RIO DE JANEIRO -- Its no easy thing to push Usain Bolt, even in an Olympic warm-up race.It might be even tougher to upstage him.Some of Wednesday nights most entertaining theater came, as usual, from the Jamaican star, who smiled and wagged his finger at a brash up-and-comer while winning his 200-meter semifinals heat. Bolt will go for his eighth Olympic gold in the final on Thursday.Bolts main goal during the opening rounds is to conserve energy, which is exactly what he was doing when he looked to his right, saw Canadas Andre de Grasse a few steps behind him and put it on cruise control.The only problem was, de Grasse, the bronze medalist in the 100, didnt back down. He sped up, caught up and suddenly, the two were nose-to-nose, peering and smiling at each other down the stretch. Bolt finished in 19.78 to win by a scant .02 seconds. He wagged his finger at de Grasse as they crossed the line.That was really unnecessary, Bolt said. I dont know what he was trying to do. Hes a young kid. Hes great. He has a lot of talent. Im looking forward to the competition in the final.The competition wont include American Justin Gatlin, who has given Bolt more run for his money than anyone else over the past four years. In the evenings biggest stunner, Gatlin finished third in his heat and did not qualify for the final.He said he rolled an ankle in the run-up to the Olympics and was happy just to make it here.Probably, I should have rested it instead of running on it, said Gatlin, who finished second to Bolt in the 100.Team USAs Lashawn Merritt did qualify for the final. He finished first in his semifinal and third overall with a time of 19.94.Joining Gatlin (20.13) in failing to qualify was American Ameer Webb (20.43).Bolt, who has his eyes on not only the win but maybe another world record, is hoping his time will come Thursday night.I definitely think I can try for the world record, said the sprinter, whose current record in the 200 stands at 19.19 seconds. But now, its executing right, running the corner efficiently and coming in the straight and running the perfect race.The Associated Press contributed to this report. Erik Johnson Jersey . PAUL, Minn.

McCarthy, a player who played some games in the second tier for Wigan at the start of this season, would go on to shine inside Evertons midfield, outplaying the man he was brought in to replace, on one of the grandest stages in English football. On Saturday, it was fitting that Manchester Uniteds most recent dagger into the chest was delivered by Frenchman Yohan Cabaye, a wonderfully gifted central midfielder who put on an outstanding effort for Newcastle at Old Trafford. EDEN PRAIRIE, Minn. --?Minnesota Vikings quarterback Teddy Bridgewater, who threw for the first time on Tuesday after sitting out last Thursdays game against the Seattle Seahawks with a sore shoulder, said he expects to play in the teams third preseason game on Sunday against the San Diego Chargers.Bridgewater would not discuss how long he expected to play, whether he would throw deep passes in practice or the background of his injury, which ESPN reported on Friday. But he made it clear hes not worried about his health. I feel good, he said. I feel very good.The third-year quarterback did not throw a pass on Saturday or Sunday, and stuck mostly to short throws and passes over the middle in practice on Tuesday. His longest throw of the day was about 15 yards, and it was intercepted by Harrison Smith. Coach Mike Zimmer would not confirm or deny that Bridgewater had a shoulder issue on Tuesday, but said, If he had an issue with his shoulder, then Im going to make sure that I err on the side of caution. Sources told ESPN on Friday that Bridgewater would have played against the Seahawks had it been a regular season game.Offensive coordinator Norv Turner said the Vikings have not decided how long their starters will play on Sunday, in the teams first game at U.S. Bank Stadium. Were getting Teddy ready to play this week, and well see how tthe week goes, Turner said.dddddddddddd.The Vikings kept their first-team offense in for most of the first half on Thursday night in Seattle, sitting Bridgewater because of what Zimmer called a coachs decision and holding out Adrian Peterson, who hasnt played the preseason since 2013 and hasnt recorded a carry since 2011.Zimmer was mum Tuesday about whether Peterson would play Sunday, saying he didnt want to reveal to the Chargers whether the running back would be on the field for the third exhibition game. When a reporter pressed Zimmer on the idea that gaining a competitive advantage was worth being discrete about lineups in the preseason, Zimmer said, If they knew Adrian Peterson was playing in the backfield, I think they would probably be having a lot of run blitzes and a lot of eight-man boxes and stacking the line of scrimmage. When the reporter then suggested the Vikings would want Peterson to play against such a front, given what hed likely see in the regular season, Zimmer said, Well, well see in the game.On Wednesday, while Turner was talking, Zimmer walked behind the back of the offensive coordinators news conference and said, Hey, is Adrian playing this week? Is there a competitive advantage? ' ' '
