Fans encouraged to show off must-see moments with MLB's THIS campaign

Local and national media alike had been talking about Stephen Strasburg for a long time. The hard-throwing right-hander was set to make his major league debut against the Pirates. And he did not disappoint. He struck out 14 Bucs over seven innings en route to his first win. THIS electric stuff was even greater than what many expected.

While celebrating the Nationals' 10th season, new commissioner Rob Manfred headed to D.C. to announce the exciting news that Nats Park will host the 2018 All-Star Game. THIS national stage is what D.C. was hungry for.

On the last day of the 2014 season, Jordan Zimmermann took the mound. As the game went on, the regulars behind him were replaced by bench guys and September call-ups. But it didn't matter. Capped with an amazing catch by Steven Souza Jr. for the last out of the season, Zimmermann had the Nats' first-ever no-hitter. THIS is the greatest performance in Nationals history.
