They are a fantastic palate cleanser. If the Nats manage to win tonight will the Brave losses still sting? OK, they will, but as bad?
I'm assuming the Nats can score a few runs on Sanabia (sure he shut out the Mets last time out - but (1) he put on 10 guys in 6 innings and struck out one, & (2) the Mets aren't the Nats) Tonight it's all about Haren. He was OH MY GOD bad in game one, and merely run of the mill bad in game 2. He's given up 19 hits in 9 innings, 9 of those for extra bases. His only saving grace has been that he's walked none. The Marlins are terrible at scoring. They've managed 1.67 runs per game so far. If Haren can't do something as simple as 6IP, 3 runs... well then it may be time to officially worry.
Anything else? Not really. Just for notes purposes - using the Pythagorus W-L right now is useless because big losses (or wins) will have too big an influence as well as quality of opponents faced so far. These things get smoothed out over time. If you must at least remove the largest win and loss from the Nats record and figure out the rest. (they are more 7-6 than 6-7, would be results of that).
Also for those worried about attendance, now that they've had a weekend series (where they averaged 38K) they are out of the bottom area. Still not where they should be but this should show you what a weekend series vs a marquee team can do for the numbers. Now don't look at it again until June!
