Impact Thomas had been on the verge of returning earlier this month but felt something in his injured left hamstring after a rehab game at Triple-A Reno on May 5. He has since received a platelet-rich plasma injection and begun ramping up again -- running in a pool and taking live at-bats. Thomas made 13 plate appearances over three games during his first rehab assignment, which may be a barometer for how much time the outfielder needs on a second rehab stint.
