Caminero (quadricep) will begin a rehab assignment Tuesday with the Rays' rookie-level Florida Complex League affiliate, Sam Dykstra of MiLB.com reports.
Caminero has been shelved since late May with a Grade 2 left quadriceps strain but has finally been cleared to return to game action. After getting in a few rookie-level contests, the top prospect will eventually move back up to Triple-A Durham, where he's slashed .261/.333/.478 with eight home runs over 153 plate appearances this season. Caminero could still receive a promotion to the Rays after the All-Star break, but at this point, he probably won't be called up until at least August.
