Billy Martin "Yankees MGR 4 Times #1" Signed OAL Baseball. Billy Martin set the record for most times managing the Yankees. The hot-headed but talented Martin managed the New York Yankees five different times between 1975 - 1988, an era peppered by fights with opposing players, his own players, and a marshmallow salesman. But there was success on the field, including a World Series title in 1977. He was actually hired one more time after signing this ball and would soon after die in a tragic car accident. Martin was very proud of his accomplishments as Yankee's skipper and he took the time to emphasize that on this ball, it is signed "Billy Martin, "Yankees MGR 4 Times, #1". The OAL ball is heavily toned throughout. Overall this is an amazing Martin ball and represents an entire era of Yankees history. Includes LOA from JSA.
