Question: what is the highest single season batting average in mlb history?
Answer: Hugh Duffy, who played from 1888 to 1906, is credited with the highest single-season batting average, having hit .440 in 1894. The modern-era (post-1900) record for highest batting average for a season is held by Nap Lajoie, who hit .426 in 1901, the first year of play for the American League.
