That could be my 2nd favorite Nats win EVER, the first being the Z-man walk-off against the Yanks.
ORIOLES = LAST PLACE TEAM 
This reminds me of the 2005 win against the Cubs - blew a lead in the 9th, blew another lead in the 11th ... and won anyway ... this ranks right up there with that ...
My list
Zim's walk off against the Yankees
Ramon's no/no into the 9th against the Cardinals
Nats comeback from 7 runs down to the Yankees
Zim's walk off against the Marlins
12th inning win against the cubbies in 05
Tonight's win ... right up there ...
