Pats tight end Rob Gronkowksi is a busy fellow. The beefcake pass catcher, who last week signed a multimilliondollar contract extension, was in Vegas over the weekend judging SpyOnVegas’s Hot 100 bikini contest at the Wet Republic Ultra Pool at the MGM Grand. But Monday, he was back in Quincy golfing with a gaggle of his teammates at a fund-raiser for the Joe Andruzzi Foundation. Also knocking it around at the Granite Links Golf Club were Rob Ninkovich, Jerod Mayo, Dane Fletcher, Jermaine Cunningham, Dan Koppen, Nate Solder, Logan Mankins, ex-Pats Tedy Bruschi and Kevin Faulk, and comedian Lenny Clarke. . . . Meanwhile, Pats punter Zoltan Mesko knocked it around Monday at the Mass Eye and Ear Golf Classic at the Weston Golf Club. Mesko joined hospital CEO John Fernandez, Dr. Michael Rho, architect Rick Kobus, and Channel 5’s Bob Halloran, among others. (Wednesday, Mesko will be golfing again, this time at Plymouth’s Pinehills Golf Club as part of the annual Doug Flutie Jr. Tournament of Legends benefiting the Doug Flutie Jr. Foundation for Autism). . . . Pats players Aaron Hernandez and Niko Koutouvides were back in their native Connecticut over the weekend for an autograph signing at Mohegan Sun. . . . In town for a show at the Bank of America Pavilion, Beatles drummer Ringo Starr lunched at the Bristol Lounge at the Four Seasons Monday. . . . Chelsea-bred White House speechwriter Joe Resnek and his buddy Lorenzo Recupero ran into Celts forward Jeff Green while wandering the streets of D.C. over the weekend.
