GREGORY STREET
Regional Supervisor of Umpires
I'm proud to bring more than 30 years of baseball officiating experience at the professional and collegiate levels. As a 26-year veteran of the Wake County Sheriff's Office, I have served as an umpire, clinician, and evaluator, with professional assignments ranging from Class A through Major League Baseball.
At the collegiate level, I have worked extensively in NCAA Division I baseball, including more than 20 years in the Atlantic Coast Conference (ACC) and 10 years in the Southeastern Conference (SEC). My postseason experience is also worth mentioning that includes 3 College World Series, 20 Super Regionals, 24 Regionals, and more than 25 ACC and SEC conference tournaments.
Having stepped away from my on-field umpiring career, I'm committed to dedicating my experience and leadership to strengthening the Triangle Umpires Association through education, training, evaluation, mentorship, and professional development.
My vision is (and will continue to be) to build an association grounded in professionalism, accountability, consistency, communication, and a commitment to excellence, while providing dependable, qualified officials to the schools, stakeholders and athletic programs it serves.
Outside of baseball, I have been married to my wife, Uneida, for 35 years. Together, we have two daughters, Lauren and Kayla, and are proud grandparents to our grandson, Kayden.
Our Leaders.
Our clinic leaders are experienced high school umpires who run the Triangle Umpires Association’s preseason training. Each spring before opening day, they lead classroom and on-field sessions covering NFHS rule changes, umpire mechanics, positioning, timing, and game management, from handling a tough call to dealing with coaches. New umpires get hands-on instruction and mentoring to build confidence before their first assignment, and veterans sharpen their skills and stay consistent with association standards.

JIM
COZART
Jim Cozart has been working as a baseball umpire since 2018. He began his umpiring in city baseball and steadily worked his way up, gaining valuable experience at multiple levels of competition. Throughout his umpiring career, Jim has officiated city baseball, travel ball, high school baseball, and American Legion baseball. He also had the opportunity to work one year at the college baseball level, along with summer assignments in the Old North State Wood Bat College League. While working college baseball, Jim attended a two-man umpire developmental camp and a rules development camp. Both experiences provided valuable instruction, strengthened his understanding of the college game, and helped him significantly improve his skills and performance on the field. Outside of baseball, Jim has been employed with the North Carolina State Employees Credit Union Operations Center, Card Services Group, since 2008. His professional experience has helped develop his communication, teamwork, leadership, and problem-solving skills. Jim takes pride in continuing to improve as an umpire, learning from every game, and maintaining a strong commitment to professionalism, consistency, and integrity on the baseball field.

DEREK
DUIN
I started umpiring in 2021 with the Triangle Umpires Association. After my sons graduated from high school, I thought that this would provide me the opportunity to stay involved with high school baseball. I have had the opportunity to be assigned playoff games the past two seasons. During the summer, I enjoy working in this region's American Legion games and the collegiate Old North State League. I enjoy the challenge and learning from some of the best umpires in the TUA.

EVAN
KIRK
Evan began umpiring in his local recreational baseball league in 2018 while in graduate school at the University of North Carolina. An official in three high school sports, Evan had the privilege of umpiring both the 2026 5A East Regional Championship and the NCAA Division II 2026 Conference Carolinas tournament. His growth in baseball is thanks to his mentors in the high school and college game, the support of his wife and family, and his passion for learning. To Evan, being a good steward of the game is most important, including effective game management and strong rules knowledge. Evan looks forward to being a mentor to future umpires and his most anticipated game is the next one.
