On Saturday night, something unexpected happened in an important baseball game.

The St. Louis Cardinals were playing against the Boston Red Sox in the World Series.

The World Series is a best-of-seven series. That means the first team to win four games wins the World Series and is named the best major-league baseball team of the year.

The games are always filled with tension and excitement, but Saturday’s game—game three—had a bit more of both.

It was the bottom of the ninth inning.

The game was tied 4-4.

It was the last chance for the Cardinals to score a point. If they did, they would win the game.

What happened next was very exciting.
