this guy is bossI don't know anything about your "system", but according to my analysis (which is quite comprehensive d1g1t), you are correct concerning the NATS.
There is one slight problem that will play into this. I make the NATS a -111 favorite and the linesmakers are asking for -130. For me, this game goes at 4:05 (PDT), to I'll factor in the line movement and lineups before I pull the trigger. Early on, there doesn't seem to be enough value for me to get involved, but best of luck with your action.
I'm going to take it for what it's worth and assume that you have no system and are pulling this out of your ass to try and garner some attention.
Regardless, the Nationals seem like the correct side today at first glance.
