Golf:Sean O'Hair fired a seven-under-par 64 to join overnight leader Jim Furyk at the top of the standings midway through the second day of the Deutsche Bank Championship.

American O'Hair set up his impressive round by picking up eight shots in as many holes. His run began with birdie at the par-four 15th and was highlighted by eagle at the par-five 2nd as he turned for home.

A dropped shot at the sixth blotted his copybook but it was enough to join Furyk, who shot a 67, as the clubhouse leader on 12 under.

Pádraig Harrington was also moving in the right direction and was three-under through 15 holes and seven-under for the tournament.

Tiger Woods was two-under through 13, three-under overall.

Marc Leishman made full use of the perfect conditions this morning to catapult himself into contention with a nine-under 62 - to leave him two strokes adrift of the leaders.

The Australian's faultless round included seven birdies and an eagle on the par-five 18th to lift him up from a tie for 48th overnight and into a share of third place with Retief Goosen.

Leishman was in red-hot form from the start of his round, blitzing his way to a 29 on the outward nine, and then when he birdied the first and second on the way home looked set to break the course record.

It was not to be as he could only make up one further stroke, on the par-five seventh, to fall a stroke short.

"It was scoring conditions, that's for sure," he said.

"It was getting out there really early on the smooth greens and no wind. It was low scoring conditions and I made the most of it, which was nice to do for a change."
