HOUSTON -- Catcher Salvador Perez, on a rehabilitation assignment with Triple-A Omaha, had four singles in four at-bats on Wednesday, boosting his average to .340 in 11 rehab games.
The Storm Chasers lost to Memphis, 13-9.
Perez, 22, who had left knee surgery in March and has missed all of the regular season, also caught for the Storm Chasers on Tuesday night. Catching in a day game after a night game is a good sign that Perez will soon be back with the Royals.
Manager Ned Yost said he didn't have expectations to get Perez back for this weekend's home I-70 Series against the Cardinals. Last year, Perez batted .331/,361/.473 with three homers and 21 RBIs in 148 at-bats.
Perez signed a five-year, $7 million deal this offseason.
