Brooks Koepka holds one-shot lead going into final round of US PGA Championship 2023 at Oak Hill

Brooks Koepka hit a second straight 66 at Oak Hill to lead the US PGA Championship going into the final day.

The 33-year-old is a two-time US PGA Championship winner and has won four majors in total.

A second-straight 66 gives Koepka, a winner here in 2018 and 2019, a one-shot lead going into the final round.

Despite the heavy rain and rather challenging conditions, Koepka kept his head and delivered a resilient performance that propelled him to six under overall. Corey Conners and Viktor Hovland sit in striking distance at five under, followed by Bryson DeChambeau two shots back.

Justin Rose and Scottie Scheffler trail Koepka by four, with Rory McIlroy five strokes behind.

DeChambeau, who was also booed, spoke after the day’s play on the crowd reaction.

He said: “I don’t care. I mean, it’s not a big deal. They are going to do that no matter what. You know what, look, it’s New York, and I expect it here. I appreciate the fans. Them doing that to me it’s like, okay, cool, no problem. If we got applause, that’s fantastic and if not, you know what, whatever it is, it is.”

He said: “I know what I did at the Masters, but it won’t happen this time. It’s kind of irritating but I’ll never do it again.”

Koepka’s current form, fitness, and mental resilience make him a formidable competitor.

Back-to-back birdies on the fourth and fifth, and 12th and 13th holes contributed to his strong round, although a bogey on the seventh hole showed he wasn’t having it all his own way.

Meanwhile, Conners and Hovland, both vying for their first major victory, made late errors that will likely prove costly. Conners picked up a double-bogey on the 16th after landing in a sand trap, while Hovland’s uncontrolled drive on the 18th led to a bogey of his own.

Barely mentioned in dispatches after a two-over 72 in his first round on Thursday, Koepka has stormed into the lead on the back of two sterling performances.

2021 champion Phil Mickelson made history by making his 27th cut at this event, equalling the record of Jack Nicklaus and Ray Floyd.
