The Nats did what they needed to, taking 3 of 4 from the Phillies. Anything less would have started the season not only a depressing 5-8, but with a losing record against a team the Nats, injured or not, should roll over. It would have also increased the Mets lead to 5 games. Every game counts.
A lot of other things happened - here's my quick takes
Span is back! Great! I've never been convinced Span was a good offensive player. Last year strikes me far more as a lucky peak year than a transformation to a bat you want in your line-up. But still Span is not a bad bat and I like him much better in the field. Even if Taylor is a great fielder Span has advantages it would take Taylor at least months to catch up to. He knows the speed of the major league game. He knows the opponents. He knows the different parks. Most importantly, he knows what Bryce and Werth can and can't do (and they know the same about him). We've seen that lack of familiarity cause break downs in the outfield. That shouldn't keep happening now.
Taylor goes down! To me this is another "future" move when a present one would make more sense. The best 4th OF the Nats have is Michael Taylor. There should be no doubt about that. You can make a case that you want him to get regular at bats, but to me regular AAA bats hold no value for Taylor anymore. Keep him up. Get Werth (injury risk) and Span (injury risk) a day off every 4th game or so. Give Bryce (injury risk) a game off every couple weeks. In the end Taylor would be playing every other/every third game. Make this team as good as possible. Don't worry about making 2016 maybe a tiny tiny bit better (and probably not)
Yuney goes down (in another sense)! Yunel Escobar has been fluky good early on. That wasn't going to last. But he could be average or very slightly above. Why not? He hopes to be back on Tuesday and he very well might be. MRI showed no issues other than slight inflammation and for everyone but Anthony Rendon that usually works out pretty quickly. But let this be another warning shot across the bow for you. This entire offense, save Ian Desmond, is an injury risk. It's hard for me to consider any of these guys "mild" risks either. It's a precarious situation that makes winning when they are mostly healthy (like now) paramount.
Strasburg pitched great. This should not surprise you. He's a very good pitcher.
Zimmermann pitched poorly again. Is it velocity (it's down a bunch after years of stability)? Is it location (issues throwing strikes past two games)? Is it stuff failing (K's are down a ton)? I don't know. I'd give it one more start. The Red Sox game was a game where he didn't have it - he was hit hard. The Phillies game? That was more control issues and some bad luck. Desmond doesn't boot another one, Galvis' broken bat flare doesn't fall in and it's 2 runs in 6 1/3 despite the walks and no one is really concerned.
The Mets suffer two big injuries. Jerry Blevins caught a ball on the arm and broke it. Catcher D'Arnaud broke his hand. The latter could be a quick recovery - depends on the break. The former will be a couple months at least. Wright is already out. So the Nats got 'em right? Well we only have to look back to the 2012 Nats to see that isn't the case. Morse missed 60 games. Werth half a season. Ramos barely played at all. Storen missed half the season. The Nats still managed to win 98 games. If the Mets rotation stays intact and they get some luck with injury replacements, they'll be fine... meaning they could be trouble.
