JERSEY CITY, N.J. — Liberty National was never so susceptible to low scoring as it was Thursday, and Tiger Woods could feel it. He just couldn’t do much about it.

Two hours into his opening round, Woods already was eight shots behind, and the gap only got wider. When his 12-foot par putt on his final hole stayed left of the cup, Woods had a 4-over 75. It was his second-worst score in 89 rounds of the FedEx Cup playoffs, left him 13 shots behind Troy Merritt and put him in danger of missing the cut at The Northern Trust.

“It just feels frustrating to shoot anything high no matter how I feel,” Woods said. “We had the early tee time. We had the perfect greens and had to go out there shoot something under par and get it going. Had to be 4-, 5-, 6-under par today. I went the other way with it.”

Of the 60 players who played in the morning, 39 broke par. Only one player, Patrick Rodgers at 76, had a higher score than Woods.

Expectations were not as high as usual for Woods, even on a Liberty National course where he was a runner-up in his two previous appearances. This was only his third competitive round since the U.S. Open, and he felt enough stiffness in his back during the pro-am that he only chipped and putted on the back nine.

He said his back was a little stiff Thursday, but that’s becoming the new normal.

And it was clear early that would be an issue.

He tugged a wedge into a lie so buried in the sand left of the 12th green — his third hole of the round — that he could only blast it out away from the flag. It kept rolling into a bunker on the other side, and he had to get up-and-down for bogey.

After a two-putt birdie on the 13th, his round fell apart.

Woods tried to hit a flat 9-iron on the par-3 14th, the signature hole at Liberty National with a view of the Statue of Liberty and the Manhattan skyline behind her. He pulled it over the flag, over the green and into a 5-foot ditch.
