BRASILIA, Brazil -- Brazil started its quest for an Olympic gold medal in mens soccer with a disappointing 0-0 draw against South Africa, a result that prompted loud jeers by some of the home fans.Despite an attack led by Barcelona striker Neymar and talented youngsters Gabriel Jesus and Gabigol, Brazil was not able to find the net at the packed Mane Garrincha Stadium in Brasilia.Gabriel Jesus, newly signed by Manchester City, had the games best chance in the 69th minute but missed an open net with a close-range shot that struck the post.I have the obligation to score that goal, he said. Im not used to missing those chances. Im disappointed. I wont be able to sleep tonight because of that one.Neymar and Gabigol threatened a few times but also couldnt score.We had the best chances but the ball didnt go in, Brazil coach Rogerio Micale said. And we also have to give credit to South Africa, which has a very determined team and made it difficult for us to impose our game.South Africa played a man down from the 59th after defender Mothobi Mvala earned a second yellow card for a hard foul on Brazil right back Zeca.In the other Group A match in Brasilia, Iraq and Denmark also played to a scoreless draw, leaving all four teams tied.Brazil plays Iraq on Sunday, also in Brasilia, while South Africa faces Denmark.In Rio de Janeiro, Portugal defeated two-time Olympic champion Argentina 2-0 with goals by Paciencia in the 66th and Pite in the 84th in front of 45,000 fans at the Olympic Stadium, the vast majority cheering for Portugal. Earlier, Honduras defeated Algeria 3-2 in the other Group D game in Rio.In the jungle city of Manaus, Colombia and Sweden drew 2-2 in Group B.

South Africa, playing at the Olympics for the first time since 2000, also came close several times.The Olympics is Brazils first tournament since the senior team was embarrassed at the Copa America after failing to advance past the group stage of the continental competition. Neymar skipped that tournament to be able to play at the Rio Games.Brazil also finished second at the Olympic tournament in 1984 in Los Angeles and in 1988 in Seoul, the second time with a team that included Romario and Bebeto. The five-time World Cup champions won the bronze in 1996 in Atlanta with striker Ronaldo, and in 2008 in Beijing with playmaker Ronaldinho.South Africa defeated Brazil 3-1 in the group stage of the Sydney Olympics in 2000.

LEXINGTON, Ky. -- After playing in the bright lights and hype of the Champions Classic at New Yorks Madison Square Garden, a big question will be how No. 2 Kentucky responds to more subdued environment.The Wildcats return home fresh off their impressive 69-48 rout of No. 13 Michigan State and they will get their answers Sunday night against Duquesne.Great question, Kentucky associate head coach Kenny Payne said Friday. But we dont have to worry about that. The way that we coach, the way that we prepare those kids know that after that game is over, we celebrate. Its over. On to the next.The issue is outside of this environment. The friends. The parents. Their families. Now, they might talk to them about, Man, you all are the real deal. But when they walk in this gym and they walk in our offices, they know its on to the next. So they have no time to relax and feel good about anything. Were trying to get better.Payne explained it is part of the regular process in playing at Kentucky where everyone else is always trying to fast-forward to an NCAA championship.Its in everything we do every single day, Payne said. Were trying to get better every day. Are we happy we beat Michigan State thats a really good team? Yes, we are. Did we play our best? Not even close. Not even close.The top concern for coaches is rebounding. Kentucky was out rebounded 44-40 by Michigan State and 36-28 by Stephen F. Austin. UK did top Canisius 39-36.I think one of the things that has been a little disappointing with our athleticism, energy and length is that we havent dominated teams on the glass thus far, Payne said. Dont see that as a long-term problem, but its something that we have to focus on and get better at.In Duquesne, the 3-0 Wildcats will face a team that is 2-2 on the young season.dddddddddddd The Dukes defeated Loyola Maryland 65-60 and Saint Francis 89-75 but lost to Penn State 82-74 and Canisius 78-77 on Friday.We just need maturity and more time together, Duquesne coach Jim Ferry said. The biggest issue we have is the schedule. Were basically playing every other day. So weve not had the practice time we really needed. Our practices have been our games (leading to) making decisions on the fly.Duquesne is trying to restart after losing its top three scorers to graduation. Sophomore guard Tarin Smith leads the way at 15.5 points per game followed by freshman forward Isiaha Mike at 12.0. Darius Lewis, a 6-11 senior post player from Lexington, Ky., is the top rebounder at 6.5.Kentucky is averaging 83 points per game and has three players scoring in double figures, all guards. Sophomore Isaiah Briscoe is tops at 19.7 points per game followed by freshman Malik Monk at 16.3 and DeAaron Fox at 15.0.Freshman Bam Adebayo and sophomore Isaac Humphries share the rebounding lead at 5.7 per game.Monk is coming off his best game with a team-best 23 points against Michigan State during which he made 7-of-11 from 3-point range. In fact, it was the best overall game by Kentucky to date. To fend off any letdown, coaches make sure players are competing against themselves.They dont really know, and theyre learning, Payne said. For every one of these kids in this program, other than Isaiah Briscoe, everybody is still learning who they are as a player. There have been times when they havent been in dog fights before. So, theyre getting a chance to see. ' ' '
