NORMAN, Okla. (AP) Mark Cody resigned as Oklahoma's head wrestling coach Thursday, saying he believed it was time for new leadership.
Cody led the Sooners to a 55-34 record over five seasons that included a 10th-place NCAA Tournament finish in 2014.
''I am extremely grateful to have had the privilege to coach at the University of Oklahoma,'' Cody said.
Cody came to Oklahoma after nine years as head coach at American University. He led the Eagles to a program-best fifth-place finish at the 2011 NCAA championship. Cody was also an assistant coach at Oklahoma State, Nebraska, Missouri and Bloomsburg.
Athletic director Joe Castiglione said Michael Lightner, who has served as an assistant coach for the last seven years, has been named interim head coach. Lightner was a four-time Big 12 champion and four-time All-American at Oklahoma, and won a national title in 2001.
''I want to express our sincere appreciation for the leadership Mark has provided the last five years,'' Castiglione said. ''In addition to producing some highly accomplished wrestlers, he developed high-character student-athletes who also performed well in the classroom.''
Cody coached five Sooners' wrestlers to a total of 10 All-America honors. Two of those All-Americans, Kendric Maple in 2013 and Cody Brewer in 2015, won national championships.
