SCOTRUN, Pa. (AP) _ Lennox Lewis is looking to knock out Evander Holyfield in their heavyweight championship rematch Nov. 13, and that worries Emanuel Steward, Lewis' trainer.

``I'll throw a lot more punches, a lot more body shots and take a lot more chances,'' said Lewis, the WBC champion, who fought a majority draw against WBA-IBF champion Holyfield March 13 in a fight most ringsiders thought Lewis won clearly.

Taking more chances by a fighter known for his caution is what worries Steward.

``Lennox Lewis, the fighter, wants a knockout, not Emanuel Steward, the trainer,'' Steward said Thursday. ``In the first fight it was the other away around.''

Many boxing observers thought Lewis could have knocked out Holyfield in the March fight at New York's Madison Square Garden.

``He realizes he should have knocked him out,'' said Steward, who wants fire, not recklessness, from the champion from Britain in the rematch.

``Lennox doesn't have to change his style, just his intensity,'' Steward said before Lewis worked out for members of the media at Caesars Brookdale resort.

Holyfield said he had stomach cramps before and leg cramps during the March fight.

``There's about five different reasons when he loses,'' Lewis said. ``He's living in a fantasy world, and I'm going to wake him up to that fact.''
