Trevor Hairgrove completed his second season as the Cougars Director of Operations after working the 2019 season with Brian Green at New Mexico State as the volunteer assistant coach where he helped with the offense and defense, and also served as the first base coach. Hairgrove also served as an assistant coach, working with the Cougar hitters, infielders and catchers during the 2021 season.
Â
Hairgrove added on-field coaching to his duties during the 2021 season and helped Green guide WSU to its first winning season since 2015 and the most Pac-12 Conference wins since 2014 after posting conference series wins at Utah, at California, against No. 8 Oregon and Washington. In the classroom, WSU posted a program-record 3.09 GPA in the fall semester as 30 players recorded a GPA of 3.0 or higher and 17 players earned Pac-12 Spring Academic Honor Roll honors. The Cougars also signed his second-straight nationally ranked recruiting class for the 2022 season including the best junior college class in the country according to JBB baseball.
Â
In 2021, the Cougar offense led the Pac-12 and fifth in the country in doubles-per-game (2.4), second in the conference in hitting (.302), third in extra-base hits (101) and third in scoring (7.2 runs/g) while pacing the league with 74 doubles in conference games. First baseman Kyle Manzardo was named to the All-America First Team by Collegiate baseball, earning All-America honors for the second straight season after hitting .365 with 19 doubles, 11 home runs and 60 RBI, the first Cougar with 60 RBI since 2008.
Â
The Cougars produced three draft picks in 2021 led by two-time All-American Manzardo who was selected in the second round and No. 63 overall by the Tampa Bay Rays, the highest Cougar draft pick since 1991. Manzardo was joined by Zane Mills (4th round, St. Louis) and Brandon White (12th round, Miami) to give WSU three draft picks in the first 12 rounds for the first time since 1977. Three players earned All-Pac-12 Conference honors as Manzardo and designated hitter Tristan Peterson were named the All-Pac-12 team while catcher Jake Meyer received honorable mention, the first Cougar catcher to earn all-conference honors since 2013.
Â
The Cougars were limited to just 16 games, including the first 11 on the road, in 2020 due the COVID-19 pandemic but saw WSU post impressive numbers on and off the field. Green and his coaching staff focused on building a culture as the Cougars connected with the Pullman community, volunteering with a number of organizations including the Salvation Army and Whitman County Special Olympics. In the classroom, 22 players posted a fall semester GPA of 3.0 of higher and the team combined for a 3.05 team GPA, the highest team GPA in program history.
Â
The culture the coaching staff created in the fall carried over into the spring as the Cougars recorded a series win over Rutgers in Arizona, the first series-win over a Big Ten Conference opponent in program history, and followed with a four-game series sweep of Niagara at Bailey-Brayton Field. On the recruiting front, WSU signed the fifth-ranked junior college recruiting class led by a Preseason Junior College Two-Way Player of the Year and also signed four of the Top-10 high school prospects in the state of Washington.
Â
In 2019, the New Mexico State offense finished the regular season with a school-record .356 batting average and led the country in batting average, runs, runs per game, hits, triples, on base percentage, slugging percentage and hit by pitch. Individually, shortstop Joey Ortiz was named the WAC Player of the Year, a semifinalist for the Brooks Wallace Award (best shortstop in the country) and Dick Howser Award (best player in the country) while second baseman Nick Gonzales was also a semifinalist for the Howser Award and the Golden Spikes Award (national player of the year).Â
Defensively, the Aggies posted an impressive .974 fielding percentage a year after breaking the single-season school record with a .977 clip in 2018. Off the field, the Aggies earned the NMSU Athletics Community Service Award for the fourth straight year in 2019 and set the program attendance record for the fourth time since 2015.
Hairgrove worked the previous three seasons (2014-16) at his alma mater UC Riverside including the final season as the team’s director of baseball operations, overseeing the team’s travel while assisting with the scouting reports.
Â
During the summer season from 2014-17, Hairgrove also worked as a field manager for the Rochester Honkers of the Northwoods League. He was in charge of recruiting players for the summer league team and helped run the offense serving as the third base coach. IN 2016, Hairgrove mentored and coached Drew Ellis, the 44th overall selection in the 2017 MLB Draft. The summer of 2017 saw him help the offense lead the league in home runs and sit at third in walks at season’s end. He also coached the 2017 Northwoods League MVP, Zack Zubia.
Â
Following a stellar four-year playing career at UC Riverside, Hairgrove was selected in the 18th round, 555th overall, by the Los Angeles Angels of Anaheim. The 2011 season saw him start in 52 games for the Orem Owlz before moving up to Low-A ball with the Cedar Rapids Kernels in 2012. In 2013, Hairgrove progressed to High-A as a utility player with the Inland Empire 66ers before being promoted to Double-A in the middle of the season.
As a student-athlete at UC Riverside, Hairgrove started 200 games at shortstop which puts him at fourth all-time in school history for career game started. He was named First-Team All-Big West and to the ABCA All-West Region team in 2011. Hairgrove earned his bachelor’s degree from UC Riverside in 2014.
