The 24-year-old Cooney was named to the Pacific Coast League All-Star team a day before being recalled from Triple-A Memphis.
Jay has struggled coming off wrist surgery in the offseason and is batting .223 with one homer and 10 RBIs in 57 games. He was also on the DL in May with left wrist tendinitis.
Cooney is 6-4 with a 2.74 ERA in 14 starts at Memphis and has held opponents to a .195 batting average, best in the PCL.
