Scheffler +3, Morikawa Par, Hovland +1 (F)
Scheffler two-putts from 30 feet on the par-4 18th to card a lacklustre 3-over 73.
The World No.1 is seven shots off the pace heading into the second round.
The bookies have pushed his odds out from 11/4 starting the tournament to a current 6/1.
He's incredibly still the favourite, now alongside Rahm.
Scheffler will be off early on Friday, however, and no doubt intent on hauling himself back into contention heading into the weekend.
Morikawa and Hovland both made birdies on the par-4 18th playing alongside Scheffler.
Hovland sent home a tramliner to card a 1-over 71, while Morikawa drained a six-footer to card a level-par 70.
That's it for our R1 updates today.
