"The Washington Nationals are moving toward a 5-year, $45 million extension with third baseman Ryan Zimmerman, a source said. The deal is not yet finalized, but indications are that the contract could be announced within the next few days. A long-term deal with Zimmerman would culminate almost three years of negotiations and satisfy the team's longstanding desire to keep their 2005 first-round pick in Washington.
The deal would begin this year, wiping out the current one-year, $3.325 million contract Zimmerman signed with the Nationals in February. It would continue through 2013."
