From defensive to apologetic, at least Bryson DeChambeau now understands that he was part of the problem.

The overtly analytical golfer was ridiculed this past week at The Northern Trust at Liberty National in Jersey City for his consistently slow play. It drew the ire of many players, some voicing their opinions online and some in person. That would include a face-to-face encounter on the Sunday morning putting green with one of slow-play’s biggest opponents, the hulking Brooks Koepka.

It also was an impetus for the PGA Tour to issue a statement saying they would review their policies on the issues.

Now as the FedEx Cup playoffs move to the second leg this week in Chicago, DeChambeau took to Instagram to admit that he is in the wrong and hopes to improve on his snail-like pace. He also acknowledged the clear discomfort from his Saturday playing partners, Justin Thomas and Tommy Fleetwood.

“Slow play affects the quality of the game for both players and our fans and I’ve always had the utmost respect for my playing partners, including JT and Tommy,” DeChambeau wrote. “I’m constantly trying to improve and I will do my very best to improve my pace. Golf is my passion and livelihood. It’s my responsibility to help improve the game to be more enjoyable for all.

“Pace of play has been an issue for golf at all levels for a long time, and I’m committed to being a part of the solution, not the problem. I want to be a good representative of the game and the @PGATour and I looking forward to working with the TOUR and fellow players to find a solution to slow play.”

DeChambeau, who goes into this week ranked No. 20 in the FedEx Cup standings, first rebuked the idea that he was slow, citing the pace at which other golfers and their caddies walk. But video of him in Jersey pacing off a 70-yard shot and taking over three minutes to hit, along with another time when he took over two minutes to hit a 10-foot putt, both show that he often goes over the allotted 40 seconds to hit a shot.

One response to the video on Twitter came from plucky Englishman Eddie Pepperell, who had called DeChambeau a “single minded twit.” Pepperell then apologized, and said he was off to Prague to play in the Czech Masters and get his mind off this inane controversy.

“Keep your eyes peeled as there’s a chance I might be on TV, and you’re gonna wanna see my new routine,” Pepperell wrote, adding a emoji of a man running.
