Adonis Stevenson stopped Chad Dawson with a left hook in the first round to take the WBC light heavyweight title Saturday night.
Stevenson (21-1), from nearby Longueuil, sent a crushing left to Dawson’s temple less than 2 minutes into the scheduled 12-round bout. Dawson (31-3-0) got up, but referee Richard Griffin stopped the fight.
Stevenson became the only Canadian to currently hold a world title.
Dawson, from New Haven, Conn., took the title last year from Bernard Hopkins.
On the undercard, Yuriorkis Gamboa unanimously outpointed Darleys Perez to win the interim WBA lightweight title. Gamboa (23-0), the 2004 Olympic champion from Cuba who now lives in Miami, floored Perez (28-1) with a left hook in the first round and received winning scores of 116-111, 115-112 and 115-112.
