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.
