(CNN) The only person who can beat Brooks Koepka heading into the final round of the US PGA is likely to be himself.
Brooks Koepka seven clear heading into final round of US PGA
The all-powerful Koepka leads by seven shots after two record-breaking rounds and a solid third to leave the field trailing in his rearview mirror at Bethpage, New York.
The defending champion shot a level-par 70 on a breezy, sunny Saturday on Long Island to reach 12 under as he tightens his grip on a fourth title in his last eight majors.
The muscular Floridian will play Sunday alongside countryman Harold Varner III, who heads a chasing quartet at five under alongside another American Luke List, Thailand's Jazz Janewattanond and Koepka's close friend Dustin Johnson, the world No.1.
The 29-year-old Koepka has been impregnable this week, blending his brute force with a killer short game, deft putting touch and seemingly unflappable, single-minded demeanour.
His opening 63 was a course record and his 65 Friday gave him the lowest 36-hole score in major history. His seven-shot lead heading into the final round is also a US PGA record.
Koepka is aware of the records stacking up, but insists his focus is on just winning a second-straight US PGA to go with back-to-back US Opens.
"I couldn't care less about breaking any records," he told Sky Sports. "I'm just trying to win a golf tournament."
If Koepka's demeanour is deadpan, his golf has been anything but as his explosive brand of the game has overpowered Bethpage's infamous Black course this week.
Comparisons have naturally been drawn with Tiger Woods in his pomp, after beating the Masters champion by 17 shots over two days and forcing the 15-time major winner to admit he's playing a game few can live with, as Woods did in his heyday.
