(CNN) -- Luke Donald carded a sparkling eight-under-par 64 to take a three-stroke lead after the opening round of the Memorial tournament at the Muirfield Village Golf Club at Dublin, Ohio.
Donald's lowest score of the season gives him a three-stroke lead at the Memorial tournament.
The Briton started his round with a bogey at the first but a run of six birdies in seven holes on the back nine propelled him up the leaderboard ahead of Americans Jim Furyk and Ted Purdy, Australia's Jason Day and South Africa's Thomas Aiken, who all carded opening rounds of 67.
It was the lowest score of Donald's PGA Tour season so far and, having picked up eight shots in nine holes from the eighth, he told reporters: "Eight under through nine holes, that doesn't happen very often but when you get on that roll, it feels pretty good."
Purdy carded seven birdies but shipped a costly double bogey at the par three 12th, while Day finished with back-to-back bogeys.
Steve Marino, Stewart Cink and Mark Wilson sit tied for sixth on four-under-par, with a group of nine players, including world number one Tiger Woods, who has won the title three times, tied for ninth a further shot back.
Elsewhere, British Open champion Padraig Harrington struggled to a three-over-par 75 alongside Vijay Singh.
