Jon Niese was dominating the Cardinals when he left last night’s game. But the reason he left was not because he had no more worlds left to conquer, but because of the return of a problem he faced last year: a rapid heartbeat or, as the doctors call it, tachycardia.
This happened to him late last June in Texas. Afterwards he said it happened before that as well. He went through a battery of tests at at the time, including an electrocardiogram, echocardiogram and a treadmill stress test, all of which came back normal. He didn’t miss a start after it occurred in 2011.
Presumably he’ll be examined again. And hopefully this is just something that happens to him and doesn’t portend any greater health problems and no missed time.
A day after throwing an immaculate inning — getting through an inning on three consecutive strikeouts with nine pitches — against the Mariners, Dodgers reliever Zac Rosscup was placed on the 10-day disabled list with a left calf strain. The move made room on the 25-man roster for Kenley Jansen, who is back after missing some time due to an irregular heartbeat.
Rosscup pitched the ninth inning of Sunday’s 12-1 win over the Mariners. He struck out Kyle Seager, Ryon Healy, and Cameron Maybin on three pitches each. Rosscup is the fourth pitcher to throw an immaculate inning this season, joining Kevin Gausman, Max Scherzer, and German Marquez. 2018’s four immaculate innings is still far behind 2017’s record of eight.
Rosscup has pitched only 6 2/3 innings in the majors this year. He has yielded five runs (all earned) on seven hits and a walk with 10 strikeouts. He missed a significant amount of time earlier this season due to a blister on his left middle finger.
