This is unfortunate: Diamondbacks reliever Rubby De La Rosa will undergo Tommy John surgery. This will be the second Tommy John procedure of his career, the first coming back in 2011.
De La Rosa has had elbow issues for his entire career. Last year his UCL was barking again and he underwent stem cell therapy to try to avoid a second surgery, but it obviously hasn’t worked out. He’s pitched in only nine games this year, allowing four earned runs in seven and two-thirds innings, striking out 12.
I first saw De La Rosa in spring training in 2011. I thought his stuff was pretty phenomenal and figured he’d be a good one. Great stuff is often a function of heavy strain on an elbow, however, and pitchers breaking is, unfortunately, the rule in baseball far more than the exception.
He’ll miss a year at least. We likely won’t see him until spring of 2019, most likely on a minor league deal.
