The Thunder balanced its roster, added depth to the frontcourt and continued to stockpile draft picks with its acquisition of center Etan Thomas on Monday.

The Thunder picked up the rugged, physical Thomas from the Minnesota Timberwolves in exchange for guards Damien Wilkins and Chucky Atkins.

Even more, Oklahoma City received Minnesota’s 2010 second-round draft pick as well as a conditional 2010 second-rounder, giving the Thunder five total picks in next year’s draft (it already has its own first- and second-round picks as well as Phoenix’s unprotected first-round pick).

Thomas is a Tulsa native who starred at Booker T. Washington High, and the 6-10, 260-pound center is expected to bolster the froncourt of Jeff Green, Nenad Krstic and Nick Collison as well as add toughness and experience to the rotation.

“We’re excited to have the opportunity to add Etan to our roster,” Thunder General Manager Sam Presti said. “We feel like he’s going to bring competitiveness and a defensive presence to our frontcourt that we value.”

Thomas, a seven-year veteran, has been with four teams but has only played for one.

Thomas was drafted No. 12 overall by Dallas in 2000, but was traded to Washington that February having never played for the Mavericks. With the Wizards, Thomas went on to average 6.0 points, 4.9 rebounds and 1.1 blocks per game over seven seasons. Thomas missed the 2007-08 season after undergoing heart surgery. Thomas, who played in 26 games last season, averaged 3.1 points and 2.5 rebounds before a mid-January knee injury sidelined him for the remainder of the season. Thomas was traded to Minnesota shortly before last month’s NBA Draft.
