2018 Mid-Amateur Player of the Year
Dull, the 2017 Amateur Player of the Year and Mid-Amateur Stroke Play Champion, picked up 2018 right where he left off. Outside of FSGA play, he won the prestigious Gasparilla Invitational at Palma Ceia, holding off a strong national field. In March, he finished tied for third alongside partner Jeffrey Horn at the Senior/Mid-Amateur Four-Ball Championship. Dull was victorious in May at the Mid-Amateur Championship at Coral Creek Club.
In June, Dull jumped out to an early lead at the 101st Amateur Championship, and battled to hold it through the entirety of the tournament. Lench would make a crucial birdie on the 18th to force a play-off with Dull and eventually defeat Marc on the 2nd play-off hole. In USGA Championships, Dull saw success again, advancing to the final match of the US Four-Ball Championship with partner and 2016 Mid-Amateur Champion, Chip Brooke. He also advanced to match play at the US Mid-Amateur Championship.
Most recently, Dull was the Captain of the victorious North Team at the Florida Cup matches and went 3-0.
2017 Amateur Player of the Year
After a spectacular run at the 2015 US Mid-Amateur Championship, Marc Dull has become a household name in amateur golf events around Florida. In 2017, Dull continued his reputation of knocking on the door at FSGA Championships, before finally breaking through and earning his first FSGA victory at the Mid-Amateur Stroke Play Championship in October, and locking up Player of the Year honors while doing so.
In August, at Southern Hills Plantation Club, Marc would advance to the Semifinals, falling to eventual Champion, Jacob Huizinga, 1up. In October, Marc once again participated in the US Mid-Amateur Championship, and narrowly missed out on advancing to match play. Later that week, Dull would arrive at the FSGA Mid-Amateur Stroke Play Championship at The Country Club of Winter Haven, and open with a five-under-par 67, and never look back earning his first FSGA Championship in a wire-to-wire victory. The victory also gave Dull enough points to lock up FSGA Player of the Year Honors. One week later, Marc represented team Florida in the Southeastern Challenge Matches, posting a 3-2 record.
