Royals manager Ned Yost said on Thursday that Perez, who is on the 60-day disabled list recovering from a torn meniscus, has been hitting in the batting cages and he's about a month away from coming back.
"Sal's getting close," Yost said. "He's probably, hopefully three weeks to a month away. I watched him hit in the cage and he's swinging the bat well. He's going to probably start catching side sessions after the weekend, start taking BP on the field after the weekend. That's good. He's getting close."
Royals starter Jonathan Sanchez left Thursday for Surprise, Ariz., for extended spring training. Yost said Sanchez, who is on the 15-day DL with biceps tendinitis, would throw some side sessions in Arizona and that he has had no setbacks. Yost added that a Minor League rehab assignment for the left-hander is probably a couple weeks away.
