"The swing has freed up a bit where he's able to address some pitches on the inside part of the plate where he was being attacked early the previous time he was up here."
Rubio (ankle) has been working on improving his jump shot and upper body strength in the four months since ankle surgery, Ben Golliver of Sports Illustrated reports. "I try to get 100-200 shots a day up without jumping," Rubio said.
