The Nationals will get to use the designated hitter over their next three games at Safeco Field. Manager Matt Williams had a pretty easy choice for the first DH. He wanted to rest Jayson Werth, who is playing on a sore right ankle, and he wanted to give Nate Schierholtz his first start with the Nationals. And so, Werth is the designated hitter and Schierholtz is playing right.

“He’s a good defender out there,” Williams said. “He’s certainly comfortable playing out there. It gives us an opportunity to get him in the game. It takes a little bit of pressure off Jayson, too, with his ankle. It’s a logical move for us.”

Williams is not sure who will DH the rest of the series. Right-hander Chris Young, a former member of the Nationals’ organization, was slated as the Mariners’ scheduled starter. But they switched their rotation and changed Saturday’s starter to left-hander Elias Roenis. Williams said that could change his thinking with the DH.

Werth likes being DH. “I like it a lot, actually,” he said. In his career, Werth is 7 for 22 with a double, a homer and three walks when he’s used as a DH.
