Curt Simmons was the first pitcher Ernie Banks ever faced in the big leagues in 1954. Just eleven years later, on this day in 1965, Ernie hit his 400th career home run against the same pitcher, Curt Simmons.
By the middle of the following season, the two men were Cubs teammates.
Simmons had a great career. He won 193 career games, and a World Series title with the 1964 St. Louis Cardinals, but with the Cubs he only won seven games in parts of two seasons.
