Visiting Sussex Hamilton, seeded seventh in the sectional, upset No. 3 seeded Arrowhead Saturday night in a WIAA Division 1 boys basketball regional championship game at Arrowhead, 65-63.
Jake Knueppel made a layup with two-tenths of a second remaining in the game to give the Chargers the wild, come-from-behind victory.
Hamilton trailed 63-60 with less than 10 seconds to go when red-hot sophomore Brady Ellingson made a 25-foot, 3-pointer with 7.4 seconds left. AHS then turned the ball over with 3.0 seconds to play and Hamilton then won the game when they perfectly executed a three-pass inbounds play that resulted in Knueppel scoring at the buzzer.
Ellingson fired in 33 points for the Chargers, scoring 22 of those in the second half. Nick Patterson had 9 points for the winners.
AHS senior Ryan Saeger led the Warhawks with 24 points. Sophomore center Billy Hirschfeld added 15 points and 11 rebounds for AHS.
