Don't get fooled by Washington winning nine in a row. Not when it comes to the run line. If the Nationals were laying 1 1/2 runs, they would be 3-7 in their last 10 games.



Arizona is trying to avoid a sweep and has a pitcher who thrives in situations like this. The pitching matchup is southpaws Wade Miley against Gio Gonzalez.



In comparing the two, Miley has the better numbers. He's 5-3 on the road with a 2.86 ERA. He is 4-1 in day games with a 2.75 ERA. He has a lifetime 2.59 ERA in four starts versus Washington. The Diamondbacks are 7-2 in Miley's last nine road outings versus opponents with a winning record.



Arizona has a better road mark than home record. The Diamondbacks are 7-2 in their past nine games against a left-handed starter.



Gonzalez is struggling with an 0-5 mark and 5.20- ERA in his past seven starts. His home ERA is 4.67. His daytime ERA is 4.50 compared to 3.57 at night.
