LOS ANGELES (AP): Armenian-Australian bocer Vic Darchinyan will embark on a revenge mission after destroying Mexico's Tomas Rojas in the second round of their super-flyweight world title fight.

The WBA and WBC champion fired a powerful left hand to Rojas's chin that left the Mexican flat on his back on Saturday.

Minutes after the devastating win at the Agua Caliente Casino in Rancho Mirage, outside Los Angeles, Darchinyan revealed his plan to avenge the two losses that blight his stellar 36-fight professional record.

''I want rematches,'' announced Darchinyan, who was cheered at the casino by a large contingent of Australian supporters, including IBO world cruiserweight champion Danny Green.

First on Darchinyan's revenge list is the ''Filipino Flash'', Nonito Donaire, who scored a surprise fifth-round technical knockout over Darchinyan in Connecticut in 2007. Then Darchinyan wants a rematch with Ghana's Joseph ''King Kong'' Agbeko.

Agbeko also was a surprise victor, on points, when Darchinyan stepped up a division to fight the African for the IBF bantamweight world title in July. ''Every night when I sleep I am thinking about when I'll fight those guys,'' Darchinyan said. ''It is in my dreams.''

Darchinyan's American promoter, Gary Shaw, confirmed his charge was working on a fight with the Filipino. ''We're going after Donaire,'' Shaw said.

Rojas became the most recent Mexican fighter to end up on the canvas after suffering at the hands of Darchinyan's punching power. His high-profile countrymen Jorge Arce, Cristian Mijares and Victor Burgos all ended up in hospital after losing to the Australian in recent years.

In the first round, the taller, longer-limbed Rojas appeared likely to live up to his bold prediction of taking away Darchinyan's WBC and WBA super-flyweight belts. Rojas hit Darchinyan with some solid blows, but the Australian said he was just patiently watching for weaknesses in Rojas's armour.

''He was confident because he hit me with a couple of good ones,'' Darchinyan said. ''I knew because he saw my left coming straight [and] he'd try to duck it. I didn't go for his head. I went for his chest and hit his chin.''
