Were down to the final regular-season match of the year, and the stakes couldnt be higher. Andy Murray and Novak Djokovic will play in the championship match of the ATP World Tour Finals (ESPN2 & WatchESPN, Sunday, 1 p.m. ET) with the winner also snaring the year-end No. 1 ranking. This scenario has never happened.So who has the advantage? Hometown boy Murray or the much fresher Djokovic? Our writers weigh in.What does this match mean for mens tennis?Nic Atkin: Murray said it would be the perfect way to end the season, and I have to agree. While Im sure the crowd wouldnt have minded seeing Murray beat Nishikori in the final, any other matchup would have been a letdown.Peter Bodo: The match is a tribute to the quality and diversity of the field in mens tennis. It demonstrates how quickly the landscape can change, considering how far in front Djokovic was in the rankings as recently as June. It also validates the concept of a year-end final. Imagine the debate we would be having about the No. 1 ranking this year if the season had ended with the Paris Masters 1000. Now we will have a clear-cut answer.Greg Garber: This, as the U.S. president-elect would say, is huge. With Roger Federer and Rafael Nadal -- and Serena Williams, too -- all falling off their classic games, here are the two best-matched rivals in the game. One match for No. 1. It doesnt get any better than that.Johnette Howard: This is a rousing end to a mixed bag of a year in which Federer and Nadal were absent for long stretches. Even Djokovic -- the most reliable man in the game in recent years -- hit an unexpected trough. Given whats at stake here -- Murrays late-career chance to finally experience being No. 1 after years of never-say-die work versus Djokovics rallying to show he isnt giving up the top ranking without a fight -- this could be a memorable match.How will the pressure affect Murray?Atkin: There will be a lot of weight on Murrays shoulders. While he has overtaken Djokovic at the top of the rankings, he hasnt beaten the Serb on the way to No. 1 this year. Murray needs to show he is done playing second fiddle.Bodo: Murray has played his way into a zone where he probably wont be feeling much pressure at all, at least not the usual kind. Hes in a groove, playing lots of matches and winning them all, including two marathons this week. Murray will feel nervous, though, and he should. Nerves are just a sign that a players physical and neurological systems are going on high alert.Garber: I dont think pressure is the issue here. Against Raonic in the semifinals, Murray rose to the big occasion, again and again -- even saved a match point. I think the fact that hes played two three-hour-plus matches in a span of four days will be more telling.Howard: Playing in London agrees with Murray. He won Olympic gold there, not just Wimbledon. I think hell grouse, grimace, bluster and yell throughout. Hell play stretches of sensational tennis. But the match will not be over quickly. He will lose some games he shouldnt, especially if his legs are tired, and make it a nail-biter.What does Djokovic need to do to maintain his dominance against Murray?Atkin: Djokovic doesnt need to change anything physically. He will be far fresher than Murray. Djokovic just needs to make sure he keeps his cool and doesnt get wound up by the mental distractions that have plagued him in the second half of 2016.Bodo: The main themes for Djokovic should be consistency and serve efficiency. Murray still has lapses, struggles with his form and gets frustrated. Those can be exploited. Murray is returning very well and very aggressively. Djokovic needs to ramp up the efficiency of his own service game the way Murray has his these past few months.Garber: Play his crazy, all-court game. He looked ridiculously dominant against Nishikori, especially returning serve. Djokovic has won 16 of his past 19 matches against Murray, something the Scot will have a hard time discounting as he prepares for this.Howard: I think the three-set format favors Djokovic. He has the potential to win points quicker. Hes the better shot-maker and bigger risk-taker, whereas Murray is often risk-adverse and often gets worse when more is at stake. Djokovic has arguably the best service-return game in history, too, so if Murrays serve is off at all, hell find trouble.Who needs this win more?Atkin: Murray, for sure. If he loses, then doubt will still be at the back of his mind going into next season that his best still isnt good enough to beat Djokovic when the Serb is playing his best.Bodo: Djokovic needs to win this more because the rumors that hes lost something are growing louder and louder, while the chorus for Murray is all positive. Hes finally hitting his stride. Nobody is going to think Murray has dropped a level as a player if he loses this, but that will be the takeaway for most people if Djokovic does. Its especially true in light of Djokovics outstanding record at the O2.Garber: Its pretty much of a wash, but Ill say Djokovic. Murray has had a wonderful run, winning 22 consecutive matches, which matches his career high. Hell head into 2017 with a lot of optimism, regardless of the result. Djokovic needs this one to get back on track.Howard: Murray. Hes had to soldier on in the greatest era of mens tennis ever. Hes always been the junior partner in the Big Four and has always remained determined to chase Djokovic, Federer and Nadal, who all have double-digit major title totals. Murray has to know he may not get another chance to climb this mountain and be No. 1 again. So if not now, then when?Prediction?Atkin: Andy Murray ... in 3 hours, 39 minutes.Bodo: This week Murray has played two of the three longest three-set ATP matches of the year, and hell go into the final barely 24 hours after finishing the longest of those. So what? Andy is a juggernaut; mind over matter leads him to win in three.Garber: After Saturdays results, Djokovic in two.Howard: Murray in an upset squeaker. Djokovic rips another shirt.

