Khris Davis has had the same batting average for four consecutive years. Have other batters with 100 or more plate appearances in each year done this?
Reading the article, there is only one other player who managed to have the same batting average for 3 consecutive years. **Mookie Wilson, with .276 from 1983 to 1985.
So I don't think there is another player with 4 or 3 years aside from the listed here (Khris Davis & Mookie Wilson) with the same batting average.
