Aumont was one of the prospects that the Phillies received from the Seattle Mariners back in 2009, when they traded Cliff Lee. He will be the first of the three prospects (Tyson Gillies and J.C. Ramirez are the other two) that the Phillies received from Seattle to make it to the majors.
The 23-year old reliever is 3-1 with a 4.26 ERA in 44.1 innings pitched with Triple-A Lehigh Valley, this season.
His upside? His fastball is in the high 90's.
