Firstly my apologies to the 2 ladies concerned.
A medal cannot be awarded on a countback.
Both ladies with the tied score of nett 75 will play off at the next medal round in July.
As per the Conditions of Play displayed in the locker room if one of these ladies does not play then the medal is awarded to the other. If neither plays NO medal is awarded for that round. - again my sincere apologies.
