FORT WORTH, Texas — Ryan Palmer was standing in the fairway on his last hole Thursday when his longtime caddie and fellow Colonial member issued a challenge.

James Edmondson, who won his third Colonial club championship last year, told Palmer that a birdie would match the caddie’s low round at Hogan’s Alley.

“What do you do when you get that thrown at you,” Palmer said.

Palmer hit his approach to 5 feet at the 388-yard ninth hole for an 8-under-par 62 that matched the lowest PGA Tour first round at Colonial. That put him a stroke ahead of John Rollins, who had his best round this season.

For all the rounds Palmer has played at Colonial, where he has been a dues-paying member since 2010, he had never had such a low score. He generally plays there two or three times a week during the offseason and once or twice during weeks he’s not playing the PGA Tour.

“These old men here make me grind because I have to give them so many shots. Maybe that helps,” Palmer said, smiling.

Graham DeLaet, wearing pants with a plaid design similar to the jacket Colonial winners get, matched Morgan Hoffmann, David Hearn and John Peterson at 64. Matt Kuchar, the highest-ranked player (No. 13) in the 136-man field, was in a group of six players at 65.

Former Husky Richard H. Lee shot a 70. Kyle Stanley from Gig Harbor had a 74. Ryan Moore from Puyallup shot a 78.

Haas, Waldorf

lead Senior PGA

ST. LOUIS — Jay Haas and Duffy Waldorf shared the first-round lead in the Senior PGA Championship, shooting 5-under 66 in breezy, cool conditions at Bellerive Country Club.

The 59-year-old Haas, the winner of the major championship in 2006 and 2008, had a bogey-free round. The 50-year-old Waldorf had six birdies and one bogey.

Haas has 16 Champions Tour victories after winning nine times on the PGA Tour. Waldorf is winless in 11 career starts on the 50-and-over tour after winning four times on the PGA Tour.

Tom Watson shot a 69.

Kirk Triplett, a graduate of Pullman High School, shot a 70. Jeff Coston, a teaching pro from Blaine, had a 71.
