Marder, Longley bolster Longhorns coming off record 39th Men’s College World Series appearances
AUSTIN, Texas — University of Texas head baseball coach Jim Schlossnagle announced the additions of assistants Jack Marder and Caleb Longley to his staff on Wednesday morning.
Marder will work with the Longhorns' hitters and catchers, as well as serve as the program's recruiting coordinator, while Longley will assist with Texas' hitters and team defense.
Widely regarded as one of college baseball's top assistant coaches and premier recruiters, Marder arrives on The Forty Acres after spending the past seven seasons at Oregon.
He has been recognized by D1Baseball as one of the '100 Assistant Coaches Athletic Directors Should Know' and one of the '25 Assistants Most Ready to be Head Coaches.' Marder was also tabbed to the '10 of the Hottest Assistant Coaches Names in College Baseball' list by Baseball America.
During his tenure in Eugene, the Ducks compiled a 249-124 (.668) ledger. Oregon qualified for the NCAA Tournament in each of Marder's six full seasons, advancing to the super regionals in 2023, 2024 and 2026.
The six consecutive postseason appearances are the longest streak in school history, besting the four-year run from 2012 to 2015. The Ducks won a pair of conference championships, claiming the 2023 Pac-12 Conference Tournament crown and 2025 Big Ten Conference title.
"Jack is quite simply one of the best coaches and recruiters in college baseball," Schlossnagle said. "His incredible success at Oregon on the recruiting trail speaks for itself. He's a tremendous evaluator of talent, an outstanding teacher of the game and someone who connects with players in a meaningful way. Whether it's recruiting, player development or helping build the culture of a team, he has proven he can push programs to new heights. We're thrilled to welcome Jack and Scout to Austin."
Under Marder's tutelage, Oregon established 19 single-season school records, highlighted by its 115 home runs and 438 RBI in 2025. The Ducks also set 11 career records, including new marks in runs, hits, homers, RBI, slugging percentage and on-base percentage.
He mentored 12 MLB Draft picks, 14 All-America honorees and 32 All-Conference selections at Oregon.
"First and foremost, I want to express my sincere gratitude to everyone at the University of Oregon," Marder said. "To Coach Mark Wasikowski, the players, coaches, administrators, alumni and fans — thank you for believing in me and allowing me to be a part of something incredibly special. The relationships we built and the experiences we shared will always mean a great deal to me. I wouldn't be standing here today without the people who invested in me throughout my journey, and I'm forever grateful for the impact they've had on my life, both personally and professionally. ...
"At the same time, I couldn't be more excited and honored to join the University of Texas. The opportunity to work alongside this great staff is one that I don't take lightly. They are tremendous coaches, leaders and people, and I'm grateful for the trust they've placed in me. Texas baseball is one of the premier programs in all of college athletics. The tradition, the expectations, the passionate fan base and the standard of excellence are unmatched. Those expectations aren't intimidating — they're exactly what drew me here. I came to Texas with one purpose: to help this program win a national championship. Every decision we make, every relationship we build and every day we step on the field will be driven by that goal. I'm excited to pour everything I have into our players, this University and this community. Thank you to everyone who made this opportunity possible. My wife and I are incredibly grateful to be here. We can't wait to get to work."
Prior to returning to Eugene, he spent two years as an assistant coach at Stanford. Marder assisted with nearly all aspects of the program, working with the Cardinal's hitters and catchers, while serving as the team's first base coach as well.
In his final campaign, Stanford finished 45-14, posting the fifth-highest winning percentage (.763) and third-fewest losses in school history.
Marder helped develop nine student-athletes chosen in the 2019 MLB Draft, headlined by backstop Maverick Handley. Handley claimed Pac-12 Conference Co-Defensive Player of the Year distinction, pacing the league in pickoffs (9) and stolen bases caught (13).
Before his stop on The Farm, Marder was an assistant coach for one season with the Keiser Seahawks. At Keiser, he led the squad's recruiting operations and coached third base. The Seahawks made their first-ever NAIA World Series appearance, punctuated by a conference championship and a school-record 43 wins.
Marder was also a volunteer assistant and the director of camps at Purdue in 2016. He started his coaching career as an undergraduate assistant at Oregon in 2015-16, while completing his degree in political science.
The Calabasas, Calif., native played four years of professional baseball in the Seattle Mariners organization, including two seasons at Double-A. Marder heard his name called in the 16th round of the 2011 MLB Draft following two standout campaigns at Oregon.
An innovative baseball mind with a reputation for player development, Longley returns for his second stint on The Forty Acres after a six-month run as a minor league hitting instructor for the Cincinnati Reds.
