A talented outfielder from the University of South Carolina, Bradley was taken in the sandwich round -- 40th overall -- by the Red Sox.
After undergoing left wrist surgery, Bradley has a .259 average over 37 games this season, with six homers and 26 RBIs.
"He had the wrist injury. Jackie's not officially part of the organization yet, so it wouldn't be appropriate for me to comment in detail," said Red Sox general manager Theo Epstein. "But obviously we reviewed the medical file. It's something our medical staff was really comfortable with, that he'll be able to come back at 100 percent."
At 5-10, the 21-year-old has power and a nice middle-of-the-field approach. Bradley is a left-handed hitter, and he hails from Prince George, Va.
The Red Sox selected Bradley with the compensation pick they had for losing free agent Adrian Beltre to the Rangers.
