Tonga McClain Advances in Moscow Bouts

Sharp-punching Tonga McClain advanced at the World Amateur Boxing Championships today, but two other Americans lost.

Six members of the young 12-boxer U.S. team have seen action, and three have lost.

McClain, 19, of Racine, Wis., bombarded Oshio Osawa of Japan with head blows and scored a 38-14 victory under the new computerized scoring system in a 132-pound bout.

McClain tired in the third round but had the bout in hand by then.

The U.S. losers were Paul Vaden, 21, of Puyallup, Wash., at 156 pounds, and Larry Donald, 22, of Cincinnati, a super heavyweight.

Vaden did little in losing 16-11 to a busier Lazlo Gal of Hungary.

Donald boxed well in the first round, then started getting tagged by hard right hands from Svilen Russinov of Bulgaria, who rallied for a 17-15 win. Russinov was a bronze medalist at 201 pounds in 1986 world championships.

Raul Marquez of Houston scored a 31-7 decision Tuesday night over Javier Martinez of Spain in a 147-pound bout, and Frank Pena of Aurora, Colo., put on a display of power against Peter Jacobsson of Sweden.
