Quinlan was killed in an auto accident after leaving a golf outing during spring training of 1965.

He was an avid golfer, and a charity golf tournament in his name has been held in the Chicago area ever since.

Quinlan's classic call of the final out of Don Cardwell's no-hitter on May 15, 1960, transcribed from a phonograph record of Cubs history issued in 1971, is quoted below.

(Wrigley Field crowd roars) ... Cunningham's arguing now... he's back here barkin' at Tony Venzon, the plate umpire... he's really sore... he is really peeved at that strike two, that was called... One more pitch could end it... You know what kind of a pitch we're hopin' for: The dark one!

Two audio books "Jack Quinlan/Forgotten Greatness" Parts I and II were produced by broadcaster Ron Barber and include every known remaining clip of Quinlan's play-by-play and are part of Barber's continuing effort to gain Quinlan consideration for election to the Baseball Broadcasters' Hall of Fame.
