Kenley Jansen was hospitalized in Denver earlier this week due to an irregular heartbeat. He missed a month last season with the very same issue and he’ll soon find out whether his recent scare will cost him the rest of the season.
According to Dylan Hernandez of the Los Angeles Times, Jansen threw a 25-pitch bullpen session on Friday and plans to play catch today. He’s scheduled to see a heart specialist on Tuesday, who will tell him whether he must continue taking a a blood-thinning medication. His medication prevents clots and strokes, but can also cause severe bleeding. He could bleed to death if he was struck by a baseball, so he isn’t even allowed to sit in the dugout while taking the medication.
If Jansen is cleared by the specialist, he could pitch again as soon as next Friday against the Giants. However, if he is instructed to continue taking the medication, he will not be allowed to throw for four weeks. That would essentially end his season.
Health obviously comes first here, but it’s still a tough break for Jansen, who stepped into the closer role at the end of April and has a 2.54 ERA and 86/19 K/BB ratio over 56 1/3 innings this season. Brandon League and Ronald Belisario are expected to split save chances during his absence.
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.
