OMAHA, Neb. It has never been so crowded at the top of the U.S. Senior Open leaderboard.
When Tom Lehman chipped in from 45 feet on the 18th hole Thursday, he joined six others at 3-under-par 67 to share the first-round lead at the Omaha Country Club.
The previous record was five co-leaders after the first round in 1997.
"In one round, 18 holes, it's like a sprint," Lehman said. "Over the course of four rounds, which is more like a marathon, things really do spread out."
Kenny Perry shot a 67 in the morning, putting together a solid start in his bid for a second straight win in a senior major. Michael Allen and Jay Don Blake also were 3 under after their morning rounds, and Gary Hallberg, Mark O'Meara, Fred Funk and Lehman had the same score in the afternoon.
The hilly 6,700-yard course took a toll on the field of golfers age 50 and older, especially in the afternoon as temperatures reached the upper 80s with a light breeze. The small and undulating greens browned up in the heat and proved dicey.
"When you get tough conditions and you're playing good, you get rewarded," Funk said. "More than likely, the guy that's playing the best in these kind of conditions will be at the top. Hopefully, it will be me."
Perry, who won the Senior Players Championship two weeks ago, made five birdies and two bogeys.
The season points leader started on the back nine and had birdies on three of his first eight holes. He hit an 8-iron to within 10 feet on the par-3 11th, drove the green on the 312-yard, par-4 13th, and hit a hybrid-pitching wedge on the 319-yard, par-4 17th and made his 15-foot putt.
He birdied both par 5s on his second nine but came away a bit disappointed after missing a 5-foot eagle putt on No. 6.
"I took care of the par 5s today and drove it nicely, kept it in the fairway, kept it in play," Perry said. "If I hit it in the fairway, I really like my chances on this golf course."
Lehman, the 2012 Champions Tour points and money leader, overcame a bogey on No. 8 with three birdies on the back nine none bigger than the one on 18. His second shot came to rest in thick grass to the right of the green. He used an 8-iron for his chip and watched it roll downhill slowly into the cup for the shot of the day.
"The lie was a little bit squirrely," Lehman said. "The grass was growing against the ball, so it's easy to kind of not catch it cleanly. I took less loft and kind of hit it a little bit thin. Once it gets out on the green, it's going to get down there."
Tom Watson, who played with Bernhard Langer (68) and Colin Montgomerie (69) and drew the largest galleries of the day, struggled with his irons while shooting a 70.
"I hit a few good shots today, but for the most part, my shots weren't very solid," said Watson, a Kansas City, Mo., native. "One good thing about it was that I got about the best score I possibly could out of my round."
Fred Couples, coming off three straight runner-up finishes on the Champions Tour, had a 71.
Couples, like others, had difficulty figuring out the speed of the greens. The recent heat wave has put stress on them, and warmer temperatures are forecast this weekend.
"They're suffering," Lehman said. "And there's differing kinds of grass. That's probably the biggest thing. It's not 100 percent pure. So the heat affects them each differently, which is why you see that spotty stuff. That kind of makes the putts really not quite as true as you would hope for."
PGA Tour in Silvis, Ill. Defending champion Zach Johnson shot a 7-under 64 and is tied with Camilo Villegas for the lead after the opening round of the John Deere Classic.
It was the 17th straight round in the 60s at TPC Deere Run for Johnson, who grew up roughly 100 miles away in Cedar Rapids, Iowa.
LPGA Tour in Waterloo, Ontario Angela Stanford and Catriona Matthew shot 8-under 63s to share the first-round lead at the Manulife Financial LPGA Classic.
Stanford closed her round in the late evening with three straight birdies to join Matthew atop the leaderboard.
European PGA in Inverness, Scotland Phil Mickelson, rebounding from a three-putt for a bogey on his first hole, shot a 6-under 66 to sit two strokes off John Parry's first-round lead.
