Ponte Vedra Beach, Fla. ? Tiger Woods and Adam Scott have such similar swings, it’s often tough to distinguish them. That was hardly the case Thursday in The Players Championship.

The 23-year-old Scott was in full flight, knocking down flags on his way to a 7-under 65 and a one-shot lead.

Woods continued to search for a swing he could trust, struggling to his fourth straight round over par, a 75 that put him in a tie for 108th and in serious jeopardy of missing the cut for the first time in six years.

Playing in the group ahead of the world’s No. 1 player, Scott showed the fans what they thought they might see from Woods. He made six of his birdies from inside 6 feet, closing out a superb round with a 9-iron into 3 feet.

Duffy Waldorf survived a wild finish to his round of 66 by making a 15-foot eagle putt on the 16th, dunking one in the water on the island-green 17th for double bogey, and closing out with a birdie from 10 feet.

Thomas Bjorn, K.J. Choi and Bon Burns shot 67s, and Ernie Els, Sergio Garcia, Scott Verplank, Padraig Harrington and Brandt Jobe opened with 68s. John Daly topped a group at 69, and Phil Mickelson and Vijah Singh were another stroke back at 70. Former Kansas University golfer Matt Gogel opened with an even-par 72.
