Chelsea Dantonio's play on Wednesday was so shocking that she even surprised herself.
The Lancaster freshman shot a 78 at Gowanda Country Club to capture her second Section VI Girls Golf Championship.
Dantonio, who won the event as a seventh grader, finished a shot ahead of last year's winner, Clarence senior Cat Peters, who finished fourth at states last year.
The top nine players advance to the state finals.
Dantonio said she didn't know she had the lead until they "added up scores" and thought she was a shot back.
"That was a good surprise," Dantonio said. "[Peters] usually beat me most of the time when we were just playing our matches so I didn't really think I'd beat her."
Dantonio was in control until a double bogey on 14 combined with a Peters par drew Peters within one. Peters then drew even with a par on 15.
Dantonio gained the lead for good when Peters bogeyed 16 after a drive to the right left her an obstructed path to the green. Dantonio made a crucial up and down for par on 17 to match Peters's par and retain the lead.
"That was probably one of the only ones I had today," Dantonio said. "My chipping wasn't really there today but my putting was."
Said Peters: "Chelsea played really well today. I had a little trouble on the greens. The ball was just flying really well and I was hitting it longer than I usually do. I ended up in the back of the greens and as you can tell they're all downhill putts when you hit to the back. I'm definitely going to go practice my putting when I get home."
