Geertsma was a standout prospect from the Northeast Procase and had carried that momentum into the 2025 NJSIAA season. The Cavaliers recruit has been nothing but impressive this season for the Highlanders. Currently ranked No. 16 in the state’s 2026 class, Geertsma carries a .475 average with seven doubles, one triple, and seven homers. The leadoff hitter leads the team in RBIs (29), runs (31), hits (28), SB (11), average (.475), slugging (.983), and tied in home runs (7). Geertsma has been a sparkplug for the Highlanders leading them to an 18-0 undefeated record so far.
