Freeman to carry them.

    The Miami Marlins have figured out how to defend Freddie Freeman.

      No way Chris Johnson was going to repeat last season’s performance. Heyward, I can see underachieving, but BJ and Uggs are right in line with their previous trend. FF is great, wish he was a Nat.

      I hope their 2014 mirrors our 2013.

        Our 2013 is too good for the likes of them. To balance your hope, I hope they mirror last year’s Astros record.

    I saw Rosenbaum pitch in Richmond in 2011 when he was still lights out. His fastball did not reach 90, but he had such an off-speed assortment that the opponents were flailing.

    In 2012 he seemed to lose his mojo. His ERA soared and you had to wonder whether he had reached his ceiling, or whether he was hurt.

    I hope he hasn’t been trying to tough out an injury for awhile.

    Peric, how do you think the Nats will fare in your California stomping grounds?

    I don’t mean to be rude, but TJ surgery almost seems to be a 50/50 chance for any hard thrower these days, so at least Rosenbaum gets his done when his ML service time clock isn’t ticking…

    • therealjohnc - May 9, 2014 at 10:06 AM

      Well, TJ surgery is much better than a 50/50 crap shoot these days … but … Rosenbaum is not a kid anymore, was never a hard thrower, and was only a marginal prospect at best. A little slippage in his command and control will really hurt him, and that is not uncommon in pitchers coming back from TJ.

      • tcostant - May 9, 2014 at 1:55 PM

        I was talking about coming back from in. I was more talking about guys needing it.

      Are you saying it’s better for the pitcher or the team for his clock not to be ticking? I think the player would much prefer to be paid like a major leaguer for the year of rehab.

      therealjohnc makes a good point about his age. It’s one thing if you’re a prospect and you’re young (Stras, Giolito, Bundy etc.), or if you’re an established major leaguer (Wainwright, Hudson). But if you’re a borderline pitcher at his age, this can’t be good news (J.D. Martin). While the chances of a “successful” surgery are very good, not everyone who has the surgery becomes a great pitcher (Ryan Matteus).

      • tcostant - May 9, 2014 at 1:58 PM

        Better for the team. We loss a year of Stras and another year had an innings limit. You look at Giolito, he now can deal with a year off an innings limit in the minors and when he gets to DC he could be around a 200 inning guy. I;m soory I wasn’t clearer.

        Got it. Thanks.
