In Major League Baseball, the Manager of the Year Award is an honor given annually since 1983 to the best managers in the American League (AL) and the National League (NL). The winner is voted on by 28 members of the Baseball Writers Association of America (BBWAA). Each places a vote for first, second, and third place among the managers of each league. The manager with the highest score in each league wins the award.

Several managers have won the award in a season when they led their team to 100 or more wins. Lou Piniella won 116 games with the Seattle Mariners in 2001, the most by a winning manager, and Joe Torre won 114 with the New York Yankees in 1998.Tony La Russa and Sparky Anderson finished with identical 104–58 records in 1983 and 1988, respectively. Three National League managers, including Dusty Baker, Whitey Herzog, and Larry Dierker, have exceeded the century mark as well. Baker's San Francisco Giants won 103 games in 1993; Dierker's 1998 Houston Astros won 102 and Herzog led the Cardinals to 101 wins in the award's third season.

Edward Mosley was the second major American trader to arrive in Kansas in the late 1850s, following the arrival of A. J. Greenway in 1852. Mosley arrived with a companion surnamed Moxley, and the two built a trading "ranche" near the intersection of the Osage Trail and the Big Arkansas River, 14 miles northwest of the present location of Wichita.

The pair's substantial trading projects ended with the onset of the American Civil War. Mosley took to waylaying straggling Confederate soldiers and was eventually drowned while attempting to cross the Kansas River with stolen livestock. Mosley was killed by a group of Osage Nation and Cheyenne.

Mosley has a street named after him in downtown Wichita, so named by James Mead, who admired Mosley most out of all frontier traders. Mead described him as "a large, strong man with clear blue eyes and locks of black hair dangling to his shoulders - the most perfect specimen of physical manhood I ever saw."
