I wondered yesterday why the Cardinals would demote Mitchell Boggs to Triple-A after he had one bad week following 95 innings of solid relief work, but now we know: He’s going to work as a starter.
Tony La Russa told Tom Krasovic of MLB.com that the idea is for Boggs to develop his secondary pitches while starting every fifth day at Triple-A, adding: “I expect him back this year and to play a major role.”
However, it sounds like that “major role” may still involve returning as a reliever, albeit a reliever with an improved changeup and off-speed stuff. Pitching coach Dave Duncan indicated that Boggs’ return date is undecided, as is his return role.
Still an odd move, but now at least it’s an odd move with some reasoning behind it beyond “he’s pitched poorly for the past week.” Boggs had a 3.66 ERA, .233 opponents’ batting average, and 19/4 K/BB ratio in 20 innings before the demotion.
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.
