The Cheyenne East Thunderbirds ran their season record to 7-1 and Cheyenne South notched their first victory of the season in local class 4A football action on Friday night.

The T-Bird defense picked off Tiger quarterback Graedyn Buell three times and held running back Mason Randall to 38 yards en route to a 31-6 thrashing of Rock Springs. Randall came into the game as the leading rusher in Class 4A, averaging over 150 yards per game.

The win means East could clinch the top seed in the Class 4A playoffs, but it won't be easy. The T-Birds would have to defeat unbeaten Sheridan (8-0) on the road and hope Rock Springs (4-4) can upset Casper Natrona (7-1) in Rock Springs on Friday.

If East and Natrona both win, there would be a three-way tie for first place to end the season. That would probably mean the post-season seeds would be determined by a coin flip.

Meanwhile, Cheyenne South (1-7) notched its first win of the season over Campbell County (0-8) on Friday night, 53-27. The road win for the Bison marked their first-ever win over the Camels, and also set a South scoring record for football. The Bison will close out the regular season with an intra-city battle at home against Cheyenne Central (1-7).

That battle will for all intents and purposes be a play-in game for Class 4A playoffs, because the winner will grab the number 8 seed. Kickoff for that game will be at  6 p.m. Friday at South.

The Indians fell at home to Casper-Natrona 63-20 on Friday. One bright spot for Central was the play of Sophomore quarterback Dawson Macleary, who completed 14 of 22 passes for 236 yards and two touchdowns.

But it wasn't enough to overcome almost 500 yards of total offense by the Mustangs, who jumped out to a 29-0 lead in the second quarter.
