Over the years there are certain pairings for me that I’ve enjoyed, and Rory is one of them.”Woods, a three-times winner on the PGA Tour this season, was paired with McIlroy for a fifth time in this year’s FedExCup playoffs, a perfect scenario for television ratings as well as for the East Lake fans."I think that is the whole idea of the playoffs, trying to get the top players all playing more often but also in the same group,” said world number two Woods, who won the Tour Championship in 1999 and 2007."You figure the top players are going to gravitate towards the top of the points list and hence, you’re going to have these types of pairings throughout the playoffs. And it’s turned out that way this year.  McIlroy, who has overshadowed Woods this season by winning four times, including his second major title at last month’s PGA Championship, relished playing again with the American former world number one."It was great,” the 23-year-old Northern Irishman said. "I always say with groupings like that, it’s a great atmosphere and it’s a great buzz. I wish I could have shot a couple of shots better.
