Justin Seely
- Title:
- Assistant Coach/Recruiting Coordinator
Oklahoma State added Justin Seely to its coaching staff as an assistant under head coach Josh Holliday in June 2021.
Seely joined the Cowboys after spending the previous 12 seasons on the coaching staff at Texas A&M.
“Justin has excellent people skills, an outstanding skill set both on the recruiting trail and on the field of play. He is a winner," Holliday said. “I look forward to the impact he will have in our players’ lives and the awesome student-athletes he will help us attract to Stillwater. He is a perfect fit with our program’s values and knows what it takes to win at the highest level of college baseball.”
Seely's impact was felt in the program during his first season in Stillwater. After helping OSU sign a recruiting class ranked fifth nationally by Collegiate Baseball, he helped lead the Cowboys to 42 wins, their most since 2016. The Pokes earned a No. 7 national seed in the NCAA Tournament, the fourth time Seely has been part of a nationally-seeded team, and the Regional berth was Seely's 14th in 15 seasons as an assistant coach.
The 2022 Cowboys improved offensively in a number of categories, including posting a .298 batting average, their highest since 2010, and a .400 on-base percentage, their best since 2008. OSU ranked in the top 20 nationally in walks, doubles, hits and runs and also recorded a .978 fielding percentage, the third highest in program history.
Seely helped coach All-Americans Jake Thompson, Nolan McLean and Justin Campbell and Freshman All-American Roc Riggio in 2022, and OSU saw a program-record seven players selected in the top 10 rounds of the Major League Baseball Draft.
OSU's recruiting efforts under Seely continue to pay dividends as the incoming recruiting class for 2023 was ranked No. 8 nationally by Baseball America and the 2023 transfer portal class came in at No. 15 nationally in the Baseball America rankings.
During Seely’s time at Texas A&M, the Aggies averaged 42 wins per season, made 11 NCAA Regional appearances, advanced to four Super Regionals and played in two College World Series (2011 & 2017). They also claimed four conference championships, three as a member of the Big 12 and one SEC crown.
Seely served as the TAMU recruiting coordinator and will maintain those duties at OSU.
During Seely’s time in College Station, he helped sign a top 25 recruiting class every year, including five top-10 classes, and he was ranked eighth nationally among all recruiting coordinators by D1Baseball.com in 2016.
The Aggies had at least one player earn All-America honors in each of the last seven years and counted 21 All-Americans during his time in College Station.
Seely has coached 11 players in his Division I coaching career who have played in Major League Baseball, and he has signed and helped develop five first-round MLB Draft picks. From 2012-19, TAMU had the second-most players selected in the MLB Draft among all NCAA programs with 52.
In 2016, Texas A&M set a record for MLB Draft picks in a season with 13. That group helped the Aggies claim their first-ever SEC championship with an offense that hit .311 and averaged over seven runs per game.
Prior to joining the staff at Texas A&M, Seely spent the 2008 season as an assistant at Texarkana College, served two seasons as a volunteer assistant at his alma mater, Nebraska, in 2006 and 2007, and was on the staff at Paris Junior College from 2004-05.
A native of Nacogdoches, Texas, Seely’s collegiate playing career began at Northeast Texas Community College, where he spent two seasons before transferring to Nebraska.
In two seasons with the Cornhuskers, Seely made 87 starts as an outfielder and DH and hit .355 with 11 home runs and 65 RBIs and helped lead NU to the first two College World Series appearances in program history. As a senior in 2002, he hit .320 with 19 doubles, seven homers and 37 RBIs.
Seely earned his degree in history from Nebraska in 2003. He and his wife, Tara, have a son, Slade, and two daughters, Sydney and Shelby.
