Bulldogs Baseball Camps

Coaching Staff

Kiel Kreidermacher
Assistant Coach

Kiel Kreidermacher, who was a fixture at shortstop for the University of Minnesota Duluth during the late 1990s, reconnected with the Bulldogs just prior to the 2018 season by taking on an assistant coaching role.

A native of Mendota Heights, Minn., Kreidermacher was member of the UMD baseball program from 1995-99 (he was redshirted as a first-year freshman) and handled a starting role during each of this final three seasons. As a senior, he helped lead the Bulldogs to the Northern Sun Intercollegiate Conference championship and was a teammate of current UMD head coach Bob Rients.

Kreidermacher, who helped coach the Hermantown Legion/VFW teams from 2008-14, owns a B.S. degree in accounting from UMD (2009).


Kevin Folman
Post Graduate Intern

Another addition to the Bulldog coaching staff for 2018-19, Kevin Folman closed the books on a rewarding four-year career at North Dakota State University this past May, posting the second-most saves (15) in program history. The two-time Bison team captain and 2018 All-Summit League second team selection went on to pitch for the Sioux Falls Canaries.  After a short stint with that American Association of Independent Professional Baseball club, Folman had his contract purchased by the Chicago White Sox on July 25th. He subsequently was assigned to the Arizona Leagues' White Sox before moving on to the Great Falls Voyagers (Pioneer League). In his eight appearances with those two rookie league franchises, the Hermantown, Minn., native made seven starts and went 2-3 with a 4.35 earned run average over 39 1/3 innings.

A Summit League All-Academic Team pick as a junior and a senior, Folman graduated from North Dakota State in May 2018 with a B.S. degree in mathematics education.


Daniel Hersey
Assistant Coach

Daniel Hersey, who has assembled an impressive coaching resume over the past dozen years, has been added to the UMD staff for the 2018 season.

Hersey served as both the manager (2010-17) and director of baseball operations (2011-17) with the Duluth Huskies, directing them to Northwood League playoff appearances in 2013 and 2015. Prior to coming to the Twin Ports, he spent time in an assistant coach/recruiting coordinator role at the College of Central Florida (2009-11) and Saint Leo University (2005-08). Hersey also was the pitching coordinator for the All-American Prospects travel team out of Vero Beach, Fla., during the summer of 2009 and the manager for the Coastal Plain League's Wilmington Sharks one year earlier. Hersey's collegiate playing experience includes stints at the University of West Georgia (2003-04) and Rollins College (2000-03). Last spring, he assisted with the Proctor (Minn.) High School baseball program.

Hersey received a B.A. Degree in psychology from Saint Leo University in 2005.


Coach Erickson
Volunteer Assistant Coach

Tyler Erickson, who enjoyed a record-breaking baseball career at the UMD, has returned to his alma mater in 2018-19 to serve as an assistant coach.

A native of Alexandria, Minn, Erickson started four years at shortstop for the Bulldogs and exited the UMD program in 2011 as its all-time leader in both hits (237, a mark that has since been eclipsed) and defensive assists (458). As a junior, Erickson topped the Bulldogs in hitting with a sizzling .452 batting average en route to attaining Daktronics All-America (honorable mention), National Collegiate Baseball Writers Association All-Central Region (second team), Rawlings/American Baseball Coaches Association All-Central Region (second team), Daktronics All-Central Region (first team), Rawlings/American Baseball Coaches Association All-Central Gold Glove (second team) and All-Northern Sun Intercollegiate Conference (first team) recognition. He also cobbled together a a school-record 29 game hitting streak that spring while playing in 56 outings (another program mark).

Erickson, who graduated from UMD with a Bachelor of Science degree in criminology in 2011, is currently employed by St. Louis County as a Youth in Action program coordinator. He and his wife Mandy, have two children -- daughter Riese and son Tate.
