KMOV's Maurice Drummond has confirmed that Cardinals starting pitcher Alex Reyes will undergo an MRI after missing his scheduled throwing session Tuesday.
Reyes, a righthander, was sent for a magnetic resonance imaging scan of his right elbow Tuesday afternoon. He will get a second opinion, but season-ending Tommy John surgery is possible, the report said. "Until we know exactly". He's an exceptionally hard thrower who can hit triple digits with his fastball, and Baseball Prospectus recently named Reyes as the top overall prospect in all of baseball.
General manager John Mozeliak said Reyes alerted team doctors before a schedule physical. He made his major league debut last August and earned a 4-1 record with a 1.57 ERA. While it certainly could have been a factor in his apparent arm injury, Reyes had the best velocity of any pitcher on the Cardinals' staff, touching 101.4 miles per hour with his fastball last season. If Reyes is unable to join them, then St. Louis would likely turn to Michael Wacha to be the fifth starter.
Based on Reyes' age and promise, he is a huge part of the Cardinals' pitching staff heading into 2017.
Reyes, who has been touted as a Rookie of the Year candidate, had been selected to pitch for the Dominican Republic in the World Baseball Classic.
