Jordan Zimmermann told the Nationals this spring that he would not discuss a potential contract extension during the season.

Zimmermann will be eligible for free agency after the 2015 season.

"We talked a little bit in spring training," Zimmermann said. "My agent and I said once the season starts, we're going to wait until after the season. Hopefully, we'll maybe spring something up at the end of the season or going into next season or something.

"I'd be interested, see what they have to say. At the end of the day, it's got to be the right deal for me. I'm not just going to take a deal that's team friendly. It's got to be fair."
