Matt Kemp is expected to be ready to play again when he is eligible to be activated from the 15-day disabled list May 29, according to trainer Sue Falsone. "That is our goal," Falsone said. Kemp was placed on the disabled list Monday with a strained left hamstring. The next day, Kemp received an injection of platelet rich plasma. He had blood drawn and spun to isolate the platelets, which clot and promote healing. The platelets were injected into the site of the injury.
