The future Hall of Famer was 47 years old when the Cubs got him in 1970.
He will be remembered for his great knuckleball, and his outstanding career as a reliever. When he retired he held the record for most games and wins in relief, and was the first relief pitcher to be named to the Hall of Fame.
He won't, however, be remembered for his days with the Cubs.
He pitched in three games for them, amassed a very impressive ERA of 9.82, and was traded after the season to the Braves. He is still the oldest player ever to play for the Cubs.
(Here's a little bit of Trivia about Hoyt: He hit a home run in his first major league at bat, and never hit another one in 21 major league seasons)
