A brief round-up of the weekend's action;

GUERRERO DETHRONES KLASSEN

Robert Guerrero threw everything and the kitchen sink as he out-punched and out-boxed Malcolm Klassen en route to a unanimous decision by scores of 117-111, 116-113, and 116-112.

Tough for first round for Klassen who ate jab after jab and the occasional left hand and right hook from Guerrero who pressed the pace and action in the opening frame. Circling left, the southpaw Guerrero took control early and wouldn't let it go as he opened up with the jab and let combos flow off that until Klassen let his hands go late and got in a nice right hand. Relentless volume and crisp shots won Guerrero the first four rounds.

The steady pressure and solid defensive work of Klassen, who picked off and slipped shots, got him back in the fight as he countered with the right hand and dug to the body of the volume punching Guerrero, who rested on the ropes and lowered his output at times. While Guerrero never backed off with his volume of punches (throwing nearly 100 a round), Klassen stayed steady and landed the harder more telling blows over the course of the middle rounds which were a back and forth affair. Guerrero used volume with little heat to set the tempo and Klassen bore in with hard shots to the body and the occasional right lead. From seven to ten, Klassen seemed to take control and work his way in to Guerrero's body and willed his way to get in the right hand.

But Guerrero rallied in the eleventh and twelfth, both boxing and moving and throwing punch after punch to keep the tired Klassen off him. The class of both men showed for as tired as they were, neither ever backed off and kept exchanging down the stretch with Guerrero seeming to will himself to get off more punches to seal the victory.

Guerrero improved to 25-1-1 with 17 by KO's, whilst Klassen dropped to 25-5-2 with 15 KO's.

STIEGLITZ BATTERS BALZSAY

Super middleweight contender Robert Stieglitz surprisingly stopped previously unbeaten WBO champion and heavily favoured hometown favourite Karoly Balzsay in ten rounds to claim the WBO super-middleweight belt on Saturday in Budapest, Hungary.

It was a good action fight that became a war of attrition. As the rounds progressed, Stieglitz' pressure began to wear down the champion. The bout turned for good in round nine when Stieglitz rocked Balzsay and followed up with a brutal all out assault. Balzsay went down at the end of the round but it was ruled a slip by referee Joe Cortez.

In round ten, Stieglitz continued to punish Balzsay, who looked spent. Balzsay's trainer Fritz Sdunek stopped a wobbly Balzsay from coming out for round eleven. Balzsay was taken from the ring on a stretcher wearing a neck brace, but appeared to be alert and not too seriously injured.

Stieglitz improve to 36-2, 22 KO's whilst Balzsay dropped to 21-1, 15 KO's.
