ST. LOUIS -- Catcher Salvador Perez's rehabilitation assignment with Triple-A Omaha continues to go well, but there's no date set for him to join the Kansas City club. He's missed all of the regular season following left knee surgery in March.
"Probably won't see him during this trip," manager Ned Yost said before Sunday's series finale against the Cardinals.
Perez, in his first nine games for Omaha, batted .333 (13-for-39) with two doubles and seven RBIs.
"I don't care what he's hitting, I just check the health of his knee," Yost said. "He feels great after every day. He caught seven innings in the first game of a doubleheader [Saturday] and he'll catch nine innings [Sunday]."
Center fielder Lorenzo Cain, out since the first five games of the season, will begin a new rehab assignment on Monday with Double-A Northwest Arkansas. He was playing for the Naturals getting over a groin strain when a torn hip flexor dealt him a setback.
In addition, catcher Manny Pina, out with knee surgery, is to begin a rehab assignment soon.
