A peek into the laboratory ...
Here are some things the Nats Blog Research & Development team are working on. First, we're close to releasing ERV charts for pitchers, now that we have a fair amount of games for them. Here's a look at Esteban Loaiza's:
Compare to Chad Cordero's:
The one thing to notice about Cordero's: he has earned positive RV/WV in EVERY game in which he has appeared this year, except for one. Even in his blown save, he went on to pitch another inning or two to make up for it a bit. And we all know about his close calls. Truly remarkable.
Finally, here's a chart showing the Nats cumulative Win Value for last night's game. Essentially the higher the line goes above 0.00, the better chance the Nats have at winning the game (and vice versa for below the line). This chart shows how comfortable the win was last night.
