Mets infielder David Wright, who’s known for throwing out base runners, throws a good party, too. Wright hosted a surprise birthday bash for his fiancée, model Molly Beers, at Arlington Club steakhouse over the weekend. Guests included Mets hurler Matt Harvey and his girlfriend, Victoria’s Secret Angel Anne V. Spies said the group dined on 28-day, dry-aged filet, plus branzino and roasted chicken. Afterward, “David brought in a big cake for Molly, with candles,” said an onlooker. And, “Despite many of the women being models, they all also ate peanut butter-chocolate bars, banana cream pie and more.” Wright and Harvey are both potential starters at the All-Star Game at Citi Field on July 16.
