MONTREAL - Daniel Santos knocked out Joachim Alcine with a right-left combination 2:10 into the sixth round to take the World Boxing Association light middleweight title from the Montreal boxer on Friday night.
The 32-year-old Santos (32-3-1), of Puerto Rico, had outboxed a nervous-looking Alcine (30-1) in three of the first five rounds.
In the sixth, the southpaw Santos threw a jab up the middle and then floored Alcine with a left hook. Alcine tried to get up, but fell back on his side before a stunned home crowd of more than 8,000 for the open air bout at Uniprix Stadium.
The loss leaves Canada with three world title holders - IBF super-bantamweight champ Steve Molitor of Mississauga, Ont., and two Romanians based in Montreal, IBF super-middleweight champ Lucian Bute and new WBC light heavyweight champ Adrian Diaconu.
Alcine won the WBA belt in July 2007 from American Travis Simms in Bridgeport, Conn., and made a successful optional defence in December against Alfonso Mosquera. It was his first mandatory defence.
Santos is a champion for a third time. He held the WBO welterweight title from 1999 to 2001 and the WBO light middleweight belt from 2002 to 2005, finally losing it to Sergei Dzinziruk.
David Lemieux (9-0) of Montreal, the gifted 19-year-old who turned pro in 2007, took overmatched Oswaldo Gonzalez (1-8-1) of Mexico down three times before the bout was mercifully stopped at 1:53 of the second round of a light middleweight fight.
The bout was co-promoted by Groupe Yvon Michel and Don King, the electric-haired American who was a hit with ringside fans and even some boxers looking to have their pictures taken with boxing's best-known promoter.
In another title bout, Alex Bunema (30-5-2) retained the minor WBA Intercontinental belt by stopping Walter Dario Matthysse (26-4) of Argentina with a knockdown at the end of the sixth round of a scheduled 12-round fight.
Heavyweight Bermane Stiverne (15-1), a Montreal native who fights for King out of Las Vegas, made short work of previous unbeaten American Brad Gregory (10-1), ending the scheduled eight-rounder with his second knockdown 2:35 into the first round. It was Stiverne's first fight in Montreal.
Montreal welterweight Benyamine Besmi (10-0) was flattened by a left in the first round but came back to stop Baltazar (Matamuchachos) Perez (3-3) of Mexico in the fifth round of a free-swinging bout, and Tony Luis (2-0) of Cornwall, Ont., won all four rounds handily against Jean Charlemange (10602) of Montreal.
The scheduled co-feature between light middleweight Phil Lo Greco (15-0) of Montreal and Alejandro Juarez (15-1-1) was cancelled when the Mexican tested positive for Hepatitis C in a pre-fight blood test.
Before the main event, IBF super-middleweight champ Lucian Bute got a standing ovation when introduced to the crowd, while Montreal Alouettes quarterback Anthony Calvillo, Montreal Canadiens forward Guillaume Latendresse and Ultimate Fighting champion Georges St-Pierre got hearty applause and a load of politicians were booed.
