Mavs trade for Rudy Fernandez

DALLAS -- The Mavericks traded the Nos. 26 and 57 overall picks in the NBA draft to Portland for Rudy Fernandez and Petteri Kopenen, sources told ESPN.com's Marc Stein.

Fernandez is a three-year veteran shooting guard who has a career average of 9.1 points per game. Dallas president of basketball operations Donnie Nelson declined to reveal names until the trade became official, but he said the Mavericks acquired a player who could "potentially" start for them.

"The balance is a player that's a young one versus one that's been around the league for a few years and can help us win right away," Nelson said of dealing the rights to first-round pick Jordan Hamilton of Texas to Portland for a veteran. "Obviously, we're in a championship push mode."

Portland packaged the rights to Hamilton with point guard Andre Miller in a trade with the Denver Nuggets for point guard Raymond Felton.

The Mavericks have a vacancy at shooting guard with DeShawn Stevenson entering free agency. The 6-foot-6, 185-pound Fernandez could compete with Rodrigue Beaubois and Corey Brewer to be Jason Kidd's starting backcourt partner next season.

Koponen is a 6-foot-4 Finnish point guard selected by the Trail Blazers with the last pick of the first round of the 2007 draft. He has played the last three seasons for Italian powerhouse Virtus Bologna, averaging 12.1 points, 2.6 rebounds and 2.1 assists per game after recovering from a foot injury this season.

"This was our A scenario," Nelson said of the deal.
