For somebody who arrived as damaged goods, Mike Napoli sure looks damn good.

For somebody who takes a weekly dose of osteoporosis medicine and must manage a degenerative hip condition with the ghastly name of avascular necrosis for the rest of his life, Napoli swings an awfully fierce bat, having already launched a pair of to-the-moon home runs this spring.

And for a new first baseman who was supposed to inherit the Bronze Glove that left fielder Manny Ramirez used to joke about, Napoli has been better than advertised: He’s looked nimble and sure-handed.

Thanks to medicine and Napoli’s hard work, he has stayed on top of the disease, but this is not a medical miracle tale.

The story of the 31-year-old Napoli’s resurgence starts at his hips, but it ends with a baseball decision.
