Luke Donald was two shots off the lead and Tiger Woods completed his first bogey-free round since returning to golf.

Donald and Woods were competing on day two of the Deutsche Bank Championship in Boston on Saturday.

Donald fired five birdies in a four-under-par 67 for a 10-under total, within striking range of 36-hole leaders Brandt Snedeker and Jason Day, who are 12 under for their two rounds.

Donald's display bodes well for next month's Ryder Cup, which could see him face Woods if the world number one earns a wild card spot in the United States team on Tuesday.

After a succession of poor showings since ending his self-imposed exile from the game, Woods may just be rediscovering some semblance of form in the nick of time to make the team for Celtic Manor.

"I figure if I play two good rounds and win the tournament, I should be all right," Woods said after shooting a six-under 65, one of the best rounds of the day, to move five under overall.

"I'm still learning to put this thing together. I'm going to have off days."

Woods is the defending champion of the FedExCup play-off series, of which this event is the second part.

He was not the only big name to score low today, 24 hours after the tournament felt some of the force of Hurricane Earl.

Phil Mickelson sunk two monster birdies in a six-under 65 - his lowest round of the year - to to move to eight under overall.
