McKeon rejoined the Marlins on June 20 on an interim basis after Edwin Rodriguez resigned as manager following a 1-18 slump that left the team with a division-worst 32-40 record.
McKeon, 80, is the second-oldest manager in Major League Baseball history behind Connie Mack, who ran the Philadelphia Athletics at 87 in 1950. Florida went 39-48 since McKeon’s return and is 71-88 with three home games remaining against the Washington Nationals.
McKeon won the World Series in his only playoff appearance in 16 years as a manager. With a 1,050-988 career record, he managed the Marlins from 2003-05 and also led the Kansas City Royals, Oakland Athletics, San Diego Padres and Cincinnati Reds.
Nicknamed “Trade Jack” as a player-swapping general manager in the 1980s, McKeon said this season that his return this year made him a role model to seniors, motivating them to stay active and even to get back to work.
“You ought to see the mail I get from older people,” he said in an interview. “It’s inspiring that they tell me I’m inspiring them to do something, to get involved.”
