Padraig Harrington goes into tonight's third round of the Deutsche Bank Championship in Boston just four strokes off the lead.

With his confidence growing by the day, the Dubliner continued his red-hot streak of form when he posted a four under par 67 to get to eight under par and share 11th place.

The reigning PGA Tour player of the year can still win the FedEx Cup and after six birdies and two bogeys he's well within striking distance of leaders Sean O'Hair and Jim Furyk.

O'Hair hit a seven under par 64 to join Furyk on 12 under with Tiger Woods seven off the pace after a battling second round 67.

Australia's Marc Leishman fired seven birdies and an eagle for a bogey-free 62 to lift him to third on 10 under with South African Retief Goosen, while John Senden, Scott Verplank, Justin Leonard, Dustin Johnson, Kevin Sutherland and Mike Weir are all bunched on nine under.
