“I need to win the Tour Championship in order to win the FedEx Cup,” Casey said. “For me, the most important thing is trying to focus on trying to win the Tour Championship and the FedEx is an amazing by-product of hopefully doing that.”Casey, who is looking for his second career USPGA Tour win, is at 12-under 198 in the final tournament of the PGA Tour’s 2017 playoffs.Kisner (64) and rookie Schauffele (65) are tied for second at 10-under 200.Tied for fourth at seven-under 203 is reigning PGA champion Justin Thomas (70), Patrick Reed (69) and US Open champion Brooks Koepka (68).Xander Schauffele of the US plays a shot during the third round of the TOUR Championship, at East Lake Golf Club in Atlanta, Georgia, on September 23, 2017 © GETTY/AFP / SAM GREENWOODCasey hasn’t won on the USPGA Tour in eight years but this season has been one of the most consistent finishers. If he follows through on Sunday he could win the tournament, the FedEx Cup title and the $10 million bonus that goes with it.Casey began the week in 10th place in the PGA Tour playoffs so not only would he need the victory on Sunday but several other pieces have to fall into place for that to happen.“I was just told the scenarios that could possibly happen and I said it’s all irrelevant if I don’t get the job done,” Casey said. “So, for me, focus on one thing. I can’t control what everybody else does.”He has finished in the top 10 eight times this season, with most of those coming in the second half of the season.“I had nothing to lose last week, and I have absolutely nothing to lose this week,” said Casey who also has six top-five finishes in his last eight FedEx Cup playoff events.Casey became a father for the second time September 11 but he has still not seen his baby daughter, Astaria, because he was preparing to play in the BMW Championship.If Casey does win the tournament and he will be showered with the combined $11.58 million jackpot which will buy a lot of baby gifts.Casey started quickly Saturday with two birdies and an eagle in his first six holes. He eagled the par-five sixth hole and curved in the 41-foot putt on the par-four 17 for a birdie, the fifth of his round.– On top –Kevin Kisner of the US plays his shot from the 11th tee during the third round of the TOUR Championship, at East Lake Golf Club in Atlanta, Georgia, on September 23, 2017 © GETTY/AFP / SAM GREENWOODCasey closed with an adventurous No. 18 where he had to get up and down. His approach landed short of the green in the rough then dribbled into a bunker. He tried to chip out but got too much sand and his ball found the rough again. He eventually chipped onto the green and then one-putted for par.His only real stumble was when he made back-to-back bogeys on number eight and nine.“A couple of blemishes on the card, but bounced back nicely and found the fairways, found the greens and put myself in there with chances,” he said.Top-seeded Jordan Spieth, who won the FedEx Cup two years ago, followed his 70 on Friday with a one-under 69 to reach a four-under 206 total.Spieth has his work cut out for him as he is tied for 13th with world number one Dustin Johnson (69), eight shots back of Casey.“Unfortunately, I’m not really in control of my own destiny at this point, but I’ll go out (Sunday), try and shoot a really solid round of golf and then do some cheerleading,” Spieth said.0Shares0000(Visited 1 times, 1 visits today) 0Shares0000Paul Casey of England plays a shot from a bunker on the 18th hole during the third round of the TOUR Championship, at East Lake Golf Club in Atlanta, Georgia, on September 23, 2017 © GETTY/AFP / Kevin C.
