Golf in Ohio must bring out the best in William McGirt.

One month after his first PGA Tour victory at the Memorial, McGirt looked just as good two hours up the road at the Bridgestone Invitational. In his World Golf Championship debut, he opened with six birdies and finished with a 45-foot par for a 6-under 64 and a three-shot lead.

An Ohio sweep?

That’s only happened four times, and McGirt made a strong guess at the answer.

“Tiger Woods, Tiger Woods, Tiger Woods and Tiger Woods?” he said. “That would be pretty special company.”

He left out Greg Norman in 1995 (Memorial and World Series of Golf), no less a select group.

McGirt had some decent company behind him after an opening round of warm sunshine and fast conditions at Firestone. Jason Day, the world’s No. 1 player, was among three players at 67, while Jordan Spieth somehow managed to post a 68 despite having only one birdie attempt (he missed) in his first 10 holes.
