The following year, Rodriguez took over as the Mariners' regular shortstop and led the American League (AL) with a .358 batting average, the highest for an AL right-handed batter since Joe DiMaggio hit .381 in 1939 and the 3rd highest ever for a shortstop. He also had 36 home runs with 123 RBIs. At 21 years and one month, he was the 3rd youngest AL batting leader ever behind Al Kaline (20) in 1955 and Ty Cobb (20) in 1907, and the 3rd youngest player in history with 35+ homers. He was also the first major league shortstop to win a batting title since 1960, and the first in the AL since 1944. At age 20 years, 11 months, he was the youngest shortstop in All-Star Game history. He also led the AL in runs (141), total bases (379), and doubles (54) and ranked among the league leaders in base hits (2nd, 215), extra base hits (2nd, 91), multi-hit games (3rd, 65), slugging (4th, .631), RBI (8th, 123), and on-base percentage (8th, .414). Rodriguez posted the highest totals ever for a shortstop in runs, hits, doubles, extra base hits, and slugging, and tied most total bases, and established Seattle club records for average, runs, hits, doubles, and total bases, in a season that statistical analysts consider the best ever by a shortstop.
