On June 15, 1964, the St. Louis Cardinals make one of their best trades ever, acquiring outfielder Lou Brock from the Chicago Cubs.

In a six-player transaction that also includes Jack Spring, Paul Toth, Doug Clemens, and Bobby Shantz, Chicago trades a little-known outfielder named Lou Brock, who will become a fixture with the Cardinals for the next fifteen years, amassing 3,023 career hits, to St. Louis for right-hander Ernie Broglio. The deal, thought at the time to be a steal for the Cubs, will become infamous when the former 20-game winner pitches poorly for his new team, posting a 7-19 record during his brief two and half seasons with the team,

Brock, will appear in 3 Cardinal World Series, Brock will hit .391, steal 14 world series bases which is tied with Eddie Collins for the all-time lead. The Cardinals will win the titles in 1964, 1967 and lose in 1968. Brock will also become all-time single-season leader and career leader in stolen bases. Brock will be elected into the Hall of Fame in 1985.
