1957 – The Kansas City Athletics ship pitchers Art Ditmar, Bobby Shantz, and Jack McMahan, and infielders Clete Boyer, Curt Roberts and Wayne Belardi to the Yankees. In return they receive pitchers Mickey McDermott, Tom Morgan, Rip Coleman and Jack Urban, OF Irv Noren, plus infielders Billy Hunter and Milt Graff. Roberts will not go to New York City till May 4th, while Boyer goes a month later, conveniently just when his mandatory service time in the majors as a result of the bonus rule expires. Hunter and Urban don’t switch until April 5th. The veteran Shantz and Boyer will be valuable pick-ups for New York, with Shantz leading the American League in ERA this year, and Boyer a tough defensive 3B for eight years in pinstripes. The A’s will eventually admit that when they signed Boyer for a $40,000 bonus in 1955, it was on behalf of the Yankees, with the understanding that they’d ship him to NY as soon as he became eligible to be sent down to the minors.
