"The Nationals have agreed to terms with right-hander Chien-Ming Wang, a baseball source has confirmed to MLB.com. The terms of the agreement were not disclosed.

The Nationals are scheduled to hold a news conference Friday at Space Coast Stadium in Viera, Fla.

The United Daily News, a Taiwanese newspaper, was the first to break the news. The Nationals have not confirmed that Wang has signed with the team.

According to the newspaper, Nationals president Stan Kasten visited Taiwan's deputy ambassador, Daton Chang, last Friday and confirmed that Wang was going to sign with Washington and that the team would make an announcement Tuesday.

When reached by phone, Kasten declined to talk about Wang. General manager Mike Rizzo was not available for comment because he is in Tampa dealing with right-hander Brian Bruney's arbitration case.

The past two seasons, Wang has pitched in a combined 27 games. In 2008, Wang didn't pitch after the All-Star break because of foot problems. This past season, Wang had arthroscopic surgery on his right shoulder and missed the Yankees' World Series run in October.

At his best, Wang showed that he can be the ace of a pitching staff. In 2006 and '07, Wang went a combined 38-13 with a 3.67 ERA for the Yankees"

So it looks like the Wanger will be in the NL East this summer....hmm, sounds like a very, very strong fantasy sleeper if he comes back healthy.
