Timberwolves sign Stiemsma

The Minnesota Timberwolves have signed center Greg Stiemsma to an undisclosed contract.

The 26-year-old free agent spent last season with the Boston Celtics and averaged 2.9 points with 3.2 rebounds and 1.55 blocks in 55 games.

"Greg had a fine rookie season for the Boston Celtics and is just beginning to mature as a player," said Timberwolves president of basketball operations David Kahn. "The physical nature of his game and his ability to rebound and block shots will be a welcome addition to our front court."

The 6-foot-11 Wisconsin product was previously signed by the Wolves in April 2010 and waived five months later. He played in Turkey in 2008-09 and 2010-11, while also playing in South Korea and in the NBA Development League in 2009-10.
