Four birdies in a row from the sixth helped battling Padraig Harrington to move into the top-10 after the second round of the Honda Classic in Florida yesterday.

Harrington out in 32 went on to shoot a five-under-par 67 to trail clubhouse leader David Toms by four shots at the halfway mark.

Toms, playing with Harrington, dropped a shot at the last for a 67 to claim a one-shot lead over Billy Mayfair.

Lee Westwood and Luke Donald also produced thrilling bursts onto the leaderboard.

Three weeks after finishing fifth in the Nissan Open in Los Angeles Westwood added a superb 66 to his opening 73 and from joint 47th overnight even found himself out in front for a while.

Donald, meanwhile, played his last seven holes in a spectacular six under par for a 67 that put him alongside Westwood on five under.

And European interest did not end there. After a 65 Swede Daniel Chopra shared the early clubhouse lead with Australian Geoff Ogilvy on six under.

Westwood, seeking his first victory since 2003, turned in 33 with birdies at the 10th, 12th and 14th and then had three more in a row from the fifth. That was good, but what Donald did over the same stretch was even better.

The world number 14, second favourite for the title based on the rankings, followed birdies at the third, fourth and fifth with a 20-foot eagle putt on the next and then picked up another shot at the short eighth to be home in 30.

Last weekend Chopra was second with a round to go at the Ford Championship in Miami, but paired with Tiger Woods crashed to a 77 and 20th place. This week, though, David Toms is the only member of the world's top 10 taking part.

Ogilvy's round was almost as much a rollercoaster ride as his opening 67, which had included everything from an albatross - only the second on the US Tour this season - to a double bogey.

At seven under he was two clear of the field with four to play, but he double-bogeyed the par-three 15th, dropped another shot on the next after driving into a bunker and then jumped back into the joint lead by converting a nine-foot eagle putt at the 556-yard 17th.

That was the same hole the Adelaide golfer, winner of the World Matchplay title on his last start two weeks ago, had eagled in the first round.
