Rivas, a senior forward from Greenfield, tallied a pair of important goals during Sunday's men's soccer match at Wittenberg to help the Cardinals notch an important result.
Rivas tied the match at 1-1 on a goal in the 11th minute, and notched an equalizer later on at the 77:39 mark, on a header off a corner kick, that eventually helped force overtime.
Otterbein will have a pair of home matches this week, hosting No. 5-ranked Ohio Wesleyan on Wednesday before battling Ohio Christian come Saturday afternoon.
