ATLANTA, Sept 21 (Reuters) - Henrik Stenson made yet another fast start then struggled in torrential rain over the closing holes to remain four strokes in front after Saturday's third round of the season-ending Tour Championship.
With the FedExCup playoff title and its bonus jackpot of $10 million also on the line at East Lake Golf Club, Stenson carded a one-under-par 69 in difficult scoring conditions to stay on track for all those honours.
The Swede, ranked second in the FedExCup points standings, raced to the turn in four-under 31 to briefly lead by nine strokes but dropped four shots on the back nine to post an 11-under total of 199.
Long-hitting Dustin Johnson, who narrowly squeezed into the elite field of 30 players, fired a 67 to sit alone in second place at seven under, two ahead of fellow American Steve Stricker (68).
FedExCup points leader Tiger Woods, seeking a sixth PGA Tour victory this season, was a distant 14 strokes off the pace after returning his first sub-par score this week, a 69. (Reporting by Mark Lamport-Stokes; Editing by Julian Linden)
