Whitman (MA) boxer Mike Bad Man” O’Han, Jr. (11-1, 5 KOs) dominated Ryan Dibartolomeo (3-1-1, 1 KO) from start to finish in the main event, nearly pitching a complete shutout, winning every round on two of the judges’ cards, all but one on the other, to capture the vacant New England welterweight crown.

The two fought in close quarters throughout 8-rounds, but Rolfe found himself on the ropes too often, and that’s where Marshall took advantage to win a decisive 8-round unanimous decision by scores of 79-71, 79-73 and 78-74.

Journeyman Larry “Slo Mo” Smith (12-44-2, 8 KOs) knocked out Jesus Cintron (1-16-2, 0 KOs) in a rematch of a fight this past August at the same venue, in which Smith won for the first time in nine years, a unanimous 4-round decision to a very late replacement in Cintron.

Maryland cruiserweight Larry “Hitman” Pryor (13-22, 6 KOs) overcame a wild start to defeat pro-debuting Scott Lambert, who came out of the corner throwing bombs.

Referee Gerstel had seen enough, and he halted the action for a technical knockout.
