Garcia, thought to be lost for the season after sustaining a torn labrum and avulsion fracture in his left shoulder on April 9, has five singles in 10 at-bats for Charlotte. He began his rehab assignment on Tuesday.
"Avi's doing good," Ventura said.
Ventura also said that pitcher Zach Putnam should be available to come off the 15-day disabled list on Friday, the soonest he's eligible.
"He's on track right now," Ventura said. "He's throwing tomorrow in Charlotte. He'll get an inning in there and see what he feels like."
