Milwaukee ? Brett Quigley wants to believe his father will be rooting for him to win his first PGA Tour event, even if it’s under his breath.

Paul Quigley is caddying for fellow Rhode Islander Brad Faxon this week at the U.S. Bank Championship, where his son is tied with Carlos Franco and Patrick Sheehan atop the leaderboard after 54 holes at 10-under 200.

“I hope his loyalty’s with me,” Brett Quigley said after carding the day’s best round at 6-under-par 64 Saturday. “I love Brad, and I hope he does well. But you never know.”

Defending champion Kenny Perry (65) is one shot back after birdies on the final four holes, and Jason Dufner (68) and Scott Verplank (67) are two shots behind the leaders. There are 22 golfers within five shots of the lead, and another five, including Faxon, are six shots back.

Growing up, Faxon caddied for Paul Quigley, whom he called Monday after getting back from the British Open, and asked to caddie for him at Brown Deer Park. Quigley’s father, in turn, called his son to see if he could room with him in Milwaukee.

Brett Quigley caddied for his dad three weeks ago in a qualifier for the U.S. Senior Open in St. Louis, where his father will either play — he’s an alternate — or caddie for his brother, Dana Quigley.

“There’s certainly a lot of caddies in my family,” Brett Quigley said.

And they’ll have quite a story to tell if Quigley can earn his first win on Tour.
