UC Santa Barbara earned its first trip to the College World Series in one of the most dramatic endings college baseball fans will ever see.

Sam Cohen crushed a walk-off grand slam in the bottom of the ninth to defeat No. 2 national seed Louisville on the road.

This is real...

Seriously, how did Cohen pull that off?

To put it into a little more perspective, Louisville was a perfect 47-0 this season when leading after eight innings and Cohen had one home run all year. But the freshman pinch-hitter went toe-to-toe with one of the nation's best closers to send his team to Omaha.
