Little bit of trivia: Andy Pettitte used to play for Potomac. Back then it was called the Prince William Cannons and they were a New York Yankee affilliate. This is actually where the cannon name eminated - as the logo was a civil war cannon (Yankees in civil war).
Prior to becoming the Cannons they were the Prince William Pirates - to which our favorite baseball player of all time Mr. Barry Bonds played. That's right - Barry Bonds played part of his young career in Woodbridge, VA. So stop hating him! LOL.
