ANAHEIM, Calif. — Nonito Donaire stopped Wladimir Sidorenko at 1:48 of the fourth round of a scheduled 12-round bantamweight fight Saturday at the Honda Center.
Donaire (25-1, 17 knockouts) earned the right to challenge for Fernando Montiel's 118-pound titles on Feb. 19.
The Filipino-American dominated Sidorenko (22-2-2, 7 KOs) from the beginning, putting the Ukrainian down three times with overwhelming power shots.
Donaire hurt Sidorenko with a left hook midway through the first round and then put him down with a left hook-straight right combination. Sidorenko, his face covered in blood from a possible broken nose, went down from another left hook in the third round.
And, in the fourth, a left-right combination sent him to a knee and he declined to get up.
Sidorenko, a former bantamweight titleholder, had never been stopped in his career.
Afterward, Donaire was asked to compare this victory to his one-punch knockout of Vic Darchinyan in 2007.
“That was just one punch,” he said. “This was my best performance as a fighter.”
