The walk-off homer is one of the most exciting moments in the game -- as long as you're a fan of the team doing the walking off. Nats star Bryce Harper is one of the most exciting players in the game, more than capable of capitalizing on potential walk-off situations. This scenario played out to perfection on Saturday, as Harper's booming blast off Edubray Ramos turned a 4-4 tie into a dramatic 6-4 Nats victory over the Phillies. It was also basically an exclamation mark from Harper, who agreed with the club on a contract for 2018 earlier in the day. A pretty solid Saturday for Bryce, but it also extended a particularly eventful few days for D.C. sports in general. It came less than a day after John Wall's thrilling, season-extending three pointer in Game 6 of the Eastern Conference Semifinals propelled the Washington Wizards into a winner-take-all Game 7 against the Boston Celtics.
