"He held on to a one-shot lead going into the last round and won by two shots, so it was touch and go," Blackledge said.
He said the weather was good for the most part and the course was in great condition.
"We had a bit of a thunderstorm on Friday afternoon but it did not stop proceedings," he said. "The course was in excellent condition even though it was a bit dry."
The prize table was valued at just under $8000 and Blackledge thanked the sponsors including Holiday Inn, 100% Golf, and New World.
