Jason Bay told us last week he was going to become an American citizen…

… and, evidently, he wasn’t lying. (We strongly encourage a Ray Bourque/Phil Esposito type of moment at Fenway tomorrow rather than the Manny Ramirez flag-waving route.)

(Per the Associated Press): Red Sox left fielder Jason Bay married an American, has two American daughters and makes his living playing America’s pastime.

Now he can say he’s an American, too.

The 30-year-old from Trail, British Columbia, was among 360 people to become U.S. citizens Thursday in a naturalization ceremony at Faneuil Hall.

Dressed in a suit, Bay blended into the diverse group of immigrants holding postcard-sized flags who took the oath administered by U.S. District Court Judge Leo Sorokin.

Bay joined two military men and about a dozen children of newly sworn-in citizens to lead the crowd in the Pledge of Allegiance. One little boy donned a special Red Sox T-shirt with Bay’s No. 44 decorated with red and white stripes and blue and white stars.

“I already knew it but I wanted to make sure I didn’t mess it up in front of all those people,” Bay said, admitting some jitters. “I didn’t want the kids to upstage me.”
