CHATHAM,  NJ -- Three goals apiece by Kayleigh Coughlin and Sophie Straka and three goals and an assist from Ashley Kiernan provided the firepower that sent the top-seeded Chatham girls lacrosse team past county rival Mendham, 12-11, for the NJSIAA North Group 3 state championship on Thursday at Haas Field.

Chatham (19-1), winner of 14 straight, held a 12-7 lead before Mendham (13-8) made a late charge. The Cougars will play for the Group 3 state championship vs. Moorestown (16-2), 1 p.m. Saturday at Montgomery.

"Our staff is incredibly proud of our team and program today," Chatham coach Helen McCutcheon Oliver said. "We fought hard in a tough game to beat a talented Mendham team today, for the third time this season. Being our first sectional championship since 2012, and my first as a coach, it feels wonderful to see the girls’ hard work pay off.
