Tommy Fleetwood was so locked in on good golf he didn't realize until after his 7-under 63 that he didn't miss a fairway in the Travelers Championship. And he certainly wasn't aware of the stunning blowups behind him by Scottie Scheffler and Justin Thomas.
All three started a steamy, hot Saturday tied for the lead, but not for long.
Scheffler celebrated his 29th birthday by starting a round with a triple bogey for the first time in his PGA Tour career. All it took was missing the fairway into thick rough, airmailing the green from a front bunker, two chips and two putts.
He never quite recovered, posted a 72 for only his fifth score over par in 55 rounds this year, and was nine shots behind.
Thomas was still in the mix until a wild hook off the tee at the par-5 13th, letting the driver loose that landed near the marshal spotting the shot. After reloaded from going out-of-bounds, it took three chips left of the green and two putts for a quadruple-9. He shot 73 and was 10 shots out of the lead.
