South River, forward, junior
Down a goal late in the Class 4A state title game against four-time defending champion Bethesda-Chevy Chase, it was no surprise that Longo provided the tying goal for South River.
All season and particularly in the team's impressive playoff run, the junior forward provided the important goals.
This time, her 29th goal of the season tied the score at 1 with 7:50 to play, and the No. 4 Seahawks (18-2) went on to win in penalty kicks to claim the program's third title and first since 1997.
The three-year starter, who also had six assists this season, scored 11 goals in the playoffs, including two in the second half of the Class 4A East regional title game against rival Arundel in a 3-2 overtime win, and three more in a 4-0 state semifinal win over Bowie.
For the season, Longo had nine multi-goal games, including one four-goal performance. In her three varsity seasons, she has 55 goals and 18 assists.
"Kacie is an athletic, hard-working team player that not only set a goal to be state champions this year, but also sold her team into believing they could be state champions," South River coach John Sis said.
Also a standout lacrosse player, Longo has made a verbal commitment to play lacrosse at Maryland.
