Derek Jeter Still Haunted By Yankees' 2004 Postseason Collapse

Eighteen years ago today, the Boston Red Sox achieved the impossible. They completed the biggest comeback in baseball history, erasing a 3-0 deficit to defeat the New York Yankees in seven games in the 2004 ALCS.

Two decades later, Derek Jeter still isn't over it.

On ESPN's new series "The Captain," which premiered in July, Jeter reflected on one of the worst moments of his Hall-of-Fame career.

"It's misery," Jeter said, looking back. "Sick to my stomach...I didn't sleep well for a while."

The stunning defeat was devastating for Jeter, who was regarded as one of baseball's winningest players. Blowing a commanding lead and watching New York's biggest rivals celebrate on the field at Yankee Stadium was a nightmare for one of the sport's fiercest competitors.

Boston went on to sweep the St. Louis Cardinals in the World Series, leaving Jeter and the Yankees to wonder what might have been if they'd been able to finish off the Red Sox.
