LOUISVILLE, Ky. — For Tiger Woods, there was a familiar complaint.

Yes, his back was hurting again.

His performance at the PGA Championship is becoming more the norm, as well.

Once the game’s most dominant player, Woods looked old and tired at Valhalla. He was surely overmatched Friday, shooting his second straight 3-over 74 to miss the cut at one of golf’s biggest events for only the fourth time in his professional career.

Not that this was a big surprise.

Woods was playing in only his fourth tournament since back surgery in late March, and he hasn’t been a factor in any of them. He failed to make the cut at the Quicken Loans National. He had his worst 72-hole showing in a major at the British Open. He had to withdraw on the final day of the World Golf Championship at Firestone after taking an awkward swing and hurting his back again. He showed up Wednesday at Valhalla, proclaimed himself fit – and flopped again.

“I tried as hard as I could. That’s about all I’ve got,” Woods said. “Unfortunately, I just didn’t play well. Consequently, a pair of 74s is not very good.”

With the cut at 1 over, Woods wasn’t even close to playing on the weekend.

He was effectively done after shooting a 4-over 39 on the front nine, including a double bogey at No. 6 – where he three-putted from 18 feet – and an ugly bogey at the par-5 seventh. He drove into a muddy bog far left of the fairway and had to punch out. He sailed his third shot over the green, and a sloppy chip came up short.

Woods played better on the back side – a couple birdies, a single bogey – but he was all done at that point.

He’ll likely have plenty of time to work on his game and build up his strength.

If he doesn’t play next week at the Wyndham Championship in Greensboro, North Carolina – and he never has – his season is over. Woods needed to win the PGA to qualify for the FedEx Cup playoffs.

It also seems highly unlikely that Woods will be one of the wild-card picks by U.S. Ryder Cup captain Tom Watson, who said over and over that he wanted to see some sign the 14-time major champion was rounding into form.

Instead, Woods can’t even beat the 64-year-old captain, finishing behind him at the British Open and three shots worse at the PGA.

“I felt like I wasn’t that far away when I came back at the Quicken Loans,” Woods said. “But obviously, the more I play, I can’t develop my strength while playing a lot. I need to get back in the gym and get stronger.”
