Don Larsen, the only pitcher to toss a perfect game or no-hitter in MLB World Series history, died Wednesday at the age of 90.

On Monday, October 8, 1956, In Game 5 of the 1956 World Series, Larsen retired all 27 Brooklyn Dodgers batters he faced at Yankee Stadium for a 2-0 win. I had the privilege of interviewing Larsen for the “Postseason Perfection” chapter of my book Baseball’s No-Hit Wonders, and it is one of my all-time favorite interviews.

Larsen’s accomplishment was the first no-hitter in Mlb Postseason History. When I asked Larsen how he felt when Roy Halladay tossed a no-hitter in the 2010 NLDS (the second in MLB postseason history), he replied, “It didn’t bother me a bit. It was the playoffs. That wasn’t a World Series game, anyway.”
