FULLERTON, Calif. – Cal State Fullerton head baseball coach Jason Dietrich has decided to step down, citing family reasons. His resignation will be effective immediately.

"This has been an incredibly difficult decision, but ultimately, I believe it is the right decision for both my family and the Titans baseball program," Dietrich said. "A year ago, my wife and kids made the decision to move back to North Carolina, with my son beginning high school. Being away from them over the past year has been challenging, and after a lot of thought and consideration, I feel now is the right time for me to return home and be with my family."

Dietrich said the nine years he has spent at Cal State Fullerton, including the past five as head coach, "have meant the world to me." 

"I want to thank all of our fans, alumni and donors for their unwavering support of Titans baseball," Dietrich said. "I will always be proud to be a part of this program and will continue to support the Titans and cheer them on in the years ahead."

When Dietrich started at Cal State Fullerton before the 2022 season, he became the sixth head coach in the program's history. In his second season at the helm, Dietrich led the Titans to an NCAA Regionals appearance. 

"I'm grateful for Coach Dietrich's dedication and contributions to our baseball program, particularly the current culture he helped establish," said CSUF Vice President for Intercollegiate Athletics Jim Donovan. "I completely understand and respect his decision to be closer to his family, and I'm grateful for his commitment to our student-athletes and the Titans. I wish Jason and his family nothing but the best in the future."

Donovan announced that Cory Vanderhook will be named interim head coach through the 2027 season. Vanderhook returned to Cal State Fullerton as an assistant coach on Aug. 14 after spending the past seven seasons at UNLV.
