Australian Tszyu Downs Harrison in Sydney
SYDNEY (Reuters) - Tim Tszyu stopped American Tony Harrison in the ninth round at Sydney Arena on Sunday to win the interim WBO super welterweight belt and almost certainly set up a winner-take-all fight with unified world champion Jermell Charlo.
Tszyu, the son of former undisputed light-welterweight world champion Kostya, sent Harrison to the canvas with a volley of punches. Although his opponent regained his feet to beat the count, the referee stopped the fight.
The 28-year-old Australian, who improves his record to 22-0 with 16 knockouts, was supposed to fight Charlo in January before the veteran American, who owns the WBO, WBC, IBF and WBA light middleweight belts, broke his left hand.
Tszyu instead lined up 32-year-old Harrison, a former WBC champion and the only boxer to have beaten Charlo, and on Sunday burnished his credentials with an impressive victory.
The Australian was always on the front foot against the experienced Detroit native, who relied on his razor sharp jab and ringcraft to keep the younger fighter at bay.
In the third, Tszyu landed a big right hand on the counter that rocked Harrison onto the ropes but the American survived until the end of the round and worked the inside to get himself back into the fight.
