The Yankees transferred Don Larsen, Hank Bauer, Norm Siebern, and Marv Throneberry to the Kansas City Athletics on December 11, 1959, in exchange for Roger Maris, Joe DeMaestri, and Kent Hadley. Jesse Gonder was purchased by the Yankees from the Cincinnati Reds before to the 1960 season. He made his debut on April 17, 1960, against the Cleveland Indians at Yankee Stadium. Larsen went 21-4 with a perfect game and no-hitter for the Dodgers in 1956. He returned to pitch eight more seasons after being traded to the Yankees. Bauer played first base and batted.275 over nine seasons in New York. Siebern had a good year for the Athletics in 1958 when he hit.302 with 22 homers and 87 RBIs. He was then sent to the Twins along with Billy Hunter to re-sign Carl Yastrzemski. Throneberry spent all or part of six seasons with the Athletics, batting.272 with 19 homers and 102 RBIs. After leaving Oakland, he played two seasons with the Cubs and one with the Pirates before retiring. Gonder went 4-1 with a 3.54 ERA in 46 games (one start) for the Reds. He ended up winning 20 games while losing only five for the Yankees, who released him after the season to make room for him on their roster. The 24-year-old right-hander is still the only pitcher to win 20 games for New York.
