Even while in the midst of a four game slide the Nats are 11 games over .500 and leading the NL East. Over the next two days they will have the pitchers with the second and the third highest WAR in the NL on the mound. By all accounts this losing streak should end within the next two games, but it could have and perhaps should have ended last night. If it had been Detwiler on the mound instead of Chien-Ming Wang the Nats losing streak may already be over.
The problem with Chien Ming Wang has nothing to do with him. This has been his pattern over the last couple of seasons. He comes back from injury and takes a bit of time to get right, and when he does he is a good and sturdy pitcher that can go deep into games. Right now his delivery is off and he is overthrowing everything and leaving his sinker up in the zone where it is getting hit and hit hard.
