Tiger Woods' purple patch showed no sign of abating as he surged to a first-round 66 at the Deutsche Bank Championship in Boston.
World number one Woods, 70 under par in winning his last four tournaments, is five under par going into the weekend.
He has a one-stroke lead over a group which includes England's Justin Rose.
Sweden's Carl Pettersson was unable to shine in his last-ditch attempt to impress Ryder Cup captain Ian Woosnam, only managing a five-over-par 76.
A bunker shot to five feet on the 543-yard last gave world number one Woods his one-stroke cushion.
"It was nice to get off to a quick start," Woods said. "I birdied the first hole. With the weather as windy and swirly as it was today, it was nice to be under par early and obviously under par after nine.
"And then the wind started dying down a little bit on the back nine, so you could be a little more aggressive on the back nine and go after some flags."
Only three players have won five consecutive PGA tournaments - Byron Nelson, Ben Hogan and Woods, who set the mark in 2000/2001.
Last year, Woods took a one-stroke lead after an opening 65 but ended up finishing 11 shots behind eventual winner Olin Brown.
Rose, 103rd on the PGA Tour money list, reached the turn in just 31 after birdies at the 10th, 14th, 17th and 18th, but although he picked up two more strokes on the front nine he also double-bogeyed the 5th.
"I made the most of the best part of the day," he said. "This morning there wasn't a lot of wind."
Londoner Brian Davis returned a two-under 69 and Ryder Cup Swede Robert Karlsson was on the same mark with three to play.
Pettersson, twice a winner in America in the past 12 months, would have been leading the points race if he had been a member of the European Tour from the start of qualifying, but is almost resigned to missing out.
England's Greg Owen had four bogeys in five holes in his 73 and is with Fredrik Jacobson of Sweden on two over.
