KANSAS CITY -- Royals catcher Salvador Perez left for Arizona on Sunday to continue his rehabilitation from left knee surgery.
His assignments will include working with left-handed pitcher Jonathan Sanchez, who is on the disabled list with biceps tendinitis and is also at Royals extended spring training at Surprise.
"He'll be down there catching Sanchez and catching his sides, and catching his BPs and catching him in games. Taking batting practice and playing in games," manager Ned Yost said.
Perez is considered to be ahead of schedule in his recovery from March 16 surgery and might be back with the Royals within a month.
" I think he'll be back before a month, but that's just me," Yost said. "But if it's a month, I'll be happy."
