Puerto Rico's Wilfredo Vazquez Jr. won the vacant WBO junior featherweight title tonight with a fourth round knockout of 19-year-old Filipino sensation Marvin Sonsona, badly outboxing the youngster before finishing him off with a straight right to the head and a left hook to the liver.

Vazquez (18-0-1, 15 KO) looked overwhelmed by Sonsona's speed in the opening round, but after that he took over. He took Sonsona (14-1-1, 12 KO) to school in a tactical sense before putting him on the canvas to end it.

Vazquez wasn't ranked by many at 122 pounds, but I'm betting he finds his way into more top 10s tomorrow than just ours. He showed a lot of skill tonight, stayed calm, and picked Sonsona apart. Sonsona was faster for sure, but Vazquez was able to make him look tentative and reluctant by leading the action after the first round ended. As Vazquez picked up steam, his confidence clearly raised, and he was able to cash in with big shots.

Sonsona might consider going down to 118 pounds if he can. There's the feeling among plenty of commenters here and I'm betting elsewhere that Sonsona doesn't yet have his heart in boxing. He's a 19-year-old kid who rose really fast in the pro ranks. If this loss wakes him up, he's got a super amount of ability that he can put to great use. If it deters him, he will probably never reach his potential.

He's at a fragile place for sure.

But congratulations to Vazquez for his tremendous win, and for gaining his first world title. I've got a feeling we're going to be hearing a lot more from Vazquez, and seeing a lot more of him on major TV in America.