Previously, he spent one season as the recruiting coordinator and assisted with the hitters at Texas A&M. In his lone campaign in College Station, Longley comprised the fourth-best transfer portal class nationally, according to D1Baseball. Offensively, the Aggies mounted 95 home runs, which ranks fourth all-time in school history. First-round pick Jace LaViolette headlined nine players selected in the 2025 MLB Draft, marking the most for the program in nine years.
Prior to his tenure at Texas A&M, Longley worked three seasons on the Longhorns' staff. He served as the coordinator of hitting and pitching development in his first campaign before being elevated to hitting coach ahead of the 2023 season. Longley was also tabbed the program's recruiting coordinator in 2024.
"We are excited to welcome Caleb and Demi back to Austin," Schlossnagle said. "Caleb brings a wealth of experience and knowledge as one of the game's brightest young coaches. He played a significant role in some of the most successful offensive teams in Texas baseball history, and he understands the standard of excellence that comes with wearing this uniform. He has a tremendous passion for player development and is deeply invested in helping student-athletes reach their full potential. I'm excited for the impact he'll have on the growth of our players and the continued success of our program."
Throughout his time at Texas, the Longhorns produced three of their four highest home run totals in school history. In 2022, Texas smashed the program-record with 128 home runs, surpassing the 2010 club that hit 81 homers. The Longhorns delivered 112 home runs and 91 blasts in 2023 and 2024, respectively.
With Longley's assistance, the 2022 Longhorns also slugged .550 to break the previous school-record of .508 set in 1974. During that historic season, Ivan Melendez became the first Longhorn to win the USA Baseball Golden Spikes Award and swept the national player of the year accolades. Melendez hit a program-record 32 home runs, surpassing Kyle Russell's Texas-record 28 homers in 2007 and Kris Bryant's BBCOR era mark of 31 blasts in 2013. He batted .387 and paced the country with 94 RBI and an .863 slugging percentage. Behind the most prolific power-hitting team in school history, the Longhorns advanced to the College World Series, logging a 47-22 ledger.
In 2023, Longley guided six offensive players to Big 12 All-Conference plaudits, including three first-team honorees. Every regular set a new career-high in homers and five players reached double-digits after returning only two starters and just 23 home runs from the previous year. As a team, Texas batted .293 and averaged over seven runs per game. Despite featuring an almost entirely new lineup, the Longhorns came up just one game short of advancing to their third-straight College World Series.
The 2024 Longhorns made their fourth consecutive NCAA Regional appearance, and the team smacked 112 home runs, the second-most in program history. Outfielder Max Belyeu had a breakout sophomore season, tallying a .329 average, 18 homers and 53 RBI to earn Big 12 Player of the Year recognition. Leadoff man Jared Thomas led the squad with a .349 mark and 61 scored before hearing his name called in the second round of the MLB Draft.
As a recruiter, Longley inked a top-3 signing class in 2024, according to Baseball America. He also helped lay the foundation for Texas' No. 1-ranked group in 2025, landing eventual National Freshman of the Year Anthony Pack Jr., Brett Crossland and Brody Walls.
"I'm incredibly grateful to Coach Jim Schlossnagle for the opportunity to return to The Forty Acres," Longley said. "I have tremendous respect for the way he leads a program and develops both players and coaches, and I'm excited to be a part of it. I'm looking forward to working alongside such an outstanding staff, including the opportunity to reunite with Troy Tulowitzki. I'm eager to get to work, build meaningful relationships with our players and do everything I can to help this program compete for championships."
Longley began his college baseball coaching career at Arizona State, tutoring 2020 No. 1 overall selection Spencer Torkelson and fellow first-rounder Alika Williams. The Sun Devils earned an NCAA Tournament bid in his first campaign before the COVID-19 shortened season the following year.
A native of Cleveland, Tenn., Longley also has experience as a quarterback trainer, working with several NFL and NCAA Power Four signal callers. He was heavily involved with the draft preparation for the late Dwayne Haskins in 2019 and Jalen Hurts in 2020. Longley developed custom arm care, arm strengthening and activation regimens used by NFL and NCAA quarterbacks across the globe.
Additionally, he was the former owner and founder of High Intent Training, a baseball player development center in Nashville, Tenn.
An accomplished Division I player at East Tennessee State, Longley registered 43 career home runs. As a senior, the First Team All-Southern Conference nod slashed .310/.400/.655 with 14 home runs, 20 doubles and 50 RBI. Longley finished his playing career professionally with the Bloomfield Beavers.
