FORT WORTH, Texas — Ryan Palmer has a definite home-course advantage at the Colonial.

Palmer and his longtime caddie James Edmondson are both full-fledged members of the club, and play there quite often. Edmondson is even the reigning Colonial club champion, having won his third such title just last year.

Making good use of all that local knowledge, Palmer shot an 8-under 62 on Thursday that matched the lowest PGA Tour first round at Hogan’s Alley. That put him a stroke ahead of John Rollins, who had his best round this season.

“It’s pretty neat. A lot of fun,” Palmer said. “I don’t even pull out my yardage book except to fill out the scorecard. When I see the pins I can tell you, I know everything about the greens. It’s a matter of what’s the yardage, get the wind.”

Rollins, who like Palmer lives in nearby Colleyville, has playing privileges at Colonial like other PGA Tour players. He doesn’t play the 7,204-yard layout nearly as much as Palmer.
