Cal State Fullerton has placed its head baseball coach on leave, the university announced Thursday.

"Effective today, Cal State Fullerton's head coach Rick Vanderhook has been placed on paid administrative leave. The university has received allegations that it is obligated to review," a school release said.

"Assistant coaches Mike Kirby and Jason Dietrich will serve as acting co-head coaches when the Titans take on Cal Poly San Luis Obispo on Thursday afternoon to start a three-game series through Saturday."

Fullerton is 18-13 after losing two of three games last weekend at UC Santa Barbara.

Vanderhook took over the Titans program in 2012, when four-year head coach Dave Serrano left for Tennessee. Vanderhook was 36-21 in his first season and followed up with a 51-10 record in 2013, which tied the mark for the fourth-most wins in program history. Fullerton won 66 games in 1984, 60 in '79, 57 in '95 and 51 in '82, all under Augie Garrido.

Fullerton won its postseason regional last year before losing to eventual national champion UCLA in the super regional.

The Titans won the College World Series in 1979, '84, '95 -- with Garrido at the helm -- and 2004 under George Horton. Fullerton has 12 other CWS appearnces.
