5. Scherzer vs Pirates: Max Scherzer was one out away from a perfect game against the Pittsburgh Pirates on June 20th in the nation's capital when he hit since-DFA'd outfielder Jose Tabata with a slider inside that spoiled his bid for perfection.
Scherzer stayed focused and retired the next batter to complete his first and the Nats' second no-hitter since they returned to Washington in 2005 and the fourth no-hitter in D.C. baseball history.
Throwing a no-hitter was impressive enough, but throwing one against a talented team like the Pirates impressed his manager.
