Some might say that Opening Week is a time to simply enjoy the return of baseball, to take in and devour all of the new food offerings, to not worry about wins and losses so early in the season.

This gentleman was reacting to a close 2-1 pitch to Matt Carpenter that was called a ball. Carpenter flied out later in the at-bat and, eventually, the Pirates won on a walk-off single in the 11th.
Is it because of that man's passion and will for his team to win? We'll never know for sure, but yes, probably.
