Atlanta: Australian Adam Scott birdied the last two holes for a second consecutive day to break one stroke clear of a tightly bunched leaderboard at the season-ending Tour Championship on Friday.

The 31-year-old calmly rolled in putts from seven and 10 feet respectively at the 17th and the last to cap a sparkling five-under-par 65 in the second round at East Lake Golf Club.

"Great finish for the day," a smiling Scott told reporters after taking control of the PGA Tour's fourth and final playoff event on a hot and steamy afternoon when six players at one point held a share of the lead.

"I made a couple of nice putts on those [last two] holes. I've actually birdied them both days so far, so I'd like that trend to continue."

Champion here in 2006, Scott recorded eight birdies and three bogeys to post an eight-under total of 132 and stay on track for his ninth PGA Tour victory and FedExCup honours.

Three bogeys

"I'm very pleased with the way I brought it back and got myself in the tournament," said the Australian, who had sputtered with three bogeys in the first six holes. "I put it all together for the last 12 holes."

South Korean K.J. Choi was alone in second after carding a matching 65 while Australian Jason Day (67) and British world number one Luke Donald (68) were a further stroke back at six under.

"I was very happy with the score," said Donald, who is bidding for his second PGA Tour victory of the year. "I didn't hit the ball quite as solidly today, and I didn't quite have as much control as I did yesterday."
