The RPI is a mathematical system the NCAA created to rank teams based on win-loss record and overall strength of schedule. In addition, the RPI in recent years has been one of the most heavily weighted criteria pieces that the women's volleyball selection committee uses when creating the 64-team NCAA Tournament.
The Mastodons (15-3, 5-1 Summit League) are tied for first-place in the Summit League and are one of 13 teams in the nation with at least 15 victories this season. IPFW in non-conference play also had signature victories against Georgia and Ball State, while losing on the road in five games against No. 25 Michigan State.
In this latest RPI, the Mastodons are the fifth lowest ranked team with three or fewer losses.
IPFW is the only Summit League team ranked in the top 100 of the RPI. South Dakota State, which IPFW swept on Friday, is the second-highest ranked Summit League team at No. 123.
IPFW had the third-best RPI ranking of any team from Indiana. Purdue led all teams in the state with a No. 10 RPI ranking and Notre Dame was ranked No. 50.
The No. 55 ranking is one of the highest RPI rankings for IPFW in recent years. The Mastodons finished last season at No. 77 in the RPI and did not receive an at-large bid to the NCAA Tournament after losing in its conference tournament.
IPFW will continue conference play and attempt to extend its six-match winning streak as it travels to play Nebraska-Omaha at 8 p.m. Friday.
