The third set was the most important for Manhasset.

Behind three-set wins from first singles Amanda Foo, first doubles Kyleigh Harmon and Lia Frankis and second doubles Alina Zhitnik and Yaya Wang, the Indians defeated Cold Spring Harbor, 5-2, to capture its second straight Nassau girls tennis championship Friday at Eisenhower Park.

"This is amazing," Foo said. "It was incredible to win last year and to repeat is fantastic. It was harder for us this year -- we had never played Cold Spring Harbor during the season -- and we weren't sure what to expect."

It ended just like every other match has this season for Manhasset (17-0).

"When we got into these thirds sets, we've had a lot of those matches where we've jumped out in front with the first set and then hit a lull," coach Eileen Cuneo said. "That's something we've worked on during the entire season. It's all about determination, perseverance and commitment."

Foo dropped a tightly contested first set, 7-5, to Seahawks eighth-grader Merri Kelly Hannity. Foo fought back to win the second set, 6-4, and defeated Hannity, a 2015 individual county finalist, 6-4, in the final set.

"When I dropped the first set I was just trying to tell myself, 'come on Amanda, you can come back, relax,' " Foo said. "I was able to come back mentally stronger and I did it."

Hannity survived four match points with Foo leading 5-3 before earning the break to get back on serve. Foo stayed focused and was able to break Hannity to win the next game and the match.

"I always tell them not to think about the last point, only think about the point you're in," Cuneo said. "Amanda gets that type of reinforcement from the people that she works with outside the team but in the end it's about her. I'm so proud of the entire team's determination."

Harmon and Frankis defeated Jillian Butta and Hailey Albers, 6-2, 2-6, 6-4 and Zhitnik and Wang beat Dylan Beder and Katherine Faria, 7-5, 5-7, 6-4.

Manhasset's other wins came at second singles, where Stephanie Petras defeated Maddy Richmonod, 6-0, 6-3, and at third singles, where Brooke DiGia beat Daniella Morris, 6-0, 6-1.

A new format allowed teams from every conference to challenge for playoff spots instead of just Conference I teams, as in the past. Cold Spring Harbor, the II-A winner, finished the season 16-2.
