Nick Callahan rejoined Case Western Reserve University for his second stint as the Assistant Baseball Coach prior to the start of the 2016 season. Callahan had previously served in the same role for the team from 2010-13.
In his three seasons since rejoining the team, the Spartans have gone 103-56, good for a .647 winning percentage. Callahan's efforts helped the Spartans secure the first outright UAA Championship in program history in 2018, earning him and the rest of the team's coaches the UAA Coaching Staff of the Year award. During the year, Callahan helped coach three All-UAA pitchers in Liam Killingstad, Matt Levine and Ben Murphy. He also helped oversee the development of pitcher Jake Shields, who earned all-region and all-conference honors in both 2016 and 2017. In 2019, Callahan led a pitching staff that recorded the 28th-lowest ERA (3.53) and 22nd-lowest WHIP (1.28) in Division III. He coached both freshman Nick Denove and junior Scott Kutschke to all-region honors during the campaign.
His initial time with the team helped produce one of the most successful stretches in the program’s history, with the Spartans earning a pair of NCAA Championship bids, finishing third at the regional in 2011 and second in 2013. Callahan aided the Spartans pitchers in receiving three all-region certificates, a UAA Player of the Year award, and an All-America honor. In addition, CWRU lowered its staff ERA during each of the three seasons, with each mark the best during a 12-year stretch.
Callahan spent the previous two years as the Assistant Coach and Recruiting Coordinator at NCAA Division II Coker College in Hartsville, South Carolina, where the team posted its lowest ERA over the last 10 years. While at Coker, he earned his Master of Science degree in College Athletic Administration.
Callahan served two stints as the Head Coach of the Geneva Twins of the New York Collegiate Baseball Summer League in 2013 and 2014, while also working as the pitching coach of the Geneva Red Wings in 2011. Prior to that, he served as a volunteer assistant coach with Finger Lakes Community College from 2008-10.
Callahan received his Bachelors’ in Business Administration from SUNY Brockport in 2007.
