Mets RHP Zack Wheeler allowed five runs on seven hits in three innings against the Nationals on Tuesday night.
Wheeler struck out three batters and walked two in what was his fourth outing of the spring. His ERA jumped from 1.80 before Tuesday's outing to 6.75 after he was finished.
The 27-year-old seemingly threw as hard as 99 miles per hour in the first inning before he went on to allow three runs in the inning.
Wheeler fared better in his previous outing against the Yankees, when he struck out four battters in three innings.
Wheeler, who is vying for a spot in the Mets' rotation, missed all of the 2015 and 2016 seasons amid Tommy John and other injury setbacks. He started 17 games in 2017 and went 3-7 with a 5.21 ERA, but his season was cut short by a stress reaction injury.
In an effort to avoid injury issues in 2018, Wheeler underwent six months of bone-strengthening injections.
