Four? Kinda. Royals Stadium hosted the MLB game in 1973. The 2012 game was held in a newly-updated Kauffman Stadium. The old Municipal Stadium was the host park for both the 1960 Major League game and the 1962 Negro Leagues East-West All-Star Game. One Royals + one Kauffman + two Municipal Stadium = 4.

Though hosted in KC, Billy Butler was the only Royal in the game. He was passed over for the Home Run Derby (Thank You, Robinson Canó). Billy grounded out in the 7th inning and struck out swinging as the second out in the bottom of the 9th.

The Royals had several big names on the roster: Amos Otis, John Mayberry and Cookie Rojas. Mayberry and Otis made 3 of the 5 hits for the American League. Future Royals manager Buddy Bell (at the time a Cleveland Indian) played; he hit a triple in the 3rd inning. It was Willie Mays’ 24th (and final) All-Star Game. The stadium opened to the public on April 10 that year and the All-Star Game was on July 24–a mere 106 days. Kansas City fans would wait nearly 39 years to host another.

Negro Leagues East-West All-Star Classic
Eastern players (from the Birmingham Black Barons and Harlem Stars) and Western players (from the Kansas City Monarchs and Memphis Red Sox) played the last East-West game. Major League Baseball continued to diversify and hire talent away from the Negro Leagues and they folded (for that, financial and other reasons) at the close of the 1962 season. A pregame ceremony honored Jackie Robinson, Frank Duncan, Newt Allen and Satchel Paige–all former Kansas City Monarchs.

This was one of two All-Star Games in 1960. Another was played two days later at Yankee Stadium. Two games are better than one, right? Most of the proceeds from both games went to the [then] undercapitalised player’s pension fund. The two-game format lasted from 1959-1962. After the pension fund was righted, owners dropped the second game. Critics said it watered down the impact of the “All-Star” experience, never had consistent dates or locations and became little more than unseemly profiteering. Perhaps those four extra games made a difference after all. Major League Baseball’s current pension system is the envy of other professional sports.
