South Africa's Louis Oosthuizen was in the zone Sunday, stringing together seven straight birdies to jump out to a three-shot lead with only one round to play at the Deutsche Bank Championship.

Oosthuizen's incredible streak included going 19 consecutive holes without missing a green. He ended the par-5 18th with a birdie as well that gave him an 8-under 63 on the day. His total score of -19 is a new record through the first 54 holes of play.

Rory McIlroy was solid in his own right but the 23-year-old golfer's 4-under round wasn't enough to keep up with the sweet swinging Oosthuizen.

Dustin Johnson remains in striking distance, tied in third place with Tigers Woods at -13 under. Sunday marked Woods second straight round of 68.

The final round begins early Monday morning. For a complete listing of the leaderboard, visit the PGA's website.
