Leaders are Day and Cauley at -5. Looks like anything at 3-under or better is a pretty good score for the day.
Early results:
John Rahm - not teed off yet
Brooks Koepka - 4 under thru 17
Colin Morikawa - 1 under thru 17
Tyrrell Hatton - 1 over thru 17
Daniel Berger - 3 under thru 18
Abraham Ancer - 3 under thru 14
I've got 3 guys really in the running with my big gun yet to tee off. Feeling good so far!
