Kansas City Athletics Yearly wOBA Leaders

Below is a list of the yearly wOBA leaders for the KC A's. The number in parenthesis is wOBA+, which is wOBA divided by AL average wOBA for that particular season multiplied by 100. A 111 wOBA+ suggests the player was 11% better than the average AL hitter that season. By this measure, Ramon Webster's .321 wOBA in 1967 was more valuable than Ken Harrelson's .330 wOBA in 1965 since there was less offense in the AL in 1967.

Elmer Valo apparently had the best offensive season in KC A's history in 1955. He had a long, solid career as an outfielder, and put up his best numbers in his one full season in Kansas City. He was rewarded by being cut by the A's early on in 1956.
