Coming back from a 3-1 deficit to win the World Series was no easy feat for the Chicago Cubs and many still wonder exactly how they were able to pull off such an impossible task.

But now that question has been answered, and you can thank a naked Anthony Rizzo.

According to SI's Tom Verducci, Rizzo gave motivational speeches to his teammates while he was stripped down to his skivvies to help rally his team ahead of the final three games of the Series.

Naked Rizzo quoted "Rocky" among other famous movies, as SI described in this excerpt from Verducci's new book The Cubs Way: The Zen of Building the Best Team in Baseball and Breaking the Curse.

And the rest, as they say, was history. The Cubs went on to capture a thrilling Game 7 victory over the Indians to win their first World Series title since 1908.

Verducci's book will be released March 28 and can be purchased here.
