Why not put the kid in the ring? Jonathan Ballan, the lead bond lawyer for the financing of Yankee Stadium, booked the stadium on June 5 for his son’s bar mitzvah. Now, Bob Arum, a boxing promoter, is negotiating to book the stadium for the same day for a bout between Yuri Foreman and Miguel Cotto. So far, Arum has agreed to give the bar-mitzvah party ringside seats, allow the bar mitzvah boy into Foreman’s dressing room before the fight, and to give the boy’s friends autographed baseballs. But the matter is still not settled. “The bar mitzvah saga continues,” Arum tells The New York Times.
