After graduating from Wendelstedt School in Florida during its 2011 course, Rehak journed through Minor League Baseball's Gulf Coast, Appalachian, Florida Instructional, Midwest, California, Eastern, Arizona Instructional, International, and Arizona Fall Leagues before earning an invitation to Major League Spring Training as well as a sleeve number assignment of #35 in 2018 alongside fellow Pennsylvanian and MLB staff member Jansen Visconti, whom MLB hired in early 2020.
Rehak has 13 ejections through his three years of call-up service and was named the UEFL's Fill-In Umpire of the Year in 2020, having previously won the same award in 2018.
News of Rehak's hire was first reported by the Wendelstedt Umpire School on Facebook and leaves a temporary overfill on the staff as MLB has yet to officially announce a corresponding retirement. Not many winters go by with excess staff on payroll, though.
