On Wednesday, the Smithtown West senior finished the job.
Clancy shot a 156 for two rounds at Middle Island Country Club to win the Suffolk County individual championship after finishing third as a sophomore and second as a junior.
Clancy, who became the second straight Smithtown West player to win the girls title, edged Ward Melville junior Danielle Greene by a single stroke.
"It's very exciting," said Clancy, a sixth-year varsity player who shot a 6-over 77 Monday and an 8-over 79 Wednesday. "It's been one of my goals for the year. I've been practicing for it and looking forward to it and really enjoyed playing. It was a great experience."
Clancy trailed Greene by three strokes after Monday's round, and the margin was unchanged after nine holes at Middle Island Dogwood Wednesday.
Clancy came back by shooting a 39 on the back nine at Middle Island Spruce. Clancy said she was just focused on each individual swing. "I just tried not to think too much about the score," she said.
"I couldn't be prouder," Smithtown West coach Tom Kane said of Clancy. "She practices tremendously hard and sets a great example. She is just a great ball-striker, the best ball-striker I've ever coached.
"Danielle Greene played really well," Kane added. "There was a lot of ebbing and flowing, particularly on the last nine holes. It was as good of a finish as I've seen."
Smithtown East won the team title and was led by sophomores Peyton Greco and Alexa Niven, who finished third and fourth individually. Smithtown East will play in the Long Island Championship next Thursday against Syosset at Middle Island.
