FORT WORTH, Texas (AP) - Tim Clark birdied the 18th hole for a 6-under 66 on Saturday that gave him a two-stroke lead going into the final round of the Crowne Plaza Invitational.
Clark moved ahead of playing partner Steve Stricker with a birdie on the 11th hole, then strung together pars until No. 18.
The South African was at 17-under 193 as he chased his first career PGA Tour victory. He's finished second six times, including this tournament last year, getting nipped when Phil Mickelson birdied the final hole.
Stricker, Steve Marino and Jason Day were at 195. Marino and Day are also seeking their first PGA Tour wins.
Marino was the day's big mover, shooting a 62 for the best round of the tournament so far.
