Scott is in outright second place and two ahead of Jordan Spieth, Patrick Cantlay and Hideki Matsuyama with Marc Leishman amongst a group in 6th place two shots further back again.
Scott added a second consecutive round of 66 to continue his move up the leader-board after his opening round of 71, a three-putt bogey at his 9th hole his only real blemish in an otherwise impressive round.
A switch to the long putter following a week of struggles on the greens in New Orleans a month ago has paid dividends for Scott having finished 8th at the PGA and now combining his great ball striking skills with an improved performance on the greens.
Scott topped off his round with an 8 iron to 3 feet at the last to complete an impressive display and set up a potential 15th PGA Tour title and a genuine tilt at a second major championship in two weeks’ time at Pebble Beach.
“Today was a really good round,” said Scott. “66 around here is good any day of the week. And I felt like I played a little better today than I have the last two days.
"A few more opportunities that I would have liked to have taken advantage of, but all in all it was really good stuff, solid. And it would be nice to put another one like that on it tomorrow and see what happens."
Scott is confident of the progress his game has made in recent times and feels good about what tomorrow might bring.
“I'm just going to play as good as I can tomorrow. I like where it's all at. I feel like the last few times I've been in with a chance, going back to the PGA Championship last year, I felt comfortable. So I'm not worried. I feel like this is the spot I'm meant to be.
“And since then, I've seen lots of good golf, and I feel like my game is at a level that, if I put it all together properly and control myself out there, I can win.”
Scott was asked what was different now than was the case twelve months ago.
“Probably just mentally. I have that sense of calm, which has always suited me on the golf course. If the brain is working overtime and stressed and busy, it doesn't look it on the outside, maybe, but internal stress levels, and that's the difference I feel. I mean, I definitely walk on the course with a calmness. Maybe it's confidence, but I say calmness, anyway.”
For Kaymer the return to contention is a welcome one having not won an event anywhere since his US Open Championship win at Pinehurst nearly five years ago.
The two-time major champion puts his improved showing in recent times down to an improvement in attitude on the golf course.
“Playing-wise, not much different, just my attitude became a little bit different over the last two or three months, more relaxed, more calm on the golf course. I was trying to force it a little bit, the success.
“And just getting away from so many things, social media, watching TV, reading stuff that is not important. What do you really gain from social media during tournament days? There's so much gossip, so much talk, so much distraction.”
Leishman kept his chances alive with a 3rd round 69 to be six shots from the lead and in the event of struggles from Kaymer then he is not without hope.
When asked where a win here tomorrow might stand amongst his career victories Leishman acknowledged the importance of winning Jack Nicklaus’ event.
“Yeah, Bay Hill, BMW, here, all big events. Lots to do tomorrow before I have to worry about that. This week I've just been trying to enjoy my golf.
“I haven't been enjoying it that much the last couple of months, just the way I've been playing and not making too many putts. It's nice to enjoy it again. That's all I'm going to be doing tomorrow.”
Aaron Baddeley improved to 15th place with his round of 68 while Matt Jones is in a share 1of 18th after a round of 69 today.
