Lucas Giolito did not pitch well yesterday. He had trouble throwing stirkes and when he did he was hittable. In my opinion, that's how he pitched in his first game too, but the Mets never challenged him to throw strikes and the rain delay kept him from pitching deeper into the game. This is something the 21 year old will have to work through, and given his pedigree he will do it. Eventually.
Prospects are prospects. The occasional one makes his mark immediately. Kris Bryant. Noah Syndergaard. But far more often they take time to be impactful, if it even happens. The higher the prospect the better the odds of both immediate and long term impact, but by no means is it guaranteed. So when you look at Giolito and Turner don't assume they are going to be great, or even good, this year.
What should the Nats goal for the series be? I am aiming for a split. I like to keep a "series" lead ahead of the second place team. Three games so that entering each new typical series it would take a sweep by them and the Nats getting swept to fully lose the lead before the natural reset a new series takes place. A split or better (which is now limited to 3-1 win) would keep that type of lead. The commenter said one win would be enough and I can see that. Having a two game lead coming out of this, is not ideal, but is far from disastrous.
The same names are struggling at the plate. Zimm, Robinson in his place, Werth. But for the most part this recent stumble bumble has been pitching related. Ross, Gio, middle relief. I keep saying this but it keeps being true - these things happen. As long as it doesn't' become a systemic issue you just have to roll with it. Wait for the 2nd and 3rd starts, the 2nd, 3rd weeks of relief pitching.
