In the best-of-three playoff series with Oregon, the road teams won the first two games, which were played six nights apart. In the deciding third game in Eugene the next night, the home team rallied from a six-point deficit at halftime to win by a basket; Oregon advanced to the eight-team NCAA tournament, but lost their opener by three points.
