The pair has a one shot lead over Kevin Chappell, Brendon Todd and the ever present Jim Furyk as the field heads into the weekend.
Scott, the world number two and the winner of eleven PGA Tour titles, is up against a man who has yet to win on the PGA Tour in Tringale but with essentially every one of the game's leading players in pursuit of the riches of the Playoffs their task is far from done.
Scott began slowly today but four birdies in succession before the turn moved him into contention and he finished it off with a couple more over the closing nine holes to take a share of the lead.
Scott is currently projected to take the lead in the FedEx Cup points race although there are countless permutations which might see that change over the final 36 holes.
"I think I learned a lot out of the major season this year," said Scott after the round when asked if his year had been a disappointment in terms of not winning a major. "I mean, going to defend the Masters was a new experience for me obviously, and I played well for the week bar Saturday. That's an important day; they are all important.
"I think we saw guys win on top of their game not looking back, just going forward. Martin blew the field away and Rory pretty much blew the field away after the finish on Saturday at The Open to open up six is a big lead, especially when you're playing like he was.
"I think the mind set had to change a little bit, and I tried to do that at the PGA but I didn't play very well. I played some of my worst golf of the year. So the mind set was that you're going to have to attack a little more and not just plod your way around and avoid the big numbers.
Tringale, who was disqualified from the recent PGA Championship, has generally had a good season in fact just to get to this point you need to have had at least a reasonable one and any player capable of qualifying to play this event is more than capable of leading at some stage. Whether he can continue on remains to be seen.
Of the other Australians Jason Day is well poised at 6 under and just two from the lead after a second round of 64.
John Senden is five from the lead in in 27th position along with Stuart Appleby, Steven Bowditch is 39th.
Matt Jones, Aaron Baddeley, Robert Allenby, Marc Leishman and Geoff Ogilvy missed the cut with Baddeley now unlikely to make the top 100 for next week's Deutsche Bank Open and Allenby's 2014 PGA Tour season over.
Even Appleby must play well over the weekend to remain in the FedEx Cup playoffs.
