The Nationals have engaged in preliminary conversations with Jordan Zimmermann's agent regarding a contract extension, according to a source. The conversations have not reached the right-hander, but he is open to a long-term contract. "I haven't talked to the Nationals about it," Zimmermann said. "I'd be interested. I'll just play it out and see what happens. I'm just going to go out and pitch the way I can pitch. Everything will take care of itself."
