South Tama (3-4) and Mount Vernon (6-1) were tied 13 all headed into halftime.

Coming out of half, the Mustangs dominated the field three times.

STC travelled to Cornell College for the district matchup. The teams played at Ash Park Stadium, Cornell’s college field. It also happened to be Homecoming for the host team.

South Tama was dealing with a big change in their normal lineup. Kyler Smith stepped in as quarterback for the evening. Smith threw for 26 yards.

“He stepped up. We’ve given him reps so we knew what he could do. We try to make it competitive in practice. Brayden is still our guy but we were very comfortable with Kyler stepping in and he did a great job,” coach Nate Doran said.

With Smith not having many hours in varsity competition at quarterback the Trojans relied on Payton Vest to run the field.

Vest recorded 285 yards and two touchdowns. He also led in tackles with 10.5.

Matt Wiese had 24 receiving yards and one touchdown.

The two teams have competed three times in the past ten years. South Tama took one win in 2010 and Mount Vernon won the other including Friday’s contest and a game in 2011.

STC plays at home tonight for the first round of playoffs, hosting Oelwein.
