Bryson DeChambeau was listed as a slight favorite to start the week of the AT&T Byron Nelson, according to PointsBet Sportsbook. He was originally at +850, while world No. 1 Dustin Johnson and world No. 3 Jon Rahm were at +900.
And then Johnson withdrew on Monday and when the dust settled, Rahm had joined DeChambeau at the top. The two are now listed at +800, with Jordan Spieth a clear third at +1000.
DeChambeau is coming off a solid weekend at the Wells Fargo, which saw him tie for ninth after mistakenly flying home to Dallas thinking he had missed the cut.
