HAVANA -- Jason Giambi hit two of his team's five home runs, as the United States routed Aruba, 12-0.
The United States (3-0) scored seven runs in the second inning to break open the game, which was halted after seven innings by the international 10-run rule. Giambi, out of Cal State Long Beach, has three homers in the tournament.
In other action, Mexico (2-2) defeated Nicaragua, 3-1, and Canada (0-3) lost to the Dominican Republic, 4-3.
For the fifth time, the U.S. women had a shutout, as Lisa Fernandez of Long Beach, Calif., threw a two-hitter in a 7-0 victory over the Bahamas. Not only do the American women have a 0.00 ERA, but they also have held hitters to a .027 batting average.
U.S. divers continued their dominance in the competition, as Jill Schlabach of Ann Arbor, Mich., won the American's fourth gold in four events by placing first in the women's 1-meter springboard with a total of 256.500.
Schlabach, a bodybuilder and surgical intensive care nurse at the University of Michigan Medical Center, said the noisy crowd at the City Sports Pool complex did not rattle her. "It's amazing that the whole crowd is so much into it," she said. "It was kind of neat."
Alison Malsch of Cherry Hill, N.J., won the silver medal with a total of 250.680, well ahead of Cuba's Mayte Garbey, who finished with 245.040 for her second bronze of the Games.
Track and field
Cletus Clark won in the 110-meter hurdles in 13.71 seconds to give the men's track and field team its first gold after it failed to win one in eight previous events.
"I thought we could use some more medals, especially a gold," he said.
Cuba picked up two more golds to continue its dominance of track.
Aliuska Lopez led a 1-2 Cuban finish in the women's 100 hurdles, and Barbara Hechevarria led the Cubans' sixth straight Pan Am 1-2 finish in the women's discus.
Boxer Kenneth Friday, the 125-pound, 29-year-old senior member of the U.S. boxing team, was fearsome as he stopped Nicaragua's Eddy Saenz with 40 seconds left in the second round of their opening bout. Friday landed four rights to the head before the referee broke in for a standing eight-count, then landed another right that persuaded the ref to stop it.
"Everybody looks for somebody to set the tone," Friday said. "Hopefully, this will set it and everyone will go on to the championships."
The win was crucial for the U.S. team, given little chance of winning golds against the veteran Cubans on their home turf.
Seven U.S. Greco-Roman wrestlers advanced to tonight's final round, where they will all face Cubans. Three other Americans will compete for bronze medals.
