From untested prospect to unbeaten world champion, Jaime Munguia drops Sadam Ali four times to win WBO junior middleweight title

He came in as an unbeaten prospect. Now, he is an unbeaten world champion.

Jaime Munguia destroyed Sadam Ali to take the WBO junior middleweight title in a brutal, four-round beatdown Saturday night in a HBO-televised main event at Turning Stone Resort & Casino in Verona, New York.

Ali (26-2, 14 KO's), 29, of Brooklyn, New York, was defending the belt he won in December when he scored an upset victory over the now-retired Miguel Cotto.

The 21-year-old Munguia (29-0, 25 KO's), of Mexico, had no problems finding Ali early, not even in the first round, when he sent the 2008 Olympian flying with a clean left hook right on the jawline. Later in the round, Munguia knocked down Ali again, but this time with a right hand. Ali was out on his feet, but somehow managed to survive the round.

Ali briefly rallied, but was sent to the floor once more at the end of the second round after Munguia landed a powerful right hand, followed by another series of blows, as Ali wobbled and stumbled around.

In the fourth round, Ali was the elevator shaft once again -- up and down -- but referee Gary Rosato immediately halted the fight after Ali was dumped yet again by a lead left hook.

Statement made.
