Via Jon Morosi & Erik Boland: Derek Jeter ran today for the first time since having left ankle surgery in October. It wasn’t much — five minutes on a treadmill — but it’s progress. The Cap’n also said he’s been given the “green light” to ramp up his rehab and basically do everything a baseball player needs to do to prepare for the season. That doesn’t mean he’ll be ready to go on Opening Day, just that his ankle is healing well and he can begin to pick up the pace a bit. Good news, obviously.
