Two battles will be fought Monday during the rain-delayed final of the BMW Championship.
Popular veteran Jim Furyk will try to turn his Friday 59 into a win, starting with a one-shot lead over Steve Stricker.
And players on the FedEx Cup points bubble will try to earn their way into next week's 30-man Tour Championship.
Furyk had shot 69 Saturday to get to 13 under, good for a one-shot lead over Steve Stricker with second-round co-leader Brandt Snedeker another shot back and Zach Johnson alone in fourth three shots back.
Tiger Woods starts the day alone in fifth at 9 under.
