Gio Gonzalez went 3-0 with a 0.95 ERA in three starts against Miami last season, all at home. He's 4-2 with a 1.76 ERA in six career matchups. Nats went 9-1 at home last year against Marlins. Miami is off to a nice start, and I expect them to come back to earth here a bit as they've yet to play a team with a winning record this year.
