In year three, the RedHawks finished the regular season with a 38-15 overall record and a 25-8 mark in MAC play, surpassing the program's single-season record of 23 conference wins set in 2025. The team also captured its second consecutive MAC regular-season championship, marking Miami Baseball's first back-to-back conference titles since 1973-74. The RedHawks had seven players earn All-MAC honors, highlighted by Tommy Harrison being named MAC Player of the Year and Diego Cruz earning MAC Freshman of the Year honors. Cruz and Marcus Dierks were also recognized on the All-MAC Defensive Team. Harrison was named to the ABCA/Rawlings NCAA Division I East All-Region First Team, while Dierks and Cruz earned Second Team honors. Harrison also received national recognition as an ABCA/Rawlings Third Team All-American, an NCBWA Second Team All-American and a CBF Honorable Mention All-American. Following the season, Miami pitcher Austin Berggren was selected by the New York Yankees in the 12th round of the 2026 MLB Draft.

In year two with the RedHawks, he helped push the team to a regular season and MAC Tournament Championship for the first time since 2005. The RedHawks had seven players recognized as All-MAC in 2025. Evan Appelwick was named a Second Team Academic All-American and Cooper Katskee a Third Team All-American. Miami pitcher Hayden Cuthbertson was selected in the 18th round of the 2025 MLB Draft by the Miami Marlins. The Red and White finished the 2025 season nationally ranked 12th in base on balls (346), 15th in on-base percentage (0.423), 24th in sacrifice flies (33), 34th in scoring (8.2) and 38th in runs (474).

In his first season as an associate head coach with Miami, the team finished with a 17-13 record in Mid-American Conference play, the program's best conference record since 2019. The RedHawks went 27-27 overall, including a nine-game win streak (the best in five years), and advanced to the MAC Tournament for the first time since 2019. Zach MacDonald, Carson Byers and Ryland Zaborowski were named First Team All-MAC selections. MacDonald and Peyton Olejnik were both selected in the 2024 MLB Draft, with Olejnik going to the Angels in the sixth round and MacDonald joining the Tigers' organization in the 15^th round.

Trewyn previously spent time with Bradley University, most recently as associate head coach and recruiting coordinator. His responsibilities also included serving as the team's hitting coach, offensive coordinator, catching coach and third-base coach.

Trewyn's tenure with the Braves included four consecutive winning seasons in conference play for the first time in program history. He helped produce 26 All-MVC players, six MLB Draft picks, one Freshman All-American and the 2017 MVC Freshman of the Year. Bradley hit 58 home runs in the 2022 campaign, the most the team had amassed in a single season since 2001.

During the 2015 and 2016 seasons, Trewyn worked as an assistant coach at Quincy University, where he was the hitting coach, catching instructor, infield instructor and first-base coach. In both years, the Hawks earned the No. 1 seed in the NCAA Division II Midwest Regional. The 2016 squad set program records for batting average (.334), home runs (89), doubles (124), RBI's (483) and runs scored (517) en route to a 39-win season, while the 2015 ballclub won the GLVC Western Division title. Trewyn helped mentor 17 All-GLVC players, including the conference's 2016 Player of the Year, along with two All-Americans.

Prior to joining Quincy, Trewyn was a volunteer assistant at Bradley for the 2013 and 2014 campaigns, serving as catching coach, assistant hitting coach and first-base coach. His first stint with the Braves yielded eight All-MVC players, five Freshman All-Americans, one First-Team All-American and four MLB Draft picks.

Trewyn has also worked as an assistant coach at Minnesota Duluth (2011-12) and his alma mater, Cardinal Stritch (2010-11). He was the head coach of the 2012 Sheboygan A's in the Wisconsin State League, a summer collegiate baseball league.

Trewyn graduated from Cardinal Stritch in 2011 with a Bachelor's degree in History, adding a Master's of Education from Minnesota in 2013.

"I'm excited to get to work at Miami University," said Trewyn. "Coach Smiley and Coach Scully are two guys that I have a lot of respect for and am definitely looking forward to working with. I am very thankful for the opportunity!"

"Kyle is a great hitting coach who I have watched develop young hitters for the past decade," Smiley said. "His passion for hitting is contagious and our current and future players are going to love working with him every day. We are incredibly fortunate to have Kyle joining us here; this is a big win for Miami Baseball!"
