Rory McIlroy described the unusually fast fairways at Royal Birkdale, host of this week’s British Open, as a “double-edged sword” following a recent heatwave in northwest England that has significantly hardened the course. The dry and sunny conditions have accelerated the roll of golf balls, affecting both shot strategy and course difficulty.

McIlroy, the 37-year-old Northern Irish golfer and reigning US Masters champion, noted that while the firmer, faster fairways might benefit players who typically struggle with driving distance—allowing their shots to gain extra roll—there is also a reduced penalty for errant tee shots. "When I was here a couple of weeks ago, the rough was much more penal than it’s going to be this week. It’s definitely burnt out a lot," he said.

The past few weeks of elevated temperatures have rendered the rough less punishing, which McIlroy indicated could change how players approach their tee shots. He emphasized the importance of avoiding the fairway bunkers, suggesting that some competitors might opt for a more aggressive driving strategy to bypass these hazards. “It might be in the rough, but it’s not that penal, so you get a wedge in your hand and you can figure it out from there,” McIlroy explained.

This British Open marks McIlroy’s pursuit of a second title in the tournament, having first won it in 2014 at nearby Hoylake. His insights carry weight given his status as one of only six golfers to complete the career Grand Slam, securing victories in the British Open, US Open, US Masters, and US PGA.

Defending champion Scottie Scheffler also weighed in on the course conditions, highlighting the challenges posed by the firmness and speed of the fairways. The American, who missed the cut last week at the Scottish Open—a rare lapse in his four-year run of making major event cuts—characterized the ball as “just going to run forever pretty much” at Birkdale. Scheffler discussed the strategic decisions players face off the tee, weighing whether to opt for driver and risk playing from the rough or to use irons to find the fairway and set up longer approach shots.

“The firmness creates a whole lot more challenges just to try to control your ball and figure out where it’s going to end up,” Scheffler said, emphasizing how the altered conditions have introduced an added layer of complexity to the tournament’s traditional links-style test.
