Just as Tiger Woods took a while to recover from putting everything into winning the Masters, Brooks Koepka hit a wall Saturday after his PGA win and subsequent U.S. Open push to win a third in a row.

It’s one thing when 43-year-old Tiger is on fumes, but to hear Koepka say he’s “fried” suggests it might be tougher, not easier, to win a Grand Slam with the new schedule.

From Nick Menta’s GolfChannel.com story:

“I'm just pretty – I don't think I'm even over the PGA,” he said. “And then to exert all your energy there last week, just fried. I mean, I've caught myself yawning on the golf course. I don't think I've ever yawned on a golf course before.”

In fairness, Koepka has yawned before – in a way that was weirdly perfect – but it’s clear that last week’s run at a third consecutive U.S. Open title took a lot of him.

Asked why he made the cross-country trip here after Pebble, Koepka said he wanted to honor his commitment and that he couldn’t have known in advance he would be this drained. Considering the reason, he’s happy to feel fatigued.

“When you're planning your schedule, you're not thinking you're going to compete in all three majors and still be fried from it,” he said. “It's fine. I don't mind it.”

It’ll be interesting to see what the combination of The Open followed by a WGC, a week off and then the playoffs yields in the way of energetic play from the game’s stars. In the hottest month of the year.
