Jim Simpson, a Hall of Fame sportscaster who made a mark on ESPN’s early days as its first play-by-play announcer, died Wednesday morning in Scottsdale, Ariz., his family told the sports network. He was 88.

A cause of death was not released. Simpson was admitted to the hospital over the weekend while watching the Washington Redskins playoff game.

Simpson’s long career includes the radio call of the first Super Bowl, in addition to calling the MLB All-Star game 16 times, the Olympics 14 times and the World Series six times. He called six Super Bowls, and served as the NFL’s play-by-play voice for 15 years.

More to come…
