Don Denkinger, who worked as a Major League umpire for nearly 30 years, died Friday at the age of 86.

Denise Hanson, one of Denkinger’s three daughters, said he died at Cedar Valley Hospice in Waterloo, Iowa.

"Today MLB remembers longtime American League Umpire Don Denkinger, who passed away at 86," MLB Communications posted to Twitter Friday. "The genial Denkinger was on the field from 1969-1998 and worked four World Series, the last of which included plate duties for the epic Morris-Smoltz Game 7 in 1991. Rest in Peace, Don."

While Denkinger worked four World Series, he is unfortunately known for a call he got wrong in Game 6 of the 1985 World Series.
