Looking for a remarkable fourth win in his last six events, Scheffler shot a stunning second-round 67 to post a midpoint total of eight under par at August National.
It gave the 25-year-old American a five-stroke lead over the defending champion Hideki Matsuyamawinner 2011 Charles Schwartzelireland Shane Lowry and first-round leader Sungjae Im.
Four of the previous five players to hold such a halfway lead went on to win the green jacket, with Jordan Spieth the most recent to do so in 2015.
“I feel like my game is in a good place,” Scheffler said with considerable understatement.
“Once I saw that I had taken the lead, my first thought was to keep trying to build it just because I feel like I’m playing well.
“That will be the focus on Saturday, just to keep getting myself in good positions, executing shots and as long as I’m committed to everything, everything should be fine. The rest is really not up to me.
