All Vasyl Lomachenko. Landed an average of 31 of 77 total punches per round and 23 of 39 power shots (58%). It's not just his offense though: Jason Sosa landed an average of just 8 of 32 punches per round. Junior light average 17 of 58.

OXON HILL, Md. - Frustrated that he can't get fights against the opponents he wants, Vasyl Lomachenko took his frustration out on Jason Sosa.

Lomachenko (8-1, 6 KOs) dominated his WBO junior featherweight title defense before Sosa's own corner stopped the fight after the ninth round, completing a three-fight Ukrainian sweep on Saturday night.

After a bout in which even Sosa's corner admitted they were the third choice, Lomachenko says he's eager to unify titles.

Sosa (20-2-4) was a WBA belt holder at 130 pounds, but was forced to vacate to take this fight.

"I'll go home, rest, and then I want to negotiate with all the other champions in my division," Lomachenko said. "If they refuse to fight me, I'm going to move up to 135."

In front of a heavy Ukrainian contingent in a sell-out crowd of 2,828, Lomachenko battered Sosa, who finished with a badly swollen left eye.

At one point in the sixth round, he mocked Sosa with a matador gesture, to the delight of fans who chanted his name and "Ooo-Cray-Nee-Ahh" throughout while waving blue and gold Ukrainian national flags.

By the ninth, it had become clear to Sosa's corner that this was a no-win proposition.

Aleksandr Usyk (12-0) defended his WBO cruiserweight title with a 117-110 unanimous decision over Mike Hunter (12-1) in the first fight of an HBO TV card and the maiden boxing event at the MGM National Harbor.
