Stanford righty Cal Quantrill, who appeared likely to be a top draft pick in 2016, is out for the rest of the season with elbow trouble and will have Tommy John surgery Friday, Jeff Blair of Sportsnet.ca tweets. Quantrill posted a 2.68 ERA with 8.0 K/9 and 2.8 BB/9 in 110 2/3 innings in his freshman year at Stanford in 2014 and was off to a good start in three outings in 2015. The Yankees drafted him in the 26th round in 2013. He is the son of former big-league reliever Paul Quantrill.
The Blue Jays took injured pitcher Jeff Hoffman with the ninth overall pick in 2014, and the Nationals selected another injured pitcher, Erick Fedde, with the No. 18 pick and have had great success so far with another prospect, Lucas Giolito, who was known to have elbow issues when selected. So Quantrill’s injury might not prevent him from being selected early in 2016, particularly since there’s time for him to be mostly recovered by the time next year’s draft rolls around. Nonetheless, Quantrill’s injury is part of an epidemic of elbow trouble for pitchers at all levels, most recently including Yu Darvish, Josh Edgin, Tim Collins, Brandon Cumpton and Joel Hanrahan.
