The left-hander, who has not pitched since April 17, is on the disabled list with a strained flexor muscle in his pitching arm.
The White Sox have been extremely cautious with, as well as tight-lipped about, his recovery.
“He’s progressing; he doesn’t feel anything,” manager Robin Ventura said. “Talking to him, he said everything feels good. You continue to go from there.”
When Sale might head out on a minor league rehab assignment, and how many outings he might need before he returns is yet to be determined.
“I think over this weekend we’ll have a better idea,” Ventura said. “He’ll throw again probably Saturday and from there you figure out how he’s feeling and then you make a plan from there. He’ll have to make a rehab start. Then you’re not going to just start him and have him go 80 pitches, it will probably be a short one to start out, see how he’s feeling and go from there.”
