Drabek, 28, is the son of 1990 National League Cy Young Award winner Doug Drabek. He was selected by the Philadelphia Phillies as the 18th overall pick in the 2006 first-year player draft and received a signing bonus of $1.55 million, but he has failed to live up to expectations in professional ball.
In 2009, the Phillies traded Drabek, catcher Travis d'Arnaud and outfielder Michael Taylor to the Toronto Blue Jays for pitcher Roy Halladay. Over parts of seven seasons with the Blue Jays, Chicago White Sox and Arizona Diamondbacks, Drabek has a major league record of 8-15 with a 5.
