The Avonworth football squad had a case of slippery fingers yesterday, and South Side Beaver made them pay for the miscues.

Host South Side Beaver (4-3, 1-3) capitalized on four lost Avonworth fumbles to earn a narrow 21-20 victory in the WPIAL Class A Big Seven Conference. Avonworth (2-5, 1-4) was lucky to lose the football just four times, as the Antelopes fumbled seven times.

South Side Beaver won despite losing the total yardage battle, 263-180, including a 241-105 Avonworth advantage on the ground.

Jonathan Bushmire had a receiving touchdown for the Rams and Jordan Potts and Eric White rushed for scores. White's decisive 4-yard touchdown run came with 8:36 remaining.

Avonworth's potential winning drive ended when it turned the ball over on downs with 2:40 remaining.
