Dominican Republic ? Once again, there will be no Pan American Games gold medal for the United States in men’s basketball.

Brazil won Tuesday night’s semifinal game, pulling away in the fourth quarter for a 92-80 victory over the American collegians. The United States has not won the Pan Ams since 1983 — when the team included Michael Jordan, Chris Mullin and Wayman Tisdale. Brazil outscored the Americans 28-17 in the final period, including a 13-0 run.

The host Dominicans beat the Puerto Ricans 79-65 in the other semifinal and will play Brazil tonight.

In an early start to the busiest day of the Pan American Games, the U.S. baseball team returned to Quisqueya Stadium just 10 hours after beating the hosts before a sellout crowd. With far fewer spectators this time — perhaps 200 as opposed to 20,000 — they were four-hit by Nicaragua’s Olman Rostran and lost 3-0, breaking a 25-game string of victories this summer.

“We wanted to go undefeated,” designated hitter Stephen Head said, “but it just wasn’t there for us today.”

Stunningly, victory was there for the U.S. men’s foil squad, which scored the first team win in 32 years over the Cubans at the Pan Ams. The fencers trailed 40-30 entering the last match, which Dan Kellner of Warren, N.J., won 15-4, setting off a celebration long in the making.

Also celebrating were Cuba’s Eric Lopez and Chellsie Memmel of West Allis, Wis., in gymnastics. Lopez won all four events he entered Tuesday, giving him six gold medals in these games and 18 for his career. Lopez previously won the all-around title and the team gold, and added wins in pommel horse, rings, vault and parallel bars.

Despite his incredible success at the Pan Ams, Lopez has yet to win an Olympic medal.

“I want to close my career with an Olympic medal of any color,” Lopez said. “Then I can retire at the top.”

Memmel, 15, didn’t quite match Lopez, but she became the only American with three golds when she won the uneven bars. Memmel also won the all-around and the team event.

Teammate Nastia Liukin, 13, of Plano, Texas, won the balance beam, with Memmel getting bronze.

Shannon Pluhowsky of Phoenix rolled a 246 to capture the gold medal in women’s singles bowling. She previously won a silver in doubles.

“It means a lot, because this is as close as we’ll ever get to the Olympics,” Pluhowsky said. “This is the top.”

America’s shooting team collected two more gold medals, by Daryl Szarenski of Saginaw, Mich., in men’s 50-meter pistol, and 1996 Olympic champion Kim Rhode of El Monte, Ark., in women’s double trap.

In women’s basketball, the improving U.S. collegians beat Argentina 93-78 to advance to the medals round. Rebekkah Brunson of Georgetown and Loree Moore of Tennessee each had 12 points for the United States (3-1).
