[3] The stadium consisted of a single-decked, mostly covered, grandstand, extending from the right-field foul pole down and around most of the left-field line.

However, when work began on double-decking the stadium for the A's, it was discovered that three decades of harsh Midwestern winters had weakened the footings until they could no longer support the weight of an upper deck.

The city ran three shifts and the new stadium was built in 90 days, faithful to the original design, completed in time for the 1955 season opener.

The expanded stadium was supposed to seat 38,000, but cost overruns as a result of overtime payments forced officials to reduce capacity to just over 30,000.

Hall of Famers Bullet Rogan, J. L. Wilkinson, José Méndez, Satchel Paige, Hilton Smith, and Willard Brown all played for the Monarchs.

Other Hall of Famers who spent a season or more with the Monarchs include: Cristóbal Torriente, Andy Cooper, Turkey Stearnes, Cool Papa Bell, Bill Foster, Willie Wells, Ernie Banks, and the legendary Jackie Robinson.

[citation needed] After being discharged from the United States Army, Jackie Robinson signed with the Monarchs for the 1945 season.

[8] As one of the Yankees' top farm teams (sharing that status with the Newark Bears for much of the time) the Blues had many great players and successes.

That team was led by Hall of Fame player (and future Yankee Announcer) Phil Rizzuto and Vince Dimaggio, who hit 46 home runs.

[11] Mickey Mantle, Whitey Ford, Ralph Houk, Al Rosen, Billy Martin, Bill Virdon, Johnny Mize and Elston Howard were some of the players in the Yankees farm era who played for the Blues.

Supposedly, Layton's gimmick was short-lived after Finley noticed the vast majority of the "would've been home runs" were being hit by the Athletics' opponents.

In addition to his notorious tinkering with the right-field corner, Finley experimented with moving the other fences in and out several times during his seven seasons operating the team here.

Reggie Jackson, Sal Bando, Catfish Hunter, Joe Rudi and Gene Tenace were some young A's players who debuted in Kansas City and went on to lead them in their World Series victories in Oakland.

[16] Kansas City welcomed the new Royals, who were led by 1969 American League Rookie of the Year Lou Piniella.

[17] In subsequent seasons, many future stars made their debuts for the Royals, who were building a highly competitive team, rising up to an 85–76 record in 1971.

CF Amos Otis (1970), P Paul Splittorff (1970), SS Freddie Patek (1971), 1B John Mayberry (1972) and P Steve Busby (1972) were a core of young Royals who made their debuts at Municipal Stadium.

Temporary stands were erected in left field to expand the stadium's capacity each fall, but had to be removed during the baseball season.

Lamar Hunt himself was the first Chief elected to the Hall, as his role as a league pioneer resulted in pro football growing from 12 to 26 franchises in the 1960s.

[21][22] In one of the great performances at the stadium, the Chiefs' Hall of Fame Quarterback Len Dawson passed for 435 yards and 6 Touchdowns against the Denver Broncos on November 1, 1964.

As AFL Champions under Coach Hank Stram, the Chiefs won Super Bowl IV, beating the Minnesota Vikings 23–7.

[24] Super Bowl IV was the last game played before the merger of the AFL and NFL[25] They moved to Arrowhead Stadium in the Truman Sports Complex for the 1972 season.

[30] Notable players on the rosters included: Hank Aaron, Ted Williams, Mickey Mantle, Willie Mays, Roberto Clemente (His first All-Star Game), Stan Musial, Yogi Berra, Roger Maris, Whitey Ford, Brooks Robinson, Ernie Banks, Eddie Mathews, Bill Mazeroski, Al Kaline, Orlando Cepeda, Nellie Fox and Luis Aparicio.

[31] The date was originally supposed to be an off-day for the band following a concert in New Orleans, but they agreed to perform when Finley offered their manager, Brian Epstein, a then-record sum of $150,000 (equivalent to $1.14 million in 2014).

The neighborhood still contains legendary Arthur Bryant's Barbecue at 18th and Brooklyn Street, founded in 1908, a fan and player favorite when Municipal Stadium was nearby.

Located in the 18th and Vine District, the museum is housed in the former Paseo YMCA building where the Negro leagues were first formed in 1920.
