When Upton was cleared for light jogging exercises Monday, it marked his first on-field activity since straining the adductor muscle on July 12. He hit off a tee on Tuesday and was hoping to be cleared to begin increasing his swinging activities over the next few days.
Upton will not be ready to be activated when he becomes eligible to come off the disabled list on Saturday. But if he continues to make progress, there is a chance he could begin a Minor League rehab stint next week.
