Awards and honors
2015 was another award-winning year for Oregon State. It was the fourth straight year a Beaver player garnered a major conference award and third year in a row that at least four players were named to the All-Conference First Team.

Postseason

Oregon State was the #2 seed of the Dallas Regional with host and #1 seed Dallas Baptist, #3 Texas and #4 Virginia Commonwealth. After winning their first game against Texas the Beavers were eliminated after dropping two straight versus VCU and Dallas Baptist.
