After three weeks of elite fields and familiar golf courses, there's a significant gear shift as the PGA Tour returns to Detroit for the Rocket Mortgage Classic. Where Colonial, the Heritage and the Travelers Championship all attracted every member of the world's top five, even if Brooks Koepka sensibly chose not to take up his engagement last week, this event has none of them. In fact, just five of the top 20 are set to tee off - all being well - in a tournament which represents a drop in grade.

He'd never admit it, but that should be music to the ears of Bryson DeChambeau, who has threatened in all three tournaments since the resumption and is now as short as 11/2 having been backed already. I absolutely get it. DeChambeau might well be on the cusp of the best golf of his life, and his strike-rate as a professional is very respectable already. It may be that we look back upon these weeks and months as the transition from good to great, and whether that is true or not he can steamroll any field should everything click.

The trouble is, he's now a single-figure price, on a golf course he does not know, and there remain areas of his game which need addressing. One is his chipping, long a source of great debate in the commentary box. The other is his distance control: had Lennie from Of Mice And Men been a golfer, I reckon he'd have suffered the same issues as DeChambeau did last week. He'll work it all out, but for now costly mistakes are almost guaranteed and taking short prices doesn't appeal.

With Webb Simpson arriving here after a stressful, draining fortnight, the likes of Patrick Reed, Tyrrell Hatton, Viktor Hovland and Hideki Matsuyama make more sense and this may not take all that much winning. Should any of this quartet produce the best bits of their golf from the last few months, chances are they'll land the place money at least as they contend down the stretch on Sunday.

Perhaps Hatton is still being underestimated now that he's playing the golf of his life, but backing him at 16/1 doesn't come easily and it's probably best to be somewhat cautious here. Not that we should rush to conclusions following the inaugural edition of this event last summer, but a runaway victory for 250/1 shot Nate Lashley, the last man into the field, tells us something. We are very likely in for another shootout, and that likely widens the lens when it comes to potential winners.
