All of these team categories in which he led the club were overshadowed by his accomplishments in offensive statistics league-wide. Yastrzemski batted .326 on the season, slugged 44 home runs, and drove in 121 RBIs, which led the American League in all three of these main offensive categories (Yastrzemski was actually tied in the home run category with Harmon Killebrew of the Minnesota Twins). In leading the league in home runs, RBIs, and batting average, Yastrzemski achieved the Triple Crown. Only one Red Sox player in history had reached this milestone—Ted Williams, who did it twice, in 1942 and 1947. It was the second consecutive year that the Triple Crown was achieved in the American League, Frank Robinson having won the honor in 1966 during his first year with the Baltimore Orioles. It took 45 years before another triple crown was won, by Miguel Cabrera of the Detroit Tigers in 2012. In the scope of this season that had begun with low expectations for the Boston Red Sox, the leadership and outstanding batting by Yastrzemski added to the "impossible" feeling that the season overall had overwhelmed the New England region.
