After two seasons at Michigan, Dusty May is having his first assistant coach poached. One of May's top assistants, Justin Joyner, will leave Ann Arbor at the end of the 2025-2026 college basketball season to become the new head coach at Oregon State.
The Beavers have been interested in Joyner for a while and are now expected to officially hire him soon, ESPN's Pete Thamel reported. Joyner will replace Wayne Tinkle, whom the program announced it would fire at the end of the season in February.
Joyner is currently in his second season with Michigan, having joined the team in 2024 as part of May's inaugural staff. May hired him after the 38-year-old spent the first seven seasons of his coaching career under Randy Bennett at Saint Mary's. Joyner spent his final two years with the Gaels as Bennett's associate head coach.
In his seven years with the team, Saint Mary's claimed two West Coast Conference tournament titles and made four NCAA Tournament appearances. The Gaels were WCC regular season champions in his two seasons as associate head coach.
Before coaching, Joyner played collegiately at UC Santa Barbara. He remains the Gaucho's fourth all-time leader in steals with 134.
Michigan's Justin Joyner to replace Wayne Tinkle
Once the hiring is official, Michigan's Joyner will become the 23rd head coach in Oregon State basketball history. Joyner's hiring marks the Beavers' first head coaching change since they anointed Tinkle in 2014.
Joyner takes over a program that went 17-16 in 2025-2026, just its second winning season in the last five years. Conversely, Joyner has never been part of a losing team since transitioning to coaching in 2017.
Tinkle never won more than 20 games in his 12 seasons in Corvallis. He achieved the feat twice, most recently in 2024-2025, before failing to build on that success this season. Tinkle is 37-39 in the last two years, since Oregon State joined the West Coast Conference.
