"He's doing some light work," Twins manager Ron Gardenhire said. "He's eligible to come off on our road trip, and that's the target date. But they still haven't allowed him to get on the field and run around."
Twins general manager Terry Ryan added that Santana won't need long to get ready once his knee heals and he's allowed to fully resume baseball activities. But if he can't return next weekend, he'll likely go on a rehab assignment to stay sharp over the All-Star break.
"If he's ready to go, we'll activate him in Colorado, but I don't know if he will be," Ryan said. "But it's not going to take him long once they give him the green light. He's getting better daily."
