Jon Niese’s rapid heart beat problems return


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.

David Phelps to undergo Tommy John surgery

Pitcher David Phelps has a torn UCL and will undergo Tommy John surgery, ending his 2018 season, the Mariners announced on Wednesday. Phelps was making brief one-inning stints in the Cactus League as he worked his way back from a procedure to remove a bone spur from his elbow last September. He said he felt the ligament tear on his final pitch against the Angels in his March 17 appearance.

Phelps, 31, was expected to set up for closer Edwin Diaz. The right-hander, between the Marlins and Mariners last season, posted a 3.40 ERA with a 62/26 K/BB ratio in 55 2/3 innings. He and the Mariners avoided arbitration in January, agreeing on a $5.55 million salary for the 2018 campaign. Phelps will become eligible to become a free agent at the end of the season.

As the Mariners noted in their statement, the expected recovery period for Tommy John surgery is 12-15 months, so this very likely cuts into Phelps’ 2019 season as well.
