SANTO DOMINGO, Dominican Republic -- The United States had its 25-game baseball winning streak snapped Tuesday in a 3-0 loss to Nicaragua at the Pan American Games.

	U.S. reliever Huston Street couldn't help the team past Nicaragua. Team USA is now 3-1.

The team took the field only 10 hours after an emotional victory over the Dominican Republic, and the Americans' bats lacked the spark that had helped these collegians to an undefeated record this summer. They managed only four hits against Nicaragua, which is 3-0 and no-hit Guatemala the previous day. The U.S. team is 3-1.

"Olman Rostran pitched a tremendous game for Nicaragua,'' U.S. coach Ray Tanner of South Carolina said. "He kept us off balance offensively and their team made great plays behind him. They were the better team today.

"We are disappointed, but I am proud of our guys' streak and the way they've approached the game. We just have to regroup and get ready to play the next game.''

On Monday night, Jered Weaver allowed just one hit in 7 1-3 innings as the United States beat the host country 2-0.

"I knew that it would be a tough game, the Dominicans are always tough,'' Weaver said after the combined two-hitter. "When you have 20,000 people screaming against you, you can't beat it.''

Weaver silenced the fans and the Dominican Republic's bats, striking out four. But it was the Americans who couldn't mount an offense the next day.

"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.

"To make a ... comeback, I'm not sure if I*ve ever seen it, let alone done it,'' he said. "There's nothing like winning a team event. I*m just so psyched I could step up and help the team.''

Also celebrating were Cuba's Eric Lopez and Chellsie Memmel of Plano, Texas, 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, of West Allis, Wis., 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.

"I definitely did better than I expected,'' she said. "It was just an amazing meet.''

Teammate Nastia Liukin, 13, of Plano, Texas, won the balance beam, with Memmel getting bronze. Tia Orlando of Macungie, Pa., the last performer, won the floor exercise.

Through four days, the United States leads with 22 gold medals and 47 overall. Cuba has 18 gold and 32 overall.

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.''

In women's freestyle wrestling, the U.S. team made it 4-for-4. The gold medalists were three wrestlers from Colorado Springs -- Patricia Miranda at 105 pounds, Tina George at 121, and Sara McMann at 138 -- and Toccara Montgomery of Cleveland won at 158{.

"Our girls are really honed,'' coach Tricia Saunders said. "I am not surprised we did this.''

Hardly surprising was Lisa Fernandez's one-hitter with eight strikeouts as the U.S. women blanked Cuba 9-0 in softball. The Americans, who scored five runs in the first inning, have won every Pan Ams and Olympics since softball has been played.

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).

"We are a lot more comfortable as a team now,'' coach Debbie Ryan said. "Everyone seems more in rhythm. We've gotten better defensively each game.''

The world champion U.S. women beat Brazil 9-4 in water polo, but the win didn't impress their coach.

"This was absolutely the worst game we've played all year,'' Guy Baker said. "Our approach was poor, our execution was poor, our concentration was poor. If we keep playing this way, we're sure to pick up bad habits. Then you're just rolling the dice with your finish.''

Two more U.S. gold medals came in track and field.

Reese Hoffa of Athens, Ga., set a games record with a shot put of 68 feet, 3-4 inches. Then Aretha Hill won the women's discus at 207-8.

Defending champion Dawn Ellerbe of Columbia, S.C., finished fifth in the hammer throw at 215-8. Gold medalist Yipsi Moreno of Cuba broke Ellerbe's games record with a personal best 243-7, third in the world this year.

Lacking the emotion that carried them to a 2-0 baseball victory over the Dominican Republic and its 13 former major leaguers, the Americans had no offense against Nicaragua. That's not been unusual here: Nicaragua's Cairo Murillo no-hit Guatemala on Monday.

"We are disappointed,'' manager Ray Tanner of South Carolina said, "but I am proud of our guys' streak and the way they've approached the game.''

Cuba's vaunted team won't go undefeated either after Mexico beat it 7-1 Tuesday night.

Carly Gullickson, who became the youngest American to play tennis in the Pan Ams when she won Monday, beat Alana Broderick of Jamaica 6-4, 3-6, 6-0 in her second match. The 16-year-old from Palm Beach Gardens, Fla., led a perfect day by the six Americans entered.
