In 1978, Rice won the American League's Most Valuable Player award in a campaign where he hit .315 (third in the league) and led the league in home runs (46), RBI (139), hits (213), triples (15), total bases (406, and slugging percentage (.600). Altogether he led the AL in 11 different categories that year. He is one of only two AL players ever to lead his league in both triples and home runs in the same season, and he remains the only player ever to lead the major leagues in triples, home runs and RBIs in the same season. His 406 total bases at that year is still a Red Sox record, and the most in the AL since Joe DiMaggio had 418 in 1937. it made Rice the first major leaguer with 400 or more total bases since Hank Aaron's 400 in 1959. This feat was not repeated until 1997, when Larry Walker had 409 in the NL. No AL player has done it since Rice in 1978, and his total remains the third highest by an AL right-handed hitter, behind DiMaggio and Jimmie Foxx (438 in 1932).
