ATLANTIC CITY, N.J. — Mariusz Wach stood tall in a casino ballroom, clutching his WBC title high over his head, and enjoying the moment with dozens of Polish countrymen who crashed the party.

"Polska! Polska! Polska!"

The post-fight chant was the same raucous one that greeted Wach as he made his entrance for his international heavyweight bout. Wach gave his fans a reason to celebrate, punishing Tye Fields with a serious of blows to the head before finishing him off in the sixth round Saturday to retain his title.

"I felt there was no way in hell you can beat me over here with my crowd and my people," Wach said.

Wach (27-0, 15 KOs) was never seriously hurt by Fields. Wach unloaded a series of lefts and rights at the head, caught Fields with one final right and sent him into the ropes and face first onto the canvas. Fields (49-5, 44 KOs) made it to his knees but could not get up at 1:44 of the round.

After a methodical first four rounds, Fields took a beating in the fifth. Wach targeted Fields' face for most of the fight, bloodied his nose and left him staggering in the fifth. The 6-foot-7 Wach won his seventh straight bout by knockout or TKO in a streak that dates to 2009.

The win moves Wach closer to a potential heavyweight title fight against Vitali or Wladimir Klitschko.

Wach said he would take a week off before he starts training for his next fight.

Andrew Golota, who lost four heavyweight title fights, sat ringside for most of the slate.

On the undercard, Artur Szpilka (10-0, eight KOs) defeated Terrance Marbra (6-2, five KOs) in the first round. Also from Poland, Szpilka spoke Polish to the crowd after the fight, sending the fans into a frenzy.

Kamil Laszczyk (8-0, five KOs) won a unanimous decision over Philadelphia fighter Tevin Farmer (4-3-1, one KO) to win the vacant WBO youth super featherweight title.

Jerson Ravelo, who fought for the Dominican Republic in the Sydney Olympics, defeated Joey Spina in an eight-round split decision. Stivens Bujaj (7-0, five KOs) earned a second-round TKO over Joshua Harris (8-6-2, six KOs).
