Knapp hit a pinch-hit, walk-off, upper-deck home run in the 13th inning. It doesn't get much better than that.

Watch: Phils' Andrew Knapp crushes walkoff, upper-deck home run in 13th


Phillies catcher Andrew Knapp hasn't hit many home runs in his young career, six to be exact, but he may never hit a more memorable one than he hit Sunday.

Entering the game as a pinch-hitter in the bottom of the 13th inning, Knapp crushed Nationals reliever Justin Miller's fastball into the second deck at Citizens Bank Park. 

Final: Phillies 4, Nationals 3. And a memory that Knapp will never forget.

What makes the situation somewhat bizarre is that when Knapp stepped to the plate with one out as a pinch-hitter for reliever Nick Pivetta, the Phillies had no one up in their bullpen. They had already used nine pitchers in the game, and really, who do you bring in at that point?

In his third MLB season, Knapp is hitting .221 with three home runs in 104 at-bats.
