FARMINGDALE, N.Y. -- So, that was a little strange.

Tiger Woods, in his first competitive round since winning the Masters, opened his PGA Championship with a roller-coaster ride of a first round Thursday. There were birdies and bogeys, doubles and eagles.

"It wasn't as clean as I'd like to have it, for sure," Woods said.

His day started early, at 8:24 a.m. local time off the remote 10th tee at Bethpage Black. Alongside defending champion Brooks Koepka and Open champion Francesco Molinari, Woods showed some rust and life, oscillating all day between bad Tiger and good Tiger.

Here's how the day played out, how Woods shot 72 and how he stands nine behind Koepka, who put on a show here Thursday:

No. 10: Par 4, 502 yards

Score: Double-bogey

Total for the day: 2 over

ESPN.com As Tiger Woods gets set to start his U.S. Open, it's worth noting his history of easing into major championships. With so many players under par -- including big names like Fowler and McIlroy -- he might not have that luxury this year at Pebble Beach. Needs a red number out of the gate if he's going to be a factor.

Woods: "Didn't get off to a very good start. It was a good drive and ended up in a bad spot, and I compounded the problem with trying to use the backboard behind the hole there and missing a putt I should have made."

No. 11: Par 4, 435 yards

Score: Par

Total for the day: 2 over

ESPN.com Tiger made things a bit more simple on No. 11, his second hole of the day. Fairway, green, two putts, move on. Nothing like the all-over-the-place double to start his day.

Score: Par

Total for the day: 2 over

Score: Par

Total for the day: 2 over

ESPN.com After he won the Masters, Tiger talked about always trusting his hands with feel shots. Well, they are betraying him early at Bethpage. In four holes, he's already twice missed the green from inside 90 yards. He salvaged par at 13, but that was a birdie chance wasted.

Score: Par

Total for the day: 2 over

ESPN.com Tiger with a steady diet of 30-footers over the first few holes -- that is when he hits the green in regulation. This leads to another par at No. 14 to stay 2 over.

Score: Birdie

Total for the day: 1 over

Score: Par

Total for the day: 1 over

Score: Double-bogey

Total for the day: 3 over

ESPN.com That's one annoyed Tiger Woods walking off the 17th green. His tee shot, short and in the bunker, buried itself. An awkward stance, an awkward swing results in a 30-footer for par.

Score: Par

Total for the day: 3 over

Score: Birdie

Total for the day: 2 over

ESPN.com The up-and-down day for Tiger continues. He rolls in a 14-footer for birdie at No. 1.

Woods: "Well, I felt like I was getting back into the round. I fought my way back and I had two double-bogeys in through there and was still able to get it to under par for the day. Unfortunately I had a couple three-putts there and hit a bad chip there at 8 and left myself in a bad spot."

Score: Par

Total for the day: 2-over 72

ESPN.com Tiger will be disappointed with that round of 2-over 72. Wasted a ton of shots. And even worse, for him, he watched as playing partner Brooks Koepka birdied the 18th to shoot a flawless 63.

Woods: "We'll see how it dries out over the next few days. I don't see them cutting the rough down, so it's just going to place another premium on driving the ball in the fairway to get at some of these flags."
