The source said that both sides want to continue to work together. Wang has said that he feels loyal to the Nationals because they stuck with him for almost two years while he was recovering from shoulder problems.
The source said there was a possibility that Wang would not file for free agency, which he is eligible to do following the conclusion of the World Series. If Wang filed, it would only mean "it was the date to file." Nothing more than that. Wang said in September that money will not be an issue in terms of resigning with the Nationals.
Nationals general manager Mike Rizzo and Wang's agent Alan Nero were both unavailable for comment.
Wang went 4-3 with a 4.04 ERA in 11 starts in a season he wished had not ended so soon.
"As many outings I get, I feel my shoulder is stronger, the breaking ball is coming back," Wang said in September.
Nationals manager Davey Johnson made it clear in September that he wanted Wang back next season.
"There is no doubt about it," Johnson said. "If I'm here, he could have my salary."
Although he has accomplished a lot this year, Wang wants to be even better next year.
"I'll try to work on my breaking ball more and hopefully get better and better again," Wang said in September. "Every year, we have to deal with different conditions. I hope I can have a really good year, get all my good stuff and keep myself at the best condition. I want to do my best in the future."
