1971 season for 1969 NL Rookie of the Year Ted Sizemore and young catcher Bob Stinson. Allen had a relatively quiet season in 1971 although he hit .295 for the Dodgers. Chicago White Sox Allen was acquired by the White Sox from the Dodgers for Tommy John and Steve Huntz at the Winter Meetings on December 2, 1971. For various reasons, his previous managers had shuffled him around on defense, playing him at first base, third base, and the outfield in no particular order – a practice which almost certainly weakened his defensive play, and which may have contributed to his frequent injuries, not to mention his perceived bad attitude. Sox manager Chuck Tanner's low-key style of handling ballplayers made it possible for Allen to thrive, for a while, on the South Side. Tanner decided to play Allen exclusively at first base, which allowed him to concentrate on hitting. That first year, his first in the American League (AL), Allen almost single-handedly lifted the entire team to second place in the AL West, as he led the league in home runs (37) (setting a team record), RBI (113), walks (99), on-base percentage (.420), slugging percentage (.603), and OPS (1.023), while winning a well-deserved MVP award. However, the Sox fell short at the end and finished games behind the World Series–bound Oakland Athletics. Allen's feats during his years with the White Sox – particularly in that MVP season of 1972 – are spoken of reverently by South Side fans who credit him with saving the franchise for Chicago (it was rumored to be bound for St. Petersburg or Seattle at the time). His powerful swing sent home runs deep into some of cavernous old Comiskey Park's farthest reaches, including the roof and even the distant () center field bleachers, a rare feat at one of baseball's most pitcher-friendly stadiums. On July 31, 1972, Allen became the first player in baseball's "modern era" to hit two inside-the-park home runs in one game. Both homers were hit off Bert Blyleven in the White Sox' 8–1 victory over the Minnesota Twins at Metropolitan Stadium. On July 6, 1974, at Detroit's Tiger Stadium, he lined a homer off the roof facade in deep left-center field at a linear distance of approximately and a height of . Anecdotal and mathematical evidence agreed that Allen's clout would've easily surpassed on the fly. The Sox were favored by
