The defending Korea Blue regular-season and tournament champion Cougars can seal second place and the No. 2 seed with a win by four or more goals in their regular-season finale. The host Blackhawks have two matches left, including Saturday’s season finale at Yongsan, which also has 22 points but has lost twice to Osan and tied Humphreys 1-1. Humphreys wins over the Cougars and Guardians would give the Blackhawks 25 points, second place and the No. 2 KAIAC seed.Players to watch — Where the Blackhawks are concerned, it’s all about goalkeeper Elayna Snyder (16.4 saves per match) and freshmen midfielders Arielle Stickar (six goals, four assists) and Hayden McMillan (school-record 15 goals, four assists). The Cougars have historically been defense-minded, but still get solid production from junior Lizzy White (11 goals) and senior Jana Rafi (six goals) and strong playmaking from junior midfielder Maja Inthavixay (eight assists).
