ATLANTA -- Dustin Johnson had a reasonable lie in the rough and only a few pine tree branches blocking his path to the 17th green. Neither seemed like a problem until he played the wrong shot, clipped the tree and wound up with a double bogey Saturday in the Tour Championship.It was an example of how one hole can change everything at East Lake.And its why the final round of the PGA Tour season suddenly has more scenarios than Johnson cares to consider.Johnson recovered with a birdie from the bunker on the par-5 18th for a 1-under 69, giving him a share of the lead with Kevin Chappell (6 going into the last round that will determine who wins the Tour Championship and the FedEx Cup.For the first time since 2009, theres a chance it might not be the same player.Theres a lot of scenarios that could happen, Johnson said. But yeah, Im still going to go out and try to sht as low a score as possible.Johnson only has to win or finish second alone to claim the $10 million bonus as the FedEx Cup champion.Rory McIlroy, who has gone 28 holes without a bogey at East Lake, had three birdies over his last six holes for a 66 and was two shots behind. If he were to win the Tour Championship and Johnson finished in a two-way tie for second or worse, McIlroy would claim the FedEx Cup.It would just be great to try to win the Tour Championship, and if the chips fall my way, then so be it, McIlroy said.The winner of the Tour Championship has won the FedEx Cup every year since 2009, when Phil Mickelson won the tournament and Tiger Wds won the FedEx Cup.Johnson led by as many as four shots when he ran off three straight birdies on the front nine, and he really didnt do much wrong to give up the size of that lead. He had a three-putt from 70 feet on No. 13, and missed the fairway by a few feet on the next hole, enough that his ball was buried so deep that even Johnson and his power couldnt advance more than about 135 yards.It was the 17th hole that reshaped the tournament.Johnson tried to played a fade from a flyer lie in the rough, and the ball came out high and hit a branch, leaving him in more rough about 60 yards short of the green. He put that in the bunker, blasted out to 6 feet and missed the putt to make double bogey.Chappell rolled in a 10-ft birdie putt for a three-shot swing on the hole and suddenly had the lead, only for Johnson to catch him with the final birdie.They were at 8-under 202.Chappell, a runner-up three times this season who has never won on the PGA Tour, has made only one bogey in 54 holes this week, a show of consistency, discipline and a few gd breaks when he does miss the fairway.His next chance at a breakthrough victory is to face golfs best player at the moment (Johnson), with McIlroy and Ryan Mre (66) two shots behind.Ive always kind of been the underdog, so its a role Im comfortable in, Chappell said.Mre went out in 31 until he was slowed by a pair of bogeys, though very much in the mix just two shots out of the lead. The mystery is whether anything he does on Sunday -- even if that means a victory -- is enough for Davis Love III to use his last captains pick on Mre for the Ryder Cup.I came here this week to win a golf tournament, and Im 100 percent focused on that, Mre said, adding that the Ryder Cup is completely out of my control.And thats how the last day is shaping up for everyone -- post a score and see where it leads.Johnson, for a moment, lked as though he might take all the drama out of the season-ender when he made a 15-ft par putt early in his round and then ran off three straight birdies on the front nine to go four shots clear.The putter cled off, however, and Chappell stayed in range.Chappell chipped in on No. 12 to match birdies and stay three shots behind, and then he quickly closed the gap when Johnson made back-to-back bogeys, only to respond with a 4-iron over the water to a peninsula green on the par-3 15th to 15 feet for birdie.The 17th hole changed everything.I thought about just trying to hit it in the front bunker, which I probably should have done -- probably would have made 4 if Id have done that, Johnson said. But it is what it is. I came back and birdied the last hole, tied for the lead going into tomorrow. I like my position.And he doesnt need a degree in math to figure out the easiest scenario -- just win.Custom Lions T-shirts .

Cheap Custom Lions Jersey . - Goaltender Philippe Desrosiers of the Rimouski Oceanic has broken a shutout record that was only three months old in the Quebec Major Junior Hockey League.A marquee heavyweight matchup between former UFC title contenders Mark Hunt and Alistair Overeem will take place at UFC 209 on March 4 in Las Vegas.Both fighters have verbally agreed to the bout, according to UFC officials. The UFC 209 pay-per-view event will take place inside T-Mobile Arena.Hunt (12-10-1) has not fought since a decision loss to Brock Lesnar at UFC 200 on July 9. After that bout, it came to light Lesnar had failed multiple drug tests around the event, including one taken June 28.The positive tests showed the presence of clomiphene, an anti-estrogen. In documents submitted to the NSAC, Lesnar denied knowingly taking any banned substance.Lesnar was still able to compete because the result of the June test was not available to the UFC or Nevada State Athletic Commission until after the fight. He has since been suspended one year and fined $250,000. His win over Hunt was also changed to a no contest.Hunt, 42, was furious when results of Lesnars test became public. In October, he hired an attorney to demand a clause to his future UFC contracts that would call for stiffer penalties on opponents who fail a drug test. Representatives for Hunt were not immediately available to comment onn those demands.ddddddddddddSpeaking on his website, MarkHunt.TV, Hunt confirmed he is willing to accept the Overeem bout, but reiterated his demand for the additional clause to offer him protection in the event of another doping violation.My clause will protect me in this instance and take the financial gain of the opponent caught cheating, Hunt said. That deterrent will protect me and other fighters. Im pushing for this clause. I want to fight, and Im ready. If the fight doesnt go ahead, its not my doing.According to sources, Overeem has not agreed to any additional clause in the contract as of Tuesday night. The UFC has not yet commented on Hunts contractual demands.Overeem (41-15) is coming off a first-round knockout loss to Stipe Miocic in a heavyweight title fight at UFC 203 in September. Before the loss, Overeem had won four consecutive bouts.Hunt and Overeems fight at UFC 209 will be a rematch of a contest that tk place in Japanese promotion DREAM in 2008. Overeem won via submission in just 71 seconds.The UFC has not yet announced a main event for UFC 209. ' ' '
