Maryland Coach Mark Turgeon has signed his fourth recruit for the 2012-13 basketball season, with 6-foot-8 power forward Charles Mitchell making his plans to play for the Terrapins official.

Mitchell had informed the Terps he intended to come to Maryland during last month’s ACC tournament, and Turgeon couldn’t hide his enthusiasm although he was precluding from speaking publicly about it then.

In a statement released Thursday, Turgeon called it “a great day” for Maryland basketball.

“His mom did a lot of things right while raising Charles to be a respectful kid and extremely hard worker,” Turgeon said. “He is going to be a great addition to our frontcourt. Charles is a wide-bodied post who plays hard, is an excellent rebounder and can score around the basket. Charles fits in perfectly with the rest of our 2012 class, as he has a tremendous upside and will have a significant impact on our basketball program.“

The 250-pound Mitchell, who is from Marietta, Ga., averaged 17 points and 12 rebounds at Wheeler High School.

He joins a recruiting class that includes 6-9 center Shaquille Cleare of Houston, 6-8 forward Jake Layman and 6-1 shooting guard Seth Allen of Fredericksburg.

Maryland fans can get an early peek at three of the incoming freshmen — Mitchell, Allen and Cleare — at the Capital Classic on April 21 at T.C. Williams High. All are on the U.S. team, along with potential Maryland recruits Same Cassell Jr. and Damonte Dodd of Queen Anne’s County.

Mitchell is listed by as the 12th best power forward in his class and ranks 92nd nationally in the Rivals 150. And currently has Maryland rated as the 13th-best recruiting class nationally.

Mitchell chose Maryland over Seton Hall, Cincinnati, Florida State, Tennessee and Florida.
