The Saint Louis Cardinals and Kansas City Royals each have fewer than 50 games to play this season. Both teams hope to win enough games to play for the championship of North American baseball later in the year. The Cardinals and Royals have a long-standing rivalry. It is sometimes called the “Show-Me Series.” That is because both teams play their home games in the American state of Missouri, known as the “Show-Me State.” This week, the Cardinals and Royals have been playing against each other in a series of games. But it is not the usual “Show-Me Series” rivalry that people are talking about. Instead, they are talking about a new battle that took place during the game Wednesday night. The battle was between a member of the Cardinals’ field crew and a cat.
