In 1953, Maxwell turned things around, playing the full season for Louisville of the Triple-A American Association, and finishing the year with a .305 batting average, 23 home runs and 107 RBIs. Maxwell's strong performance in Louisville and Williams' broken collarbone resulted in Maxwell being the Red Sox starting left fielder at the start of the 1954 season. In mid-May, Williams returned to the lineup, and Maxwell, to the bench. In the off-season, the Red Sox sold Maxwell to the Baltimore Orioles, but Maxwell had only four at-bats for the Orioles before being sold to the Detroit Tigers on May 9, 1955. Peak years with Detroit (1956–1960) Maxwell remained with the Tigers from 1955 to 1962, serving as the teams' regular left fielder from 1956 to 1960. After being platooned in Detroit's outfield in 1955, the 1956 season was Maxwell's first as an every-day player, and his performance won him a spot on the 1956 American League All-Star team. Maxwell played 141 games for the Tigers in 1956 and finished among the American League leaders in most batting categories with a .534 slugging percentage (3rd in the AL behind Mickey Mantle and Ted Williams); a .326 batting average (4th in AL); a .414 on-base percentage (4th in the AL); 96 runs (4th in the AL); 28 home runs (5th in the AL); and 87 RBIs (5th in the AL). Maxwell also excelled in the field in 1956, with a .987 fielding percentage. He often gave a pregame show for the fans, especially on Saturdays when the Tigers hosted kids from the "Knothole Gang." "Shagging fungoes in left field, Maxwell would grin, clown around, and catch the ball behind his back or between his legs." ("Charlie Maxwell," by Jim Sargent) At age 30, Maxwell followed up with another strong season in 1957, winning a spot on the American League All-Star team for the second straight year. Having committed only four errors in 1956, Maxwell improved his performance in 1957, committing only one error in over 300 chances. He led all AL outfielders with a .997 fielding percentage. And his 2.36 Range factor in left field was 0.39 points above the average for all outfielders. Maxwell also continued his strong hitting in 1957. Though his batting average dipped by 50 points to .276, he finished with a .377 on-base percentage (8th in the AL), .482 slugging percentage, 24 home runs (7th in
