Saturday's second and third round action of the 2018 South Florida Open presented by HandEye Supply take place at Commons Park for two rounds of 19 holes each. Florida's Calvin Heimburg opened the event with a 1054 rated, 7 under par at Snyder Park on Friday. However, the reining champion, Chris Dickerson lurks just a single stroke behind Heimburg which means we'll see them battle head to head this round.