EUGENE, Ore. -- Allyson Felix had the star power to change the Olympic schedule.Now, its her schedule that needs adjusting.Felixs run at the 200-400 Olympic double, made possible after Olympics officials honored her request for a chance to run both races, came to an earlier-than-expected end Sunday. She finished fourth in the 200-meter final, one spot out of the Rio mix, in a .01-second loss to a sprawling Jenna Prandini at the U.S. track and field trials.Honestly, disappointed, said Felix, who will not get a chance to defend her Olympic title in her signature event. The whole year, that has been what I was working for. When I look back and see everything that happened, I still think its quite amazing I was able to make the team.She did make the 400-meter lineup, and that is, indeed, quite an accomplishment considering the injury she suffered this spring. After landing awkwardly on an exercise ball while doing core work, she rolled her right ankle.The injury was so severe she avoided running around the track in the correct, counterclockwise direction until just before the trials, for fear shed put too much outside pressure on her injured ankle.In track lingo, a sprinter doesnt necessarily have to be fast to succeed in the 400 -- a full lap around the track in which technique is more important than pure speed. But in the 200, it takes a more aggressive lean into the curve at the opening of the race -- just the sort of practice Felix didnt get enough of during her slow comeback.I could only do what I could with the ankle, she said.And so, she started slow, never made up ground against winner Tori Bowie or second-place Deajah Stevens and could not hold off Prandini, the former University of Oregon star who had to wait about 30 seconds to see the result for third place go up on the board. Afterward, she was scraped up but smiling.I dont know what happeened, Prandini said.dddddddddddd But it got the job done.One of Felixs biggest fans made news earlier in the day: Sixteen-year-old Sydney McLaughlin became the youngest member of the U.S. Olympic track team since 1972 when she finished third in the 400-meter hurdles.Not bad for the junior out of Union Catholic High School in New Jersey, who tuned in to watch the Beijing Olympics eight years ago, saw Felix winning the 4x400 relay and thought, Id like to be like her, someday.Asked what she loved most about Felix, McLaughlin said: She wasnt afraid to lose.Sometimes, I get so caught up in the fact that I hadnt lost a hurdles race, and I come here, and these girls are faster than me, said McLaughlin, who admitted to being so nervous earlier in the week that she considered pulling out of the meet. Its realizing that sometimes you have to lose to get better.It happened to Felix plenty over the years, none more heartbreakingly than in Athens and Beijing, where she settled for back-to-back silvers in an event she had dominated.But she won gold in 2012.And with track and field -- and possibly NBC, as well -- desperate for some star power in a sport now headlined by Usain Bolt and a worldwide doping crisis, a scheduling change that would double the track time for one of Americas most popular runners was a no-brainer.But the U.S. trials dont guarantee anything, and on Sunday, a few more potential medal contenders -- including 400-meter hurdlers Johnny Dutch and Bershawn Jackson -- also saw some dreams end early.Felix is still going to Rio de Janeiro. But with more free time on her hands than originally planned.Im pretty sure everyone expected to see her on the  team, Bowie said. Im pretty sure it wont be the same without her. ' ' '
