I have nothing to say about last night other than that was fun. Some games just everything goes right and you get to enjoy the ride. As to the question whether the offense is started another 20 game run of greatness or not, we'll still don't know. We have to see over the next few games. Let's hope the Brewers pitching sparked something.
It certainly will skew any "Nats averaged X R/G since..." numbers so be aware of that. That's something that we need to understand. The Nats offense looks great in comparison to the league. The 4.45 R/G it averages is 2nd in the NL and even before last night they were in 5th. But we've all watched the team all year and we wouldn't say they have a great or even very good offense. So what gives? It's a distribution thing.
We talked about this some other year - I forget which - when the Nats never seemed to score either 3 or 4 runs in a game, I forget which. It was a weird quirk. We see something similar this year, a team that either is great or terrible.
Scoring 2 or fewer games is pretty much a losing proposition. You win about 17% of your NL games this year when you do this. The Nats have done this 25 times in 2015 tied for third most in the NL only behind Milwaukee and Philadelphia. You might have heard of them. They are the worst and 2nd worst teams in the NL, but not in that order.
On the other hand scoring 7 or more runs in a game is close to a guaranteed win this year. NL teams win about 91% of their games when they manage this many runs. Who is best in the NL? The Nationals of course, tied for first doing it 17 times. (The also have 2 more games than any other NL team scoring 10 or more)
For the games of 3-6 runs, the Nats are dead last in the majors only doing it 23 times. The Nats are essentially all or nothing this year, with more nothing than all. However, this type of team will always look good in R/G because you can score a lot more over the average where as you are stuck at around 3-5 runs under the average because you can't score less than zero.
Here's their rankings of number of times they've scored this many runs in a game.
Shutout : 15th in NL
1 run : 1st
2 runs : 2nd
3 runs : 10th
4 runs : 10th
5 runs : t10th
6 runs : 15th
7 runs : t4th
8 runs : t5th
9+ runs : 1st
What's the take-away? Runs per game is fine to get a general sense of how a team scores or allows runs but not always the best at tying that to a teams fortune. If they don't have an even distribution then it can skew away from what your expectations may be. The Nats so far this year are that type of expectations skewing team.
