On the soccer pitch this fall, Marietta High juniors’ Allison Fouss and Maegan Grosel have been the equivalent of a double-barreled shotgun blast. Anytime they shoot, the ball has the potential of going into the back of the net for a score. Going into tonight’s scheduled 7 p.m. Ohio Division I regional semifinal against Upper Arlington High at Logan High, Fouss owns a Lady Tiger-high 23 goals, while Grosel has 21. The two girls had shared the team high in this offensive category until Fouss scored two goals to spark MHS (16-1-3) to a 2-1 come-from-behind triumph over Tri-Valley (11-4-4) in a district final at Logan Saturday. With those two scores, Fouss set the single-season, school record, breaking the mark of 22 held jointly by Whitney Price and Casey Price, the daughters of Marietta girls head coach Jeff Price. Coach Price, of course, is counting on Fouss and Grosel to be double trouble at the top for Upper Arlington, which is No. 5 in the state with a 16-1-2 record.
