Nearly four hours after opening pitch, the best sound in baseball rang out at Nationals Youth Academy Field in Southeast Washington. 

The loud collision between Michael Campbell's aluminum bat and the baseball signified many things. It meant, very clearly, that a home run had been hit. It meant that the game was over after 12 draining innings. It meant that St. John's had just won its fifth consecutive Washington Catholic Athletic Conference championship. And it meant that in about two minutes, the field would be covered with discarded hats, tearful parents and long, sweaty hugs. 

Campbell's walk-off, two-run home run gave St. John's a 6-4 victory over DeMatha in an extra-innings thriller Sunday. It was the second shocking homer in a game with enough highs and lows for an entire season.

"I really don't have any words to describe what happened today," St. John's Coach Mark Gibbs said. "As a player and as a coach, that was the best game I've ever been a part of."
