Post assists in all the day-to-day duties for the softball team, including recruiting and travel and on the field, she primarily works with the infield, pitchers and catchers.

Post has a spectacular resumé, having started out her college career at Central Arizona College where she was a second-team Arizona Collegiate College Athletic Conference selection as a sophomore. She played catcher, third base and shortstop at Central Arizona.

The former Haley Torrez finished her college career at Boise State University, starting both years for the Broncos. She spent her senior year at catcher and third base, hitting .273 with 23 RBI. She completed her stellar college career in the top ten for career slugging percentage as well as on-base percentage.

She also played professionally overseas in Therwil, Switzerland before accepting a position on the coaching staff at Kansas Wesleyan University in 2016. There, she was a graduate assistant for a semester before taking over as head coach for the 2017 season, helping the Coyotes to a 71-33 record in her two seasons.

Hailey is married to Matt Post, who is a firefighter for Bexar County and the pair are expecting their first child in March, 2022.
