PGA Championship: What caused Bryson DeChambeau's 'inexplicable' start and LIV Golf star's latest struggle in majors?

Bryson DeChambeau's torrid start to the major season continued at the PGA Championship, extending a run that has seen him experience a noticeable slump in the sport’s biggest events.

DeChambeau is a two-time US Open champion and has finished runner-up at the PGA Championship in each of the last two years, although has seen his major form disappear since ending tied-second to Scottie Scheffler last May.

His title defence at the US Open a month later resulted in a missed cut, having finished no worse than sixth in five of his previous six major starts, with his share of 10th at The Open coming after he started with an opening-round 78.

DeChambeau was among the favourites to challenge Rory McIlroy and Scheffler at The Masters, having arrived with back-to-back victories on the LIV Golf League, only to suffer an early exit after rounds of 76 and 74.

The world No 28's nightmare opening rounds in majors continued Thursday at Aronimink Golf Club, with a six-over 76 the fourth successive major where he started with a round of three over or worse.

DeChambeau declined to speak to the media post-round, just as he did each day during last week's LIV Golf event in Viriginia, with former Ryder Cup captain Paul McGinley questioning whether uncertainty over the circuit's long-term future is a possible reason for the drop-off.
