Jeff Banister of the American League Texas Rangers and Joe Maddon of the National League Chicago Cubs won Manager of the Year honours in voting results announced on Tuesday.
Both managers steered their teams to dramatic, unexpected turnaround seasons.
Maddon, a two-time winner of the American League award while managing the Tampa Bay Rays, directed the Cubs to 97 wins, 24 more than in 2014, for the third-best record in Major League Baseball and a wild card berth in the playoffs.
Banister, in his first season as a major league manager, oversaw an improvement of 21 games to 88 victories that gave the injury-hit Rangers the AL West title.
