LOUISVILLE, Ky. (AP) — Right when it felt like there was no stopping Scottie Scheffler on any of golf’s biggest stages, along came a few viable candidates, just in time for the PGA Championship.

Rory McIlroy has won his last two starts, hitting top form as he returns to Valhalla Golf Club, the site of his 2014 PGA title, which also happens to be the last major he won.

Defending champion Brooks Koepka bounced back from a 45th-place finish at the Masters, which Scheffler won in a runway, for a victory on the LIV Tour.

Scheffler, meanwhile, already has four wins this year: at The Players, the Masters, Harbor Town and the Arnold Palmer Invitational. What could possibly slow him down? Well, his wife, Meredith, gave birth to a baby boy, Bennett, on May 8.

“I was sitting there with a newborn in my arms and the green jacket in the closet,” Scheffler said of the off time he spent after Bennett was born. “It was a pretty special time, I think, at home. But at the same time, I think the competitiveness in me doesn’t let me reflect too much and I was trying to do my best to get ready to play this week.”
