Ken Kaiser officiated in the World Series in 1987 and 1997, as well as the All-Star Game in 1991. He also umpired in the American League Championship Series in 1980, 1988, 1993 and 1995 (Game 6), and in the American League Division Series in 1981, 1996 and 1997. He also worked the single-game playoff to decide the AL West champion in 1995. On May 6, 1982, he was home plate umpire for Gaylord Perry's 300th career victory. Kaiser wore this cap during his umpire career. The hat shows solid use and Kaiser has added his signature to the sweatband of the hat. Nice signed relic from Kaiser's umpire career!!! JSA authenticated signature.
