The Lady Braves won their 11th straight match Wednesday with a 25-15, 25-11, 25-19 victory over Avila University in Wilson Field House.
The 23 victories are the most since the 1991 season when Ottawa went 26-17 under coach Patti Masten.
The Lady Braves were led in kills by Allie Arnold. The sophomore middle blocker had 12 kills on 24 attempts with two errors for a .417 hitting percentage.
Chrissie Jeannin led Ottawa with 36 assists and Kristen Hendrickson had 10 digs. Arnold also led Ottawa with four blocks.
Ottawa (23-5, 14-0) plays 6 p.m. Saturday at home on senior night. A win would give Ottawa at least a tie for the conference championship.
Seniors Janelle Jenkins, Hendrickson, Jeannin, Katie Jensen, Megan Gillespie and Shelbie Glissman will be honored.
