AKRON, Ohio — Padraig Harrington broke par for the second straight day Friday, something he hasn't done in four months.

Without a victory since the PGA Championship, Harrington tread carefully across Firestone for a 1-under 69 that gave him a one-shot lead over Tim Clark (68) at the Bridgestone Invitational.

Tiger Woods, a six-time winner at Firestone, was among 20 players within five shots of the lead, although he found himself in a peculiar spot after an even-par 70. He was tied for 13th, the first time after any round at Firestone he had been out of the top 10.

He was at 2-under 138, the same score he had in 2007 when h ewon by eight.

Phil Mickelson, playing for the first time since his wife's surgery for breast cancer last month, made a few great escapes from the rough and put together a 69 to finish six shots behind Harrington.
