John Aloysius McKeon was born on November 23, 1930 in South Amboy, New Jersey. He is nicknamed Trader Jack, a former manager in Major League Baseball, most recently for the Florida Marlins. When he retired after the 2005 season at age 74, he was the third oldest manager in major league history. McKeon was named National League Manager of the Year in 1999 and 2003. The latter award was a result of leading the Marlins, who had a record below .500 when he took the job as their manager during the season, to a World Series victory. On October 2, 2005, just after the Marlins won the last game of the 2005 season, McKeon announced that he would not be returning the following season. McKeon is also the author of two books, Jack of All Trades and I’m Just Getting Started. He resides in Elon, NC.
