Justin Thomas enjoyed "one of those freaky days in the zone" as he carded a course-record 11-under-par 61 to vault to a six-stroke lead in the third round at the BMW Championship at Medinah on Saturday.
An eagle with an eight-iron from 180 yards at the par-four 16th was just one highlight of an eventful day for the American, who broke by two strokes the previous best score at Medinah, set just 24 hours previously by Hideki Matsuyama.
Halfway leader Matsuyama could not replicate that performance on Saturday, plunging 10 strokes behind with a 73.
Thomas posted a 21-under 195 total in the penultimate event of the PGA Tour season, while compatriots Tony Finau and Patrick Cantlay fired 68s for a share of second place on 15-under.
“I hit the ball pretty unbelievable,” Thomas told broadcaster NBC. “It’s not like I made any long putts. I hit it close to the hole, and took advantage of some opportunities.
“I got a couple of good breaks and that’s stuff that happens when you shoot 11 under.”
Thomas started his round with five successive birdies, and later recorded a tap-in eagle at the par-five 10th.
The highlight reel continued when he chipped in from 20 feet from lush rough to birdie the 14th hole.
He then drove his tee shot into a pond at the 15th and took a penalty stroke, but still saved par, setting the stage for his most unlikely eagle at the par-four 16th, where his ball landed a couple of yards in front of the cup and trickled in.
“It looked good in the air,” he said. “That’s a little bit of a bonus.”
Thomas finished with two eagles, eight birdies and one bogey, and vowed to continue attacking the rain-softened course in the final round.
“I’m trying to win by as many as I possibly can. If I just keep playing how I’ve been playing I feel like I can shoot another good round.”
The performance was a reminder of the talent possessed by Thomas, who clinched his first Major title two years ago at the PGA Championship and has been ranked number one in the world.
But his 2019 campaign suffered a setback when he injured a wrist in March and he eventually took six weeks off to let it heal, missing the PGA Championship before missing the cut at the US Open.
Rory McIlroy dropped two places to a share of 13th position after a two-under 70. British Open champion Shane Lowry had his best round of the week at the no-cut event, a four-under 68 that included an eagle-three on the par-five fifth moving him to two under. Graeme McDowell is also on two under after a one-over 73.
