In closing the show of an HBO Boxing After Dark doubleheader, Adamek fought a smart fight by using his speed to inflict damage and never standing still long enough for Arreola to cash in on his power advantage.
Adamek's cumulative punishment showed on Arreola's battered face and was rewarded with two judges scoring the fight in his favor 115-113 and 117-111, while the other judge called it even 114-114.
"My dream is to be a three-category champion," said Adamek, who lifted his record to 41-3 with 27 knockouts and advanced his quest toward a potential heavyweight title shot.
Despite being outweighed 250 1/2 to 217 pounds and taking some punishing shots from the bigger man, Adamek used his slickness and quickness to score enough blows to convince not only the judges, but Arreola as well.
"He's a great fighter," said Arreola, whose record dropped to 28-2 with 25 KOs). "I didn't plan on him beating my ass, but be beat me. Look at me. I look like Shrek right now. He fought his game plan to perfection.”
Arreola, a local favorite from Los Angeles, said he hurt his right hand early in the fight, but really showed evidence of it in the 10th round when he winced after landing a glancing shot off the top of Adamek's head.
"I just kept kept going and going, but finally, I really hurt it," he said, "He has a hard head.”
Adamek (41-3, 27 KOs) was fighting just his third fight as a heavyweight and passed the test against the best one he's faced yet.
"He's in good condition, but I'm smarter and I'm faster and I won," said Adamek, a native of Poland who now fights out of Jersey City, N.J. said. "I was never hurt.”
In the first fight of the night, Alfredo Angulo used a devastating right hand to retain his WBO junior middleweight title with a TKO at 1:39 of the 11th round against Colombia’s Joel Julio.
Referee Raul Caiz Jr. called a halt to the bout after Julio scrambled to his feet but was obviously still too dazed to continue.
Angulo (18-1, 15 KOs), a native of Mexicali, Mexico who fights out of nearby Los Angeles, spent the early rounds trying to catch up with his fleet-footed, combination-throwing opponent but seized the advantage once Julio (35-4, 31 KOs), from began to slow down.
Having built a lead through the middle rounds, Angulo struck with sudden fury by landing a ripping right to the jaw after Julio’s lowered left hand made him an easy target.
