“Really solid. I probably only hit two bad shots - the tee-shot at the first and the tee-shot on the 14th,” Fox said.
“I gave myself plenty of chances again. Maybe felt like I left a couple out there but also made a few as well.
“It’s always good to go bogey-free again, it’s probably a record for me that many holes bogey-free so far this week.
“Hopefully I can continue that tomorrow.
“Obviously I’d like to get closer to (Rankings leader) Rory McIlroy and give him a bit of a run but it’s nice knowing going into Dubai that I sort of hold it in my own hands. If I can go and win that event I can probably win the Harry Vardon Trophy.
“It’s certainly a position I didn’t expect to be in at the start of the year. I’m trying to treat these last couple of events - this one and Nedbank - that I can try to get as close as possible and try to make it a bit more interesting.
“But regardless I’m pretty happy to be here and tomorrow I’ll just go out and do what I’ve done all year, just try to beat the golf course and see what happens.”
Before Fox tees up in the final round, Ko has a good chance for her second win of the LPGA Tour season after another strong round at the BMW Championship in South Korea.
Ko, who is on track to claim her second consecutive Vare Trophy for lowest scoring average on the LPGA Tour and leads the season-long Race to CME Globe, shot a six-under 66 to move into a share of second, just one shot behind rising Thai sensation Atthaya Thitikul.
Thitikul, just 19, can become world No 1 if she wins tomorrow, joining Ko as the only teenagers to accomplish that feat.
However, Ko could be in her way, after a spotless round with six birdies to continue her rise up the leaderboard.
Thitikul carded a five-under round while leader Andrea Lee could only manage a two-under 70 to slip back alongside Ko. Only five other players – including 16-year-old Minsol Kim – are within five shots of Thitikul.
Ko, who has 12 top-10 LPGA finishes this year, says she believes this is her most consistent year yet.
“I feel like this is the most consistent I’ve played in any of my seasons. Even when I was No 1, I had won more frequently in that season and didn’t have as many top 10s or the percentage of top 10s compared to how many events I was playing.
“I’m getting older so I am playing less events than my rookie year or my first few years on tour, but it’s definitely nice to be in contention a little bit more frequently, and I think that just boosts the confidence levels.
“From the middle of the season to where it is now, I don’t think I’ve ever gotten too hyped up about it or too down and that’s just allowed me to play more freely. That’s a good place for me to personally be at.
“That way, even when I’m not playing well, I don’t like let that one round affect the whole week or how I approach the next day, and it’s kind of a refresh and it’s still a learning process for me.
“I’m in a great place in my life off the golf course, as well, so it just kind of all comes together. I’m hoping to finish the season off strong but no matter what happens, I think it’s been a fun season and I’m excited for it to end but also excited for next year and what’s to come.”
On the Champions Tour, Kiwi Steven Alker could also add another victory to his successful year. He sits in second going into the final round of the Dominion Energy Charity Classic in Virginia, the opening event of the Charles Schwab Cup playoffs. Alker is two shots back from American Jerry Kelly after a second round 65 saw him move to 10-under.
