Maxwell achieved an odd measure of success as a player who hit especially well on Sundays. And for a five-year stretch (1956-60), he also hit well on most of the other days. Maxwell finished 1956 with 28 HR (fifth in the AL) and set career highs by batting .326 (fourth) and slugging .534 (third). The Tigers had made him a regular that season for the first time in his career; his performance earned him a starting spot on the All-Star team.
Maxwell’s batting average slipped in later seasons but he retained his power, with four 20-HR seasons. In 1959 he tied for fourth in the AL with 31 HR and was fifth in RBI with 95. He averaged nearly 72 walks a year in his five seasons as a regular, and as a left fielder led AL outfielders in fielding in 1957 and 1960, showing good range.
