INDIANAPOLIS -- Turkey and Russia came into the World Championships considered as teams that could challenge for a medal. They kept that a possibility Saturday by winning for the first time and advancing to the second round.

Turkey, which had lost its first two games by a combined five points, beat Lebanon 107-80 and Russia, which hadn't looked impressive at all in its first two games, beat Venezuela 86-69.

Now Turkey, the European Championships runner-up and in this event for the first time, and Russia, which finished second in the past two World Championships, still have a chance to prove the experts right.

''Even with the two losses, and they were stupid losses, we kept our heads up and looked ahead and made the second round,'' said Hedo Turkoglu, who had 13 points for Turkey against Lebanon. ''We had to win one game to become ourselves and I just know we'll play better in the second round.''

Russia coach Stanislav Eremine had similar thoughts about his team.

''After losing two games, it was important psychologically to play well this time,'' he said. ''This time, all the guys were tuned into the game. I hope this victory will give us more inspiration the next time.''

In other games Saturday, it was: United States 84, China 65; Yugoslavia 87, Canada 71; Spain 88, Angola 55; Germany 102, Algeria 70; Argentina 112, New Zealand 85; and Brazil 90, Puerto Rico 86.

The top three teams from each four-team pool advanced to the second round. Yugoslavia and Spain had already clinched their second-round berths before Saturday's games, as had the United States, Brazil, Puerto Rico, Argentina and New Zealand. Angola advanced when Canada lost Saturday, and Germany and China moved on with Germany's win.

The four teams eliminated will play in a classification round to determine 13th through 16th place.

Turkey 107, Lebanon 80
Turkey's starting front line dominated in the big victory.

Mehmet Okur, who signed with the Detroit Pistons earlier this month, had 27 points and eight rebounds, while fellow forward Turkoglu, who plays for the Sacramento Kings, had five rebounds.

Center Huseiyn Besok added 17 points and 13 rebounds for Turkey (1-2), which had the close defeats to Puerto Rico and Brazil, the latter when it blew a four-point lead with 28 seconds left and lost on a 3-pointer at the buzzer.

''We could have gotten to the second round in a better situation,'' Turkey coach Aydin Ors said, ''but I believe it won't be easy to beat us in any of the game.''

Once again, the Turkish fans dominated Conseco Fieldhouse and when the game ended thousands of fans dressed in red and white and the team headed for a downtown ''Turkeyfest.''

''We are just trying to keep them happy,'' Turkoglu said with a laugh, referring to the fans who have become the talk of the tournament.

Fady El Khatib had 28 points for Lebanon (0-3), which is also making its first appearance in the World Championships.

Russia 86, Venezuela 69
Andrei Kirilenko, who plays for the Utah Jazz, scored 24 points for Russia (1-2), which broke the game open in the third quarter.

Russia was the runner-up to the United States in 1994 and to Yugoslavia in 1998. Kirilenko said past success might have been a factor in the bad start to this tournament.

''The level of world basketball is very high. Our game against New Zealand was proof our attitude has to change,'' he said. ''Destiny gave us this victory and a new chance. This victory gives us the opportunity to play with much more energy. Now we're feeling the taste of victory.''

Victor Diaz led Venezuela (0-3) with 27 points, while Richard Lugo added 18 points and 16 rebounds.

Yugoslavia 87, Canada 71
Peja Stojakovic had 23 points and 10 rebounds to lead Yugoslavia (2-1), the defending champions and winners of a record four world titles. Yugoslavia bounced back from a 71-69 defeat against Spain by taking control against Canada with a 12-0 run to open the second half.

Rowan Barrett, who played at St. John's, and Michael Meeks, who played for the Los Angeles Lakers, each had 18 points for Canada.

This is Canada's 12th appearance in the World Championships and though it has never won a medal, this will be the first time it doesn't finish among the top 12 teams.

Spain 88, Angola 55
Felipe Reyes scored 19 points and Pao Gasol, the NBA's rookie of the year last season with Memphis, added 16 for Spain (3-0).

Joaquim Gomez, who plays at Valparaiso, had 24 points for Angola (1-2), which advanced to the second round for the first time.

Germany 102, Algeria 70
Dirk Nowitzki scored 11 of his 24 points in the first quarter and Germany (2-1) advanced to the second round. Nowitzki, who plays for the Dallas Mavericks, played just 27 minutes and all 12 players on the German team saw at least nine minutes in the game and they all scored.

Milcud Doubal scored 16 points for Algeria (0-3), which is making it first appearance in the World Championships and failed to advance to the second round.

Argentina 112, New Zealand 85
Emanuel Ginobili, who signed last month with the San Antonio Spurs, scored 24 points, nine during an 11-0 run at the start of the fourth quarter that gave Argentina (3-0) an 83-72 lead.

Pero Cameron had 21 points for New Zealand (2-1), which advanced past the first round for the first time.

Brazil 90, Puerto Rico 86
Guilherme Giovannoni's 3-pointer with 1:29 left gave Brazil (3-0) the lead for good and it prevailed in the 3-point shootout. Giovannoni's 3 was the 14th of the game for Brazil and it gave it an 86-83 lead on the sixth lead change of the final quarter.

Marcel Machado, whose 3 at the buzzer gave Brazil an 88-86 victory over Turkey on Friday, was 6-for-9 from long range and finished with 23 points. Brazil was 14-for-23 from 3-point range for the game.

Elias Ayuso, whose 37 points against Lebanon on Friday were the most ever scored in a World Championships game by a player from Puerto Rico, was 9-for-13 from 3-point range against Brazil and finished with 31 points. Puerto Rico (2-1) was 11-for-25 on 3s for the game.
