Harrington finds form

Padraig Harrington shot his lowest round of the year to take a two-shot lead on the opening day of the World Golf Championships-Bridgestone Invitational in Ohio.

Seven days before he is due to defend his US PGA Championship title at Hazeltine National and following a year of disappointing results as the Irishman has sought to improve his swing, Harrington shot a six-under-par 64 at Firestone Country Club.
