DUBLIN, OHIO ? Tiger Woods’ dominance at the Memorial suffered a setback Thursday. Not only was he nine strokes behind Bob Tway, he couldn’t even beat Jack.

While Tway birdied four of his first five holes and had a tap-in eagle for a 7-under 65, Woods failed to break par in the opening round for the first time all year. He three-putted for double bogey on the final hole for a 74 and was so angry he refused to talk about it.

A victory this week would make Woods the first player in 75 years to win the same tournament four years in a row.

Still, the cheers on a day of rare sunshine at Muirfield Village Golf Club belonged to Jack Nicklaus, the 62-year-old whose back has bothered him so much that he almost didn’t play in his own tournament for the first time.

“Obviously, it was a heck of a lot of fun,” Nicklaus said after birdieing four of his last five holes for a 1-under 71, the first time he has broken par at the Memorial in five years.

Tway, the former PGA champion who hasn’t won on the PGA Tour since 1995, rolled in two long putts to start his round and surged ahead on No. 15 with a 5-wood that stopped just 14 inches behind the cup.

He was one stroke ahead of Stewart Cink, who shot 66. Stuart Appleby was another stroke behind at 67.
