Andrew Marty ran in a 14-yard touchdown, and an interception by Elijah Kemper on the ensuing possession sealed Wyoming's 34-27 win over Indian Hill on Friday.
The Cowboys needed a late TD and a two-point conversion to force the extra session. Wyoming had held the Indians in the first OT but failed to score.
The Cowboys improved to 4-0 and heads to Mariemont next week. It was Indian Hill's first loss of the season, and the Indians travel to Taylor.
