RIO DE JANEIRO -- Usain Bolt is leaving and insists hes not coming back.How will track and field ever be the same?The departure of the sports most electric athlete from the Olympics certainly makes the Tokyo Games feel like a less enticing prospect.Thats hardly the only issue track and field faces as it tries to clean up its act and find some new headliners before 2020.A look at what the sport might look like -- needs to look like? -- four years from now.---SPRINT GAMESomebody will have to claim center stage in the marquee events, the mens sprints. The early candidate is 21-year-old Andre de Grasse of Canada. As a teen, he ran one of his first races wearing basketball shorts and borrowed shoes. He stood up in the blocks while others crouched. It launched his career and led him to signing a big contract with Puma -- the same company that sponsors Bolt.In his own small way, de Grasse may have helped nudge the narrative of Bolts story in Rio a bit off line. His pushing of Bolt in the 200-meter semifinal -- probably unnecessary and maybe even a bit reckless -- made for the only real race the Jamaican faced all week.Bolt conceded that push-to-the-finish semifinal played into his inability to break his 200-meter world record a night later in the final. A small victory for de Grasse, even if it was a loss for everyone else.I was just happy to be part of history with him, said the Canadian, who finished second in the 200 final, and third in the 100. If people are talking about him, theyre probably talking about me, that I was in the same race.---STARS AND STRIPESAllyson Felix is 30. She has nine Olympic medals. Six are gold, a record for women on the track. After a long, hard season that didnt go the way she planned, she said Tokyo is nowhere in her thoughts.London, she said, speaking of next years world championships. Thats next on the agenda. As far as the next four years, taking it year by year.When Felix goes, who can step in as the next great female American track star? Heres a nod toward 400-meter hurdler Sydney McLaughlin, who made her first Olympics at 17. McLaughlin is the junior world-record holder in the event who really wasnt thinking about the Olympics this year.She made it to the semifinals at the Olympics. Now, its back for the start of her senior year of high school in New Jersey.---CRIME, DOPING, CORRUPTIONOnce the action got going, a lot of this sports troubles receded to the background. Still, the absence of the Russians could not be ignored. It was emblematic of a wide-scale doping crisis that has roots in the upper reaches of the International Association of Athletics Federations.President Sebastian Coe has taken over the organization, but there are still questions about what he knew, and when, while serving as vice president under Lamine Diack, who is accused of using blackmail to help perpetrate the Russian doping scandal.The IAAF banned Russia from the Olympics -- all but long jumper Darya Klishina, who lived and trained in the United States -- and many viewed that as a positive step, and one the International Olympic Committee was unwilling to take regarding the rest of the Russians.But the depths of the corruption in IAAF and Russia will continue to be exposed after the Olympics end. The IAAF is undergoing changes, including grappling with a proposal to handle drug testing independently. For the sports sake, this storyline needs to shift well before Tokyo.---RELAY MATTERSThe 32 medals the U.S. grabbed pretty much hit the mark that Duffy Mahoney, the chief of sport performance for USA Track and Field, predicted if the Russians didnt show.The U.S. won gold in three relays. Not bad. Oh, but that fourth one. The mens 4x100 team flamed out again with an illegal pass of the baton. The U.S. is medal-less in that event for the past three Olympics, hasnt won gold since 2000, and it cant all be blamed on the pressures of racing Bolt.There have been so many studies and working groups and practice plans for this team, and none of them really work.One suggestion: Find runners who want to make relays their top priority. Take a look at the program in Japan, which captured a silver medal Friday night.---A MODEST PROPOSALThe final scene of Bolt in action on the track came in the wee hours of Saturday morning. He was throwing a javelin. Think of the possibilities.Yes, he says his Olympic career is over, but also concedes his coach, Glen Mills, has told him not to rush into retirement.In the past, Bolt has talked about trying the long jump. More realistic -- how about a return to the 400 meters that was once tabbed as his second race, after the 200?He hates the training, but you could see a little gleam in his eyes after South Africas Wayde van Niekerk broke Michael Johnsons 17-year-old world record and set the mark at 43.03. Only two guys really ever had a chance to break that, Bolt said: van Niekerk, of course, and himself.Bolt turned 30 on Sunday. Hes got four or five decades of retired life ahead.What to do?I dont know, I dont know, he said. You just stressed me out. Cheap Nike Air Max China Wholesale .

After a lengthy wait, persistent rain finally forced the postponement of the Nationals game against the Miami Marlins on Saturday night. The teams, and a few thousand fans, waited nearly four hours from the 7:05 scheduled start time before an announcement was made shortly before 11 p. STORRS, Conn. -- Gabby Williams jumped early and totally whiffed the opening tipoff, eager to get a leg up on her taller Baylor opponent in the other half of the circle.If theres a metaphor for Williams play at UConn for the first two games of the season, that mistimed jump was it.The misstep will likely be a footnote after freshman Crystal Dangerfield scored 19 points to lead the third-ranked Huskies past No. 2 Baylor 72-61 on Thursday for their 77th consecutive victory. It is, however, characteristic of how Williams has started this season.The early minutes of the first two games have not been kind. Fresh off early foul trouble during UConns season-opening win against Florida State, Williams again found herself on the bench Thursday.She looked like she was well on her way to a big game early. The 5-foot-11 junior guard took a charge, had a monster block and hit a key bucket -- and then she picked up her second foul with 5:19 left in the first quarter, putting her on the bench for the rest of the half.I told myself I was never going to be in that position [in early foul trouble] again, and to be in it the next game was really frustrating for me, Williams said.While the Huskies are known for playing suffocating defense, discipline is another trademark. Huskies rarely foul out. But Williams wasnt the only UConn player in foul trouble. UConn finished tthe first half with Dangerfield, Kia Nurse, center Natalie Butler and freshmen Molly Bent and Kyla Irwin on the floor.dddddddddddd Thats not a typical lineup for the Huskies; they needed to reach deep into the bench to steer through the crisis.Our propensity to put ourselves in foul trouble these first two games is putting us in bad situations, UConn coach Geno Auriemma said. And we put ourselves in another bad one [tonight].UConn showed some mettle, though, putting four players in double figures and outdueling Baylors taller post players. Williams played all 20 minutes of the second half to finish with 14 points on 6-of-10 shooting, plus three assists, two blocks and two steals. She came up big when her team needed her most, making a huge steal with 2:15 left .For a lot of people, that [adversity] would affect them and shut them down, said Katie Lou Samuelson, who had 16 points. But she came out in the second half and was a huge spark for us. It was really important for her to do what she did. She took that charge and got our whole team really amped up.In the second half, Williams knew she had to play her game, but be smart and be clean, as she put it.I had to put mind over matter, she said. Im proud of how I came back. ' ' '
