Top prospect Bundy to undergo Tommy John

Baltimore Orioles' Dylan Bundy walks to the dugout.

Dylan Bundy, who began the 2013 season as the top pitching prospect in baseball, will undergo season-ending elbow surgery.

The Baltimore Sun’s Dan Connolly reported Wednesday that the Baltimore Orioles prospect will have Tommy John surgery Thursday to repair a partial tear in his elbow.

The 20-year-old right-hander has not pitched since March due to forearm discomfort. He’s expected to miss at least 12 months to recover from the operation.

The Orioles obtained Bundy with the fourth overall selection in the first round of the 2011 draft. He made it to the major leagues the following year, appearing in two games for the Orioles.

Bundy blazed through the minor leagues in 2012, his first season as a professional. He posted a 2.03 ERA across three minor-league levels, compiling 119 strikeouts in 103.2 innings.

Bundy entered the 2013 season as the second-best prospect in the sport, according to Baseball America.
