Struggling Sox third baseman Will Middlebrooks and girlfriend Jenny Dell joined former Mayor Tom Menino and wife Angela at Good Sports’s annual Legends of the Ball fund-raiser at Fenway. A chance to play Wiffle Ball with Middlebrooks was auctioned for $10,000 and two private street hockey clinics with Bruins goalie Tuuka Rask raised another $20,000 . . . Why was there a pony in a ballroom at the Ritz Carlton? It was a fund-raiser for the BINA Farm Center, which provides therapeutic and recreational programs using equine-assisted activities. Keith Lockhart’s wife, Emiley, was among the event’s cochairs. . . . The National MS Society’s Greater New England chapter held a gala the other night, and the honoree was Genzyme CEO Dr. David Meeker. . . . Sox CEO Larry Lucchino was feted this week for his support of the Leonard P. Zakim Center for Integrative Therapies at Dana-Farber Cancer Institute.
