"When he keeps throwing, you hear feedback that he gives," said Ventura of Sale, who was scheduled to play long toss Wednesday. "He'll know when he's able to get on there and know when he's closer.
"Right now, he's getting closer, but I think if you keep going, he might end up getting to a point where he might have to go do one rehab start, something short. I know in the past we've done some simulated games, which would have to happen first, and we would talk about that. If it keeps going further and further, we'll probably get closer to doing a rehab assignment."
Both Ventura and White Sox pitching coach Don Cooper don't have a time in mind for a bullpen/side session for Sale, who will not pitch this weekend in Cleveland when he's eligible to come off the disabled list. Ventura also wouldn't state categorically that Sale will first need that Minor League rehab appearance.
"No, no. I don't know for sure it's going to happen, but it is a possibility," Ventura said. "I can't guarantee that's going to happen.
"He's feeling better. But before you send him out there you want him to feel really good. That's the reason for keep holding him off."
