Peralta had been with Onyx Sports Management.
The 27-year-old Peralta broke onto the scene as a very good outfielder with the Diamondbacks last season, hitting .286/.320/.450 with eight homers and 36 runs batted in over 348 plate appearances with Arizona.
Peralta has started off on a similarly hot start this season, hitting two homers in his first 11 games already, with his OPS nearly 100 points better than what it was last season. Though it is a small sample, Peralta is still trying to prove that he is not a fluke.
