Gee — a fiery competitor and a clown — became a favorite in Detroit. His antics earned him the moniker "The Madman from Mississippi." He hit.300 or better in five of his first seven seasons. Though regularly among the league leaders in stolen bases, he could also be inattentive and overzealous on the basepaths. He once tried to steal a base during an intentional walk. In the 1934 World Series, he was picked off first while arguing with the Cardinal bench. Earlier that year, on June 30, he was picked off base twice in the same inning. After Hank Greenberg singled, Walker reached on an error but was caught off base when the catcher threw to first. Greenberg tried to draw a throw by running to third base and was thrown out, with Walker taking second base. Moments later, with Walker standing six feet off the bag, the pitcher threw to second base and Walker was tagged out. Detroit manager Mickey Cochrane was so angered by Walker's inattention that he suspended Walker for 10 days and fined him $20. In 1936, Walker hit.353 — the highest batting average of his career and 6th highest in the American League. He also hit 55 doubles — second only to his teammate Charlie Gehringer. In 1937, Walker began the season on fire. On Opening Day, he hit for the cycle — the only player to accomplish that feat on Opening Day. He did it in reverse order – starting with a home run, followed by triple, then a double and finally a single. He continued his hot hitting with a 27-game streak in April and May, and his fast start put him in the 1937 All-Star Game, although he did not appear in the game. He ended 1937 with a career-high 18 HR, 113 RBIs and.335 average. Despite Walker's strong performance that year, the Tigers traded him after the season. They sent two of their most popular players, Walker and Marv Owen, to the White Sox for Vern Kennedy, Tony Piet and Dixie Walker. The trade caused an uproar with Tiger fans, and owner Walter Briggs was forced to issue an announcement from his Miami home that "the deal was made with my approval." Walker continued to hit well for several years afterward, but was traded four more times. In December 1939, he was traded to the Washington Senators for Pete Appleton and Taffy Wright. In December 1940, he was traded to the Boston Red Sox for Doc Cramer and then sent to the Cleveland Indians. While playing for the Cincinnati Reds in 1942, in the second game of a doubleheader against the St. Louis Cardinals on May 30, Walker collided in the outfield with fellow Mississippi native Harry Craft, and both were unable to finish the game. Their injuries led to the major league debut of Clyde Vollmer the next day.
Later years
After retiring as a player, Walker served for a year as a coach for the Cincinnati Reds, in 1946. Walker died in 1981 at Mississippi State Hospital in Jackson, Mississippi, at age 73 after a long illness. He was survived by four sons, a daughter and two brothers, one of whom, Hub Walker, was also a former major league outfielder, with Detroit and Cincinnati.
