The only thing that spoiled John Cook's comeback was Fred Funk's finish.
Cook, who blew a big lead on the back nine at the British Senior Open on Sunday, carded a 4-under 66 at the U.S. Senior Open on Thursday, which was good for the clubhouse lead for most of the day until Funk birdied the 16th and 17th holes to go 6 under before three-putting the final hole and finishing at 5-under 65.
Funk had two birdies and an eagle on the first four holes of a spectacular round that was bogey-free until the 18th hole.
"Obviously, I got off to a ridiculously good start," Funk said. "It was a good day."
WGC: Retief Goosen, a late arrival and an early starter, took advantage of a Firestone South course that played long and short on his way to a 4-under 66 that gave him a one-shot lead at the Bridgestone Invitational in Akron, Ohio.
One year after Tiger Woods was the only player to break par, Goosen and 32 other players in the 80-man field met only minor resistance on a balmy afternoon at this World Golf Championship.
Vijay Singh and former Masters champion Zach Johnson were among those at 67, while Steve Stricker was headed for the outright lead until running into trouble off the tee late in his round, losing three shots in two holes and joining another large group at 68.
The length came from rain earlier in the week that softened Firestone and made it play every bit of its 7,400 yards. Tim Clark, a medium hitter who was at 67, hit his hybrid so often he was amazed it had any grooves left.
And the short? That would be the rough.
It was so deep last year that players often had trouble just getting it back to the fairway, and there were shots that squirted sideways leading to several big numbers. But the rough is only about 2 inches this year, at least giving players a chance.
PGA: Michelle Wie put herself in contention to make her first cut in eight tries on the PGA Tour, shooting a 1-over 73 in the opening round of the Legends Reno-Tahoe Open that left her eight strokes behind leader Jeff Overton.
Playing on the men's tour for the first time since January 2007, Wie had three birdies, four bogeys and rallied to save par on several holes at the 7,472-yard mountain course at Montreux Golf & Country Club on the edge of the Sierra Nevada.
