Sano has immediately impacted the Twins lineup by hitting 14 home runs and driving in 41 runs since he was promoted from Double-A Chattanooga on July 2.
His production exploded in August as the 22-year-old Dominican Republic native homered nine times, a rate which over the course of a full season would put him on pace for 54 home runs.
His .611 slugging percentage on the season meanwhile is third-best in Twins history.
Sano had his first career multi-homer game on Aug. 12 against Texas. He also homered in six of his final 12 games in August, including in back-to-back games on Aug. 17-18 and Aug. 23-25.
Sano leads AL rookies this year in on-base percentage (.403) and slugging percentage (.608). The only other right-handed hitters with higher slugging percentages during their age-22 season are Hall of Famers Joe DiMaggio (.673 in 1937) and Jimmie Foxx (.637 in 1930).
