Challenger Barry McGuigan of Ireland won the World Boxing Association featherweight title tonight with a unanimous decision over Eusebio Pedroza of Panama in a 15-rounder at the Queens Park Rangers soccer stadium.
Judge Ove Ovesen scored it 149-139, Fernando Viso 147-140 and referee Stan Christadoulou 148-138.
"I'm sure delighted," said McGuigan, 24, in tears before a crowd of 26,000. "I'm so glad to have beaten such a renowned champion."
When the decision was announced, the staunchly pro-McGuigan crowd stormed the ring, overrunning the press enclosure.
It was the first outdoor fight in London since May 1966, when Henry Cooper fought for Muhammad Ali's world heavyweight title.
Today's first six rounds were fought at a furious pace, with the tempo diminishing in the seventh, when Pedroza, 32, began dictating the pace. But suddenly McGuigan landed a right and left as Pedroza was moving away, sending him, first, onto the ropes, then to the canvas.
McGuigan staggered him again near the end of the ninth with a series of combinations.
A scheduled preliminary bout between Wilford Scypion and Herol Graham was canceled when the British Boxing Board of Control refused Scypion permission to box. X-rays had found him to have an "abnormality," such as brain damage, officials said.
