AUSTRALIAN Geoff Ogilvy declared himself "officially an athlete" after been drug-tested for the first time in his career.

After shooting a four-under-par 67 in the first round at the Deutsche Bank Championship in Boston, six strokes behind Canadian leader Mike Weir, Ogilvy was greeted outside the scoring trailer by a representative from the US PGA Tour's drug-testing body.

The tester accompanied Ogilvy to the locker room, filled out the paperwork then watched the 2006 US Open champion urinate in a cup, never letting the player out of his sight. Such a procedure, of course, is commonplace in other sports but is new to professional golf, which until recently had denied there was a problem even though it managerial bodies did not test its players.

"The peeing for me was instant, because I needed one, but the whole process, with the paperwork, was probably 15 minutes," Ogilvy said.

"He's standing in the cubicle when you're peeing in the beaker. He's making sure you're doing it, but it didn't feel invasive."

Ogilvy is a big fan of cycling and athletics, so he's not exactly naive regarding performance-enhancing drugs, but he doubts anyone on tour is on the juice.

"You're more likely to get guys testing positive for non-performance-enhancing drugs.

"We're not on the WADA [World Anti-Doping Agency] list. Our list is pretty fair. If they banned caffeine I'd be in trouble, but that's about it," he said.

On the US Tour eight players are randomly tested after each round, and Adam Scott was among others tested on Friday.

Weir, meanwhile, matched the Boston TPC course record with a 10-under 61, earning a three-stroke lead over a group including Fiji's Vijay Singh.

Weir had no great expectations of a great round, but made a confidence-boosting start with birdies at the first four holes and never looked back.

"There was no indication when I was warming up that it was going to be like that," said the 2003 Masters champion, who needed only 21 putts.

"It was just one of those days, where I made a 15-footer on the first hole and then another one on the second hole."

Ogilvy, equal 19th, headed the Australians.
