Ventura, 22, left in the third inning of his start against the Astros on Monday after giving up five runs in 2 2/3 innings. The rookie, whose fastball usually runs close to 100 miles per hour, was throwing fastballs as slowly as 91 mph.
From the Kansas City Star:
"He spoke with trainer Kyle Turner for a few moments. He used his jersey to wipe the sweat off his brow. Turner motioned to manager Ned Yost, and departed the mound with the 22-year-old. The subsequent ovation was muted, a stunned near-silence inside a packed Kauffman Stadium."
The injury was a reminder of the many pitchers who have gone down this season. Season-ending Tommy John surgery has sidelined plenty of pitchers, including Marlins ace Jose Fernandez.
Ventura is 2-4 with a 2.80 ERA in nine starts this season. SI Wire: Mets release RHP Jose Valverde, fire hitting coach Dave Hudgens
