In what year was Hank Aaron intentionally walked 3 times?

Answer 1

He was walked intentionally three times in 1975, when he was 41 years old and a shell of the player he used to be:

Even at his peak, though, he was never walked intentionally more than 23 times in a season. Quite a difference from Bonds, who walked intentionally 120 times in 2004! Different eras and different approaches, I guess.

Answer 2

1975

Answer 3

1975, his next to last year.
