Chicago Cubs president of baseball operations Theo Epstein knows first-hand that a 3-0 deficit in the League Championship Series isn't insurmountable.

The Cubs executive was, of course, the general manager of the Boston Red Sox when they stunned the New York Yankees in the ALCS in 2004, becoming the first team in history to win the series after dropping the first three games. The Red Sox would go on to sweep the St. Louis Cardinals for their first World Series title since 1918.

Epstein and his Cubs now find themselves in a similar position after their 4-2 loss Tuesday to the New York Mets.

"Rumor has it it's been done before," Epstein told reporters.
