ESPN's Tim Kurkjian reported on Friday morning that Zimmerman was close to a contract extension with the Nationals, but Zimmerman denied the report when asked.
Asked if he felt he would get a deal done by Saturday morning, Zimmerman said, "There are still things that need to be worked on both sides. We need to do some stuff, they need to do some stuff. We'll see. ... I think we have come a long way from back where we started, so you never know."
Zimmerman's agent, Brodie Van Wagenen, was seen talking to Rizzo at the Nationals' Spring Training complex on Wednesday. The two sides also met on Thursday afternoon without coming close to a deal. The two sides were expected to talk on the phone Friday afternoon.
"I'm the same, like I was before," said Zimmerman, who was asked on Friday morning if he was close to an extension.
Van Wagenen left Viera on Thursday night. However, there is still a 24-hour window to get a deal completed. If not, look for Zimmerman to play out the rest of his current contract.
Zimmerman is coming off an injury-plagued 2011 season in which he hit .289 with 12 home runs and 49 RBIs across 101 games. He missed significant time because of an abdominal injury.
"The big things have to be taken care of -- the money, that kind of stuff, the big part of the contract," Zimmerman said. "There are obviously little things and language that take a little bit longer to be taken care of. But if we can get most of the big things done by Saturday, I don't have to sign the contract by Saturday. We have to have the pressing issues [finalized]. That needs to be done by Saturday.
"The point of me signing this deal is to be here, not to sign a deal that is team-friendly, to have it with another team. That's the whole point of the deal."
Manager Davey Johnson jokingly said he would postpone workouts on Saturday in order to get Zimmerman's deal finalized.
"He is the franchise player. He is the best player. He is the three-hole hitter. He is the leader of the infield. He is all of the above," Johnson said. "I think he wants to stay here. I think everybody wants him to stay here."
