The not so good news is that there are 11 teams with 15 shots of the lead with 54 holes of golf left to play.
That means the tournament is a long way from over.

#1 South Mountain is two shots back in third.
Darton's Lion An and Jin Chung are fifth overall after both shot 71.
Andy Lewis had a 72 for Darton and Evan Hanna's 76 was the fourth score reported.
Aaron Elrod shot a 77.
