Mike Rizzo doesn't believe the Washington Nationals have any serious needs as the trade deadline approaches.

"We don't have any immediate needs," the general manager said.

"I think the bench is solid. I can't see what upgrade we would get on the bench that’s on the market. It's balanced, it's productive, they're great guys, and they're versatile defensively. They're good, veteran players. All of them have been everyday players in the big leagues in the not-so-distant past," Rizzo added. "So it's a good bench."

The Nationals have a six-game lead over the New Yorks Mets and Miami Marlins in the NL East.
