Bob Senff was born in Winnipeg, Manitoba on April 2, 1947. Senff moved to Virden in 1971, and in 1980 he became an umpire. Over the next 30 years, he was a highly respected umpire in western Manitoba. He worked primarily in the Manitoba Senior Baseball League (MSBL), but for two years he also handled games in the Prairie League of Professional Baseball. On top of this, he would regularly umpire at Provincials, Westerns, and Nationals. He even umpired at the first Women’s National Championship held in St. James. Senff served in administrative positions such as Umpire Assigner, Umpire-in-Chief of the MSBL, and as a member of the Disciplinary Committee of Baseball Manitoba. He especially remembers umpiring a senior game in which his two sons played against each other, and a time in the Prairie League where he sang both the Canadian and American national anthems.
