Joe Maddon was voted the National League (NL) Manager of the Year by the Baseball Writers' Association of America.
After leading the Cubs to their most regular-season wins since 1945, Maddon received 18 first-place votes (124 points) to become the fourth Cub to win Manager of the Year.
"It's staggering, actually, to do it twice in the American League then to get it in the National League and be a part of this wonderful Cubs organisation," Maddon told MLB Network after the selection was announced.
The St Louis Cardinals' Mike Matheny finished second with 12 second-place votes and 87 points, followed by the New York Mets' Terry Collins with 49 total points.
The Texas Rangers' Jeff Banister beat out the Houston Astros' A.J. Hinch and the Minnesota Twins' Paul Molitor for American League (AL) Manager of the Year.
Banister led the Rangers to an 88-74 record and their first play-off appearance since 2012, taking 17 first-place votes and 112 total points.
Hinch finished second with eight first-place votes and 82 overall points, ahead of Twins manager Paul Molitor (33 points).
