Rory McIlroy went the other way lamely signing for a +2 over par 72, which leaves him nine shots off the pace and languishing at T10.

At the other end of the scale Billy sunk a 32-foot birdie putt on the 18th Saturday to post a 7-under 63 and take a three-shot lead over Ryan Palmer in the BMW Championship, he spoke about the positives; "There were a lot more positives from last week to take than just one bad swing on the last hole. So, I knew coming in that I was going to play well." Ryan is not that far behind, scoring -3 under par 67 in his third round giving him a -10 under par tournament total; "Rory, he's No. 1 in the world, and Sergio has been up there for years, so, for me to come out and hang in there and play well, I'm taking the next step in my career, I think." Third place is shared by Martin Kaymer and Bubba Watson, both have -8 under par totals, but will have to go low tomorrow to catch the leader. Morgan Hoffman posted the low round of the day, a magnificent -8 under par 62, but can only boast a -4 under par total. Knowing he had to finish this week in the top three to make it to the Tour Championship next week, today he just went out and played golf, and at one point in the round was thinking of a 59; "I don't have anything to lose, so I was just trying to have some fun. It was possible with three more birdies coming in." "We were feeding off each other a bunch, we were joking around the whole day. Kind of just messing with each other, which is a lot of fun out there. It really helped our game." Morgan is actually just four shots out of third place. If he can go really low once more he could well make it to next week; "I'm going to be going low and being as aggressive as I can, there's no reason not to." Phil Mickelson withdrew from the BMW Championship, bringing to an end to his worst PGA Tour season in more than 10 years. He quit after two days so that he could rest up before the Ryder Cup; "My primary goal is to rest and prepare for the Ryder Cup. Without a chance to contend at the Tour Championship, the most important thing for me now is to prepare for the Ryder Cup."
