Athletic Director Jay Jacobs made the announcement after the Tigers finished the 2013 season winning just seven of 24 SEC games. Auburn's overall record was 30-23 this year.
During her tenure the Tigers posted a record of 212-272 in SEC games. Overall her record at Auburn since making the move to AU from Huntingdon College in Montgomery was 562-458-1.
"I deeply appreciate Tina's many contributions to our program," Jacobs said in a statement as part of the announcement of a coaching change. "She started it from the ground up, and I will always appreciate her role in establishing a foundation for Auburn softball. I made this decision because I felt it was time to move in another direction."
The Tigers missed the SEC Tournament, which is taking place this week in Lexington, Ky. Ten of the SEC's 13 teams qualified for the league tournament.
"I'm very fortunate to have had the opportunity to coach the Auburn softball program the last 17 seasons," Deese said. "I'm disappointed that I will not be there to lead the team moving forward, but would like to thank the players, coaches and support staff that have been part of the program since I arrived in 1995. I'm also very appreciative of the Auburn family, community and university during my tenure, and wish the program nothing but the best."
Auburn's RPI of 66 puts the Tigers well behind three other Division I programs in the state this season. Alabama and South Alabama are both rated in the Top 20 in RPI while UAB is 38th.
