England's Paul Casey stormed into pole position to celebrate the birth of his second child by winning the FedEx Cup title and USD10million (£7.4million) bonus after a rollercoaster third round of the Tour Championship.
Casey carded a superb 65 at East Lake to finish 12 under par, two shots ahead of Americans Kevin Kisner and Xander Schauffele in the season-ending event.
Any of the 30 players in the field can theoretically win the massive pay day, but only the top five in the FedEx Cup standings were assured of doing so by claiming the USD1.53million (£1.1million) first prize in Atlanta.
Open champion Jordan Spieth began the week with a 200-point lead over Justin Thomas, with world number one Dustin Johnson, Marc Leishman and Jon Rahm the other players in control of their own destiny.
Ranked 10th, Casey needed to win his first PGA Tour title since 2009 and for the top five to falter to claim the jackpot, a situation which initially looked unlikely, but moved a significant step closer on Saturday.
Playing partner Thomas is five shots behind after a 70, with Rahm a shot further back, Spieth and Johnson on four under and Leishman out of the picture on one over.
" My last round here last year was a 64 and I'd take a 64 tomorrow," Casey, who has yet to meet his baby daughter Astaria, told Sky Sports. " I want the win, I want my name on the trophy here at East Lake.
" The cool thing is that I'll be playing in the final group with Kisner and we've both just had children. My little girl was born on September 11 and his boy I think a couple of days prior to that.
" I won a week after Lex (his son) was born at the KLM Open so, although this tournament is the most important thing tomorrow, there are more important things away from the course."
Casey enjoyed a four-shot lead after a brilliant scoring burst on the front nine, the former Ryder Cup star carding birdies on the third and fifth, an eagle from 10 feet on the sixth and another birdie on the seventh after almost holing his approach.
That lead evaporated within 30 minutes as the 40-year-old failed to get up and down from greenside bunkers on the next two holes, while Kisner birdied the 13th and chipped in for another on the next.
However, a birdie on the 11th edged Casey back in front and another from 40 feet on the 17th extended his advantage ahead of what could be a hugely profitable final round.
