Cerv signed with the New York Yankees in 1950 and was a little-used reserve outfielder on the perennially World Series-bound Yankee teams of the early 1950s. According to sportswriter Robert Creamer, interviewed for the Ken Burns series Baseball, one afternoon in 1956, Yankees manager Casey Stengel approached Cerv in the Yankees' dugout, sat down nearby, and commented, "There's not many people that know this, but one of us has been traded to Kansas City." However, this sequence of events did not really happen.[a] In fact, Cerv was sold for cash to the Kansas City Athletics on October 15, 1956, five days after the Yankees had ended the 1956 World Series with a Game 7 victory over the Dodgers at Ebbets Field. By the 15th, the dugouts and clubhouse at Yankee Stadium had all been emptied and the players returned home.
Cerv prospered as a regular in Kansas City. His best season was 1958, when he hit .305, hit 38 homers, and had 104 RBIs. He was elected to the American League All-Star team, beating out Ted Williams for the starting spot. He also finished fourth in the MVP voting that year. He did all of this while playing injured part of the season. He followed up in 1959 with 20 homers and 87 RBIs. On August 20, 1959, Cerv hit three home runs against the Boston Red Sox in an 11–10 loss.
In May 1960, Cerv was traded back to the Yankees for Andy Carey.[2] During that year's spring training, Cerv participated in the TV series Home Run Derby, where he defeated Frank Robinson. Following the 1960 season, he was drafted by the Los Angeles Angels in the expansion draft and was in the starting lineup for the Angel franchise's inaugural game on April 11, 1961.[3] In May 1961, he was traded back to the Yankees,[4] where he was a substitute and pinch hitter. In June 1962 he was sold to the Houston Colt .45s,[5] who released him in August.[6]
During the 1961 season, Cerv lived in a $251-per-month (equivalent to $2,559 in 2023) apartment in Queens with Mickey Mantle and Roger Maris.[7]
^It is possible, however, something was in the works involving moving Cerv to Kansas City at the very end of the 1956 season, where Stengel could have let Cerv know that a sale had been agreed to take place between the two clubs once the post-season ban on such transactions expired.
