Sugar Ray Leonard silences his critics
LAS VEGAS, Nev. (UPI) — Undefeated Sugar Ray Leonard may have finally silenced the critics who questioned the former Olympic champion's punching power.
Leonard, a 23-year-old boxer from Palmer Park, Md., scored a convincing victory Sunday with a technical knockout over Tony Chiaverini, who failed to answer the fifth-round bell.
Chiaverini, 153, a left-handed brawler with power in either hand, could not formulate a defense against the lightning-quick left jabs of Leonard. Leonard, 151, seemed to find the mark almost at will against the slower-moving Kansas City, Missouri, fighter.
Leonard, beginning the fourth-round in a flurry of punches, appeared in trouble after the opening minute — when Chiaverini maneuvered him into a neutral corner and began punching at Leonard's body. Chiaverini's strong arms prevented the younger boxer from freeing himself, although Leonard finally escaped from the corner and was unhurt.
The corner exchange angered Leonard, who swiveled his hips and mocked Chiaverini after the referee separated the fighters. Leonard systematically moved in to send jab after jab to Chiaverini's face, first opening an inch-long gash below the right eye, and then nearly closing the eye by round's end.
Critics had questioned Leonard's punching ability, noting he had been forced to go 10 rounds in each of his last two bouts prior to the Chiaverini matchup.
Leonard, who has 14 knockouts, won a tough unanimous decision over Marcos Geraldo May 20 in Baton Rouge, La., and prior to that, was forced to go the distance in winning a decision from Adolfo Viruet of New York April 21.
"He‘s about as fast as I thought, but he hits a little harder,” said Chiaverini following the bout. "He also caught me with a good one in the throat."
Chiaverini said his corner stopped the fight, rather than see the 26-year-old boxer get hurt.
Leonard, already signed to fight Wilfredo Benitez of Puerto Rico for the World Boxing Council welterweight crown Dec. 1 in the United States, said he planned to take July off and line up two bouts prior to his title shot.
Leonard and his handler Angelo Dundee refused to reveal who the charismatic boxer would meet next. Leonard said he eventually hoped to meet Roberto Duran, the former lightweight champion who gave up his crown to move up to the welterweight class. 
Howard Cosell: "He [Leonard] said he would have him [Chiaverini] figured out by the third or fourth round. It turned out to be both rounds. He said that he might not just knock him out, but he may just swell him up and render him helpless. He was a soundly thrashed fighter, as this young fighter is on perhaps the precipice of professional greatness."
