Round one to “The Monster.”

“It was a real beast today,” Ernie Els said.

Only seven players from the 156-man field were under par when darkness covered the course with 18 players unable to finish their round due to a 90-minute thunderstorm delay.

Sweden’s Robert Karlsson, the only player to crack the top 10 in all three of golf’s majors this year, and India’s Jeev Milkha Singh - not to be confused with two-time PGA champion Vijay Singh - each posted a 2-under-par 68 in pleasant morning conditions.

Argentina’s Andres Romero, the only player under par from the late starters, was at 2 under with two holes to play when the horn sounded.

“A great test of golf and patience,” Singh said.

It was too much of a test for Kenny Perry, who withdrew after a 79 because of an eye injury. Tiger Woods - sidelined for the rest of the year after knee surgery - won the U.S. Open on one good leg, but Perry didn’t stand much of a chance with one eye.

“It was annoying and difficult to be trying to fight a tough golf course and have the eye aggravating me at the same time,” said Perry, who will finish the year playing one round out of four majors.

Even playing with full vision was no picnic.

“There’s only one guy who’s going to like this place by the end of the week,” Ben Curtis said after he played bogey-free and led at 3 under through 10 holes, then lost six shots in the final eight holes for a 73.

The calendar says August. It sure seemed like June, with firm fairways, thick rough, hard greens and plenty of opinions.

The PGA looked a lot like the U.S. Open.

It sounded like it, too.

“The course is 7,500 yards long, the greens are firm and the pins are tucked away,” Lee Westwood said after finishing with six straight pars to salvage a 77. “They are sucking the fun out of the major championships when you set it up like that.

“I sound as if I’m moaning - which I am - but it’s a great shame. It’s a fantastic golf course. They are great greens and they are playable. But there is no need to play it as it is.”

Such comments typically are reserved for a U.S. Open, and the similarities didn’t stop there. The rough is so thick that players rarely reached the green after missing the fairway, and caution was required for every putt on greens that became so crispy in sunshine that officials hosed down three of them throughout the day.

Even so, the best golf was rewarded.

Sergio Garcia struck the ball as solidly as ever, holed one long putt, limited his mistakes and joined a group at 69 that included Billy Mayfair, Ryder Cup hopeful Sean O’Hair and Ken Duke.

Phil Mickelson, the 2005 PGA champion seeking his fourth major title, was in three bunkers before he reached his second green (No. 11), was 2 over for his round and somehow managed a 70. He made only eight pars, but among his five birdies was a 35-foot putt down the scary slope on the 16th, followed by a 4-iron that rolled within 18 inches for a birdie on the 238-yard 17th.

“I’m just happy to have shot even par today,” he said.

Anthony Kim overcame five bogeys with an eagle on the par-5 second hole that carried him to a 70, joining the likes of 2007 U.S. Open champion Angel Cabrera, Rod Pampling and Michael Allen, the last alternate into the field.

British Open champion Padraig Harrington birdied the first three holes but settled for a 71.

Karlsson opened his round with a shot that bounded off a cart path over the first green and led to a double bogey. He answered with three straight birdies and reached 4 under for his round until he missed the green for bogeys on 14 and 15 and settled for a 68.

How does someone start with a double bogey and not lose his cool, much less his mind?

“Try to remember that I actually can play golf, even though it didn’t look like that on the first hole,” Karlsson said. “My caddie said, ‘Remember, we played with Tiger in the U.S. Open.’ And I think he took 6 down the first hole pretty much every day. So you can shoot a good round from here as well.”

But such rounds were hard to find.

“It’s a U.S. Open at the moment,” said Geoff Ogilvy, who won the Open at Winged Foot in 2006 without breaking par in any round. He failed to do that Thursday with a 73. “This is one of the clubs that prides itself on how hard it is. I don’t think anyone expected it to be easy. It wouldn’t be a monster if it was.”

Ben Hogan gave Oakland Hills its nickname when he won the 1951 U.S. Open and said he was glad he brought “this monster” to its knees. “The Monster” played like it was on steroids, especially after Rees Jones lengthened it to just under 7,400 yards.

His redesign did not meet everyone’s approval.

“If you had Rees Jones redo ‘Scrabble,’ he’d leave out the vowels,” veteran Paul Goydos said after a 74.

Players knew what they were getting into after three days of practice. The surprise came when they got on the golf course Thursday and found it firmer than ever, with balls rolling on the fairway and crusty footprints visible on the greens. Mickelson hit what he thought was a perfect tee shot on No. 10 with a hybrid, only to learn that it rolled all the way into a bunker.

Karlsson, however, made six birdies. And the other Singh - Jeev plays the European tour - made only three bogeys on a course much harder than he had seen during practice.

His best birdie might have been a 3-iron to 20 feet on the 17th.

“To stop the ball on that green when there’s a lot of breeze from behind, that was good,” he said.

Singh fits the mold of someone who would thrive in the majors this year. He came to Oakland Hills with an ankle injury he has been coping with the last two months, so severe that doctors have recommended a month of rest.

Trevor Immelman won the Masters four months after having a benign tumor cut out of his back. Woods won the U.S. Open on one good leg. Harrington wasn’t sure he would be able to play - much less win - the British Open because of a wrist injury.

Singh said he had to be careful walking the hills on this course. The only time it really hurts during his swing is when he hits driver.

“And you do need to hit a lot of drivers on this golf course,” he said.

Vijay Singh, the more famous of the two, bogeyed his last two holes for a 76.

Jim Furyk is among those who like the course firm and fast, and he was satisfied with a 71 that put him in the group with Steve Stricker, who is No. 8 in the Ryder Cup standings.

The nightmare belonged to Hunter Mahan, who is 10th in the U.S. standings and was runner-up at Oakland Hills in the 2002 U.S. Amateur. He posted his highest score as a professional - an 81.
