Hynes spent 6 and a half seasons in the minors after being drafted by the Padres in 2007. His overall ERA in those seasons was 3.59 with a record of 21-25. Prior to being called up to the majors, Hynes sported a 1.52 ERA in 2013 with the San Antonio Missions and the Tucson Padres (now El Paso Chihuahuas). This July, Hynes made his major league debut and encountered some struggles in the majors. Over the span of 22 games, Hynes finished the season with a 9.00 ERA in 17 innings. You do the math and that's 17 ER this season.
A change of organization might be able to help the 28-year old left-hander in trying to regain the pitching success he had while a member of the Padres organization prior to reaching the majors. Best of luck to him in the future.
