The weather started out as rain before turning to sleet and, eventually, snow, forcing the umpires to call the game in the middle of the fourth inning.
During a third-inning delay the Royals also played video of a fireplace on the center-field video board to try to evoke warm thoughts for fans.
Some players, such as Kansas City's Alcides Escobar and Mike Moustakas, raced onto the tarp and did a slide into second base through the snow. Others, like Royals right-hander Luis Mendoza -- a native of Veracruz, Mexico -- snapped a picture of the surprising May weather.
