They wrangle over scores in rhythmic gymnastics, too.
Upset with marks given to American Mary Sanders in qualifying yesterday, the U.S. team filed an inquiry with the International Gymnastics Federation seeking a review of her hoop routine.
Sanders finished 18th out of 24 gymnasts in the first of two qualifying rounds. The top 10 gymnasts after today's second round will advance to the final. Sanders received a technical score -- the measure of difficulty -- of 4.6 in hoop.
The 4.6 was lower than anyone in the field except for competitors from Australia, South Africa and Cape Verde. The technical score is one of three elements judged in a rhythmic routine. The others are artistic value and execution. All have a maximum value of 10. Sanders's score in the other two elements was more in line with the other competitors.
"We don't know why the score was so low," American rhythmic program director Jan Exner said. "If there had been an obvious error in her routine, we would not have inquired, but there was not. We felt it was the prudent thing to do."
USA Gymnastics spokesman Brian Eaton said the inquiry was filed before scores were made official and that FIG was reviewing it. FIG spokesman Philippe Silacci did not immediately return messages left by the Associated Press.
The move by the Americans adds to a rash of complaints and protests that took place during the artistic gymnastics competition, which ended Monday. There have also been protests in equestrian, swimming, boxing, rowing and fencing at these Olympics.
Favorites almost always take gold in rhythmic, unless something unusual happens.
In the last Olympics, Alina Kabaeva of Russia was supposed to win gold, but her hoop went skittering out of bounds. The mistake couldn't be overlooked, and she won bronze.
Kabaeva came into these Olympics as the defending world champion -- a favorite again -- and she was in first after the first two rotations with 53.3 points despite dropping the hoop again.
"I feel pretty well, but I'll be able to say more" after finals, Kabaeva said.
Just behind Kabaeva were Irina Tchachina and Anna Bessonova of Ukraine. Those two finished second and third at worlds last year.
In team competition, Russia and Italy led the eight teams who will move onto the final.
World Cup champion Germany settled for bronze, beating Sweden, 1-0, on Renate Lingor's goal and a spectacular game from goalkeeper Silke Rottenberg in her 100th international appearance.
Rottenberg's milestone was commemorated with flowers and a pennant from FIFA President Sepp Blatter before kickoff, and the 34-year-old German remained the star during the game with three tough saves in a two-minute span in the first half and two more great stops after halftime.
Germany also won the bronze four years ago in Sydney.
The Swedes can blame their fourth-place finish on a lack of offense; they scored just four goals in five games.
Resilient Russia advanced to another gold medal game, and will take on a China team that ended Cuba's streak of three straight Olympic championships.
Hao Yang killed four of her team's last five points in the fifth set and finished with 23 points for the Chinese, whose powerful attack was ultimately too much for Cuba in a 25-22, 25-20, 17-25, 23-25, 15-10 victory.
On match point, Hao wound up and whacked a powerful spike from the left side that bounced off the arms of Liana Mesa Luaces and sailed out of the court. The Chinese players hugged and cried at the thought of returning Saturday to play for their country's first gold medal in that sport since 1984.
They will face a Russian team that dropped its first two sets and trailed in each of the last three before coming back to beat Brazil, 18-25, 21-25, 25-22, 28-26, 16-14.
Ekaterina Gamova scored 32 points to lead the Russians against a frazzled Brazilian team that blew a 24-19 lead in the fourth set and wasted a total of seven match points.
"Even when we fell behind, we had faith in ourselves and we knew that we would be the winners," Gamova said through an interpreter.
The Brazilians were winning by overshadowing the imposing Russian block with an impressive one of their own. Russia is the tournament leader in defense at the net, averaging just under three blocks per set, and Brazil beat them in that category, 20-12.
Brazil consistently aligned two or three defenders in perfect spots to stop the 6-foot-8 Gamova's long, high swing.
The quick, efficient offense the Brazilians are known for deserted them when it counted. Five of Russia's last eight points in the fourth set came on hitting errors by Brazil.
After taking a 13-10 lead in the fifth set, the Brazilians let the Russians climb back to tie it at 14. A ball hit by Virna Dias was blocked by Marina Sheshenina, and Marianne Steinbrecher's spike landed long to give the Russia the win.
Stern Russian coach Nikolai Karpol even managed to crack a smile, while a disconsolate Dias hugged friends in the Brazilian fan section for several minutes.
For the third straight Summer Games, the Brazilians -- the only unbeaten team in the preliminary round -- head to the third-place match.
"We had our chances," middle blocker Valeska Menezes said. "Unfortunately the ball kept stopping on the net, and we could not earn the points we needed."
Egypt's Karam Gaber threw around Ramaz Nozadze of Georgia, beating him, 12-2, for the gold at 2111/2 pounds (96kg). Gaber's gold is Egypt's first since two weightlifters won in London in 1948 and its first wrestling medal since 1960.
South Korea's Jung Ji Hyun completed a rapid ascension to gold medalist by beating Cuba's Roberto Monzon, 3-0, at 132 pounds (60kg).
Uzbekistan's Alexander Dokturishivili won at 163 pounds (74kg), beating Finland's Marko Yli-Hannuksela, 4-1, after eliminating 2000 Olympic champion Varteres Samourgachev of Russia in the semifinals.
Women's Field Hockey
Franziska Gude scored in the 20th minute, leading Germany to a 2-1 victory over the Netherlands in the first all-European final since 1992.
Luciana Paula Aymar scored with less than a minute remaining to lift Argentina over China, 1-0, in the bronze medal match.
Shih Hsin Chen got Taiwan's first gold medal by winning her 108-pound (49kg) match. About 15 minutes later, Mu Yen Chu added another.
Chen beat Yanelis Yuliet Labrada of Cuba, 5-4, in the final. Chu won his gold in the 1271/2-pound (58kg) division by beating Oscar Francisco Salazar of Mexico, 5-1.
