the Dodgers to omit the Pirates from their spring training schedule. Nonetheless, after the transfer, the Dodgers remained successful under O'Malley: they won the National League pennants in 1952, 1953, 1955—the year of their first World Series championship—and 1956. Under O'Malley, the Dodgers were the most overtly political post World War II franchise. In 1951, Brooklyn native and United States Congressman Emanuel Celler's Judiciary Committee investigated whether the reserve clause was in violation of federal anti-trust laws. Celler represented half of Brooklyn in Congress and O'Malley used the local press such as the Brooklyn Eagle to pressure Celler into backing off of the issue. During the 1951 season, the Dodgers engaged former West Point varsity baseball player and U.S. Army General Douglas MacArthur to lure war veterans. O'Malley attempted to entice him to take the post of Commissioner of Baseball. After the 1956 season, O'Malley sold Ebbets Field to Marvin Kratter and agreed to lease the stadium for three years. Robinson had been a Rickey protege, and O'Malley did not have the same respect for Robinson that Rickey did. O'Malley referred to him as "Rickey's prima donna". Robinson did not like O'Malley's choice for manager, Walter Alston. Robinson liked to argue with umpires, and Alston rarely did so. Robinson derided Alston in the press. In 1955, Alston played Don Hoak at third base during the exhibition season. Robinson voiced his complaints to the press. Robinson did not get along with Bavasi either, and the three seasons under Alston were uncomfortable for Robinson. Robinson announced his retirement in Look magazine after the 1956 season. The signing of Robinson brought the team international fame, making O'Malley an international baseball ambassador to celebrities such as Iraq's King Faisal II. In 1954, Dodgers scout Al Campanis signed Sandy Koufax in large part for two reasons, according to a memo to O'Malley that said "No. 1, he's a Brooklyn boy. No. 2, he's Jewish." Bavasi noted that "there were many people of the Jewish faith in Brooklyn." During the 1955 season, Dodgers catcher Roy Campanella had a medical billing controversy regarding neurosurgery services by Manhattan doctor Dr. Samuel Shenkman. Shenkman billed $9,500, an amount which Campanella forwarded to the Dodgers and the Dodgers refused to pay. O'Malley felt the doctor was overcharging: "It appears that [Dr. Shenkman] thought he was operating on Roy's bankroll..." The Dodgers had convinced Campanella to have the surgery after enduring
