Junior Umpire of the year

  • Rick Strom began coaching for the ASMBA in 1982. He spent omst of the following twenty-eight summers volunteering in numerous roles for the leagues. He began umpiring in 1984 and soon took over as Umpire in Chief. This was a time (before mobile phones), where the UIC phoned umpires to schedule them upcoming games. Hundreds of hours of organizing were involved.
  • Rick was a strong advocate for the young umpires in the league. He spent many summer nights (when not coaching) visiting and mentoring umpires. He strongly create better ball players, and developed stronger members of a growing town.
  • Rick encouraged young umpires to be professional, knowledgeable, confident, have integrity, and respect all aspects of the game. These skills were instilled in many young men and women who now give back to the game and the communities in which they live.
  • Rookie & Mosquito coaches will provide feedback on umpires to me each week those who do a good job and consistently demonstrated what Rick wanted to see umpires and those who do not.
