NEW YORK — A lost Red Sox World Series ring is back on the finger of its owner, thanks to a nifty pickup by an ardent New York Yankees fan.

Manhattan restaurant owner Luigi Militello could hardly believe it when he found the shiny 2013 championship ring on a restaurant sink at his Luke’s Bar and Grill on Thursday night.

It was the real thing, with diamonds and sapphires and rubies, set in 14-carat white gold, with the Red Sox emblem, a Boston Strong logo and an image of the team’s bearded ballplayers.

Drew Weber had dined at the restaurant earlier; it’s one of his favorite spots. He’s a New York businessman and also owns the Lowell Spinners, a thriving short-season Class A team in the Red Sox system.

Weber said this was the first time he’d worn the ring outside.

“I went looking around my apartment and started having palpitations. Sweat was pouring off my forehead,” he told the AP. “I’m looking at my finger and it’s not there.”

Hoping against hope, Weber called Luke’s after midnight. Militello answered the phone and said, yep, he had the ring.
