Lots of players on top of the leaderboard I know nothing about.  The Golf Channel was doing a piece on Cantlay's round of 71.  He could have literally put himself out of contention on a couple holes but managed only to be +1 for the day.  Also that hole where if you put it too fast it rolls off the other side LOL.  I think it was Rory who said a yard here or there off can make all the difference on a given hole.
Mavs avoid the sweep.  Between the Big 2, they only had 50 pts total, so it looks like they got some team support.
