Nationals trail Braves 3-0 through four (Werth homers now 4-1)

The Nationals and Braves have played four innings in Atlanta, and Chien-Ming Wang is having one of his rougher starts in recent memory. His inability to drive his sinker down in the strike zone has been at the heart of the problem.

He grooved a changeup to Brian McCann, who blasted it to right for a homer in the first inning. In the second, Wang couldn’t get a sinker to drop, and Chipper Jones took him deep to right. And in the fourth, he left another fastball up to Jones, who ripped it to right for a double. He’s allowed

Wang’s sinker has been precise on some occasions and rough on some others, and he’s probably not going to be back at full strength until next year. It’s clear he isn’t completely consistent yet with the sinker, though he’s used it to great effect several times this season. As much as Wang throws the pitch (more than 70 percent of the time, and on 48 of 55 pitches tonight), it’s got to be on for him to have success. So far tonight, it hasn’t been.

Update: Jayson Werth hit a solo home run off of Tim Hudson in the top of the sixth inning putting the Nationals down 3-1.
