Mark Prior expected to attempt “one more comeback”

From Nick Cafardo’s Sunday notes column in the Boston Globe:

Mark Prior, RHP, free agent – He will likely attempt one more comeback. He spent some of last season with the Yankees, his rebuilt arm holding up well and getting his velocity into the low 90s. But Prior, who was the Stephen Strasburg of his day, has a new problem. After many weeks of trying to figure out what was wrong with the lower half of his body, he had surgery for a sports hernia, but the problem wasn’t completely corrected. He is working out near his home in San Diego, trying to figure it out. He will likely work out for teams as early as March.

Prior, the No. 2 overall pick in the 2001 MLB Amateur Draft, registered a promising 2.25 ERA, 0.75 WHIP and 15/4 K/BB ratio across 12 minor league innings last year. He hasn’t appeared in a major league game since the 2006 season, but he could score a spring training invitation if he’s healthy and throwing well before spring training concludes.

Rubby De La Rosa to undergo a second Tommy John Surgery

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.

Cardinal closer Trevor Rosenthal was taken out of last night’s game against the Red Sox after he gave up a big homer and a walk. He velocity was down as well, and Mike Mathney said after the game that he didn’t look right. Now the Cardinals are going to take a closer look at him, and he’ll be examined today for what is being described as “tightness” in his right arm.

Rosenthal is 3-4 with a 3.40 ERA and a K/BB ratio of 76/20 in 47.2 innings. He has 11 saves after regaining the closer’s job from Seung Hwan Oh. Now some combination of Oh, Tyler Lyons, and John Brebbia will fill in for Rosenthal to the extent he needs to miss time.
