Monday, 7:10 PM – Jenrry Mejia
Mejia is making his second major league start of the season, after spending most of the year in Triple-A working back from his 2011 Tommy John surgery. The 22-year-old has a great arm, with a cutting fastball that sat 93-97 MPH and touched 98 MPH before the injury. In his limited time back in the big leagues, it seems that his velocity has completely returned. Mejia also throws a hard 85-90 MPH changeup and a 78-82 MPH curveball. He spent a good portion of the 2010 season pitching out of the Mets’ bullpen as a 20-year-old, and has mostly alternated between starting and relieving over the past two years. Despite the great raw stuff, he has not missed many bats in the majors, posting a well below average strikeout rate in his 45 career innings. Mejia often struggles with command, possibly due to an inconsistent release point.
