PHOENIX -- The D-backs have reached an agreement with Bob Melvin on a contract extension through the 2010 season, a source with knowledge of the negotiations told MLB.com.
An announcement is expected within the next few days.
Melvin led the D-backs to a National League-best 90-72 record this past season, his third season at the helm. The D-backs were swept by the Rockies in the NL Championship Series. For his efforts, Melvin was named Manager of the Year by both The Sporting News and the Baseball Writers Association of America.
Not longer after the playoffs ended, general manager Josh Byrnes told Melvin the team would pick up his option for the 2009 season, and the two had preliminary talks on adding an additional year. Those talks went well, and the outline of a deal was quickly settled on.
It took a while, though, to get a final agreement, simply because Byrnes was tied up with a variety of other offseason projects and trade talks. Just prior to finishing up a blockbuster trade for Dan Haren this week, Byrnes and Melvin's agent, Casey Close, ironed out the final details.
Melvin was originally hired in November 2005 by then-GM Joe Garagiola Jr., but he and Byrnes developed an excellent working relationship when Byrnes took over following that season.
"This is where I want to be long term," Melvin said earlier this year about his future. "Josh has been unbelievable for me, very supportive. He's put together an outstanding baseball operations staff. Everyone, from ownership on down through the clubhouse, we're all on the same page. It's great to be a part of something like that. The future is only going to get better."
