On March 30, 1966, famed Los Angeles Dodgers pitchers Sandy Koufax and Don Drysdale ended their double holdout by signing new contracts for $130,000 and $105,000, respectively. Their holdout during Spring Training lasted 32 days.
The two future Hall of Famers demanded a combined $1 million over three years. They fell short of that but ultimately signed for more than what the Dodgers had initially offered to the hurlers.
Although revered for their contributions on the field, Koufax and Drysdale were the subject of plenty of public criticism and frustration from fans. The situation is widely considered the first time players banded together and is credited for altering the economics of baseball.
