Oklahoma City, OK -- (Sports Network) - The Oklahoma City Thunder have fired head coach P.J. Carlesimo after just 13 games and a league-worst 1-12 record.

"This was a very difficult decision to make," said Thunder executive vice president and general manager Sam Presti. "It is one that I felt was necessary at this time. I am very appreciative of the hard work and effort that P.J. gave to this team and we wish him the best in his future endeavors."

Assistant coach Scott Brooks will take over on an interim basis.

The Thunder have lost 10 straight games, including Friday's 105-80 setback at home against New Orleans. Brooks' first game will be Saturday in the back end of a home-and-home set with the Hornets.

Carlesimo, who was in his second season with the team, guided the SuperSonics to a franchise-worst 20-62 record in 2007-08, the organization's final campaign in the Emerald City.

Carlesimo has compiled a 204-296 regular season mark during his time as an NBA coach. He guided Portland for three seasons (1994-97) and then Golden State from 1997 until he was replaced during the 1999-2000 campaign.

The club also fired assistant coach Paul Westhead.
