Texas Tech assistant coach Kristie Fox is leaving the Red Raider staff after being named the head coach at UT Arlington.

The 26-year-old Fox becomes one of the youngest Division I head coaches in the country after helping guide Texas Tech to three-straight trips to NCAA Regional’s.

"I couldn't be happier for Kristie," Texas Tech head coach Shanon Hays said. "She will have a lot of success at UTA as she is a great teacher of the game and a solid recruiter. For her to be named a head coach at her age, it says a lot about the state of our program and she has played a huge part in that. We wish her absolutely nothing but the best."

Fox worked primarily with infielders and hitters over her three years on the staff. During that time the Red Raiders broke nearly every offensive school record while also setting a new mark for fielding percentage this past year.

"I want to thank Coach Hays, Aly Sartini, the Texas Tech Athletics Department, and the Tech players for three great years and the opportunity to coach in the Big 12," Fox said. "I have enjoyed my time in Lubbock and have learned a lot and am looking forward to taking my knowledge and experience to UTA."

Offensively Texas Tech boasted one of the top line-ups in the country in each of the last two seasons, setting a school and Big 12 record in 2011 with a .341 team batting average. The Red Raiders combined to go 121-51 over Fox’s three seasons.

Hays will begin a search for Fox's replacement immediately with her successor being named later this summer.
