CHERRY HILLS VILLAGE, Colo. — Rory McIlroy felt anything under par was a good score Thursday at Cherry Hills, even if he had reason to expect better.

McIlroy ran out of par saves late in the opening round at the BMW Championship and had to settle for a 3-under-par 67, still enough for the world’s No. 1 player to share the lead with Jordan Spieth and Gary Woodland.

Cherry Hills, one of the shortest courses on the PGA Tour when factoring in the mile-high air, held up just fine.

“It’s tricky. It really is,” McIlroy said. “The altitude, we’ve had a couple of days to adjust to that. It’s fine. But these greens have gotten so much firmer over the last 24 hours. I think that’s what is giving the guys just a little trouble out there.”

U.S. Open champion Martin Kaymer and Sergio Garcia were among those at 68, while Justin Rose wasted a fast start and was at 69. Phil Mickelson, who won the U.S. Amateur at Cherry Hills in 1990, opened with a 70.

McIlroy ran off four birdies in a five-hole stretch around the turn to reach 5-under. He appeared to escape trouble with one of his best par saves of the year, hitting a lofted pitch from the side of a mound that landed just on the green and rode the slope to about 8 feet. He avoided a three-putt on the next hole by making a 7-foot par save.

But that was the end of that. McIlroy failed to save par from the bunker on the next two holes.

Spieth also ran into his share of trouble, though he countered with six birdies and figured out the nasty combination of soft turf in front of the greens and putting surfaces that felt like they had been mixed with cement.

He blasted driver through the fairway on the 382-yard seventh hole because it offered the best angle into the green. The trick was playing the wedge. It came out low and running, something one would expect to see more in links golf, and it had just enough speed to crawl onto the green and settle a few feet away.

Woodland made only one mistake when he three-putted from about 50 feet on the fourth hole. He birdied both the par 5s, missing an 8-foot eagle attempt on No. 11, and was equally pleased with a par on the 18th hole, which features a severely canted fairway toward the lake and an uphill approach. Woodland hit 2-iron off the tee and a 6-iron onto the green.

Rain arrived late in the day and suspended the first round with nine players still on the course. They will return Friday morning before starting the second round. The field is only 69 players and there is no cut.
