Minnesota has not lost a home game since a 107-95 setback to Utah on January 4. That loss dropped the Timberwolves to 17-15, but they have won 17 of their last 23 since.
The Wolves’ other 12-game home winning streak occurred over two seasons, from March 20, 1998 to February 22, 1999.
Minnesota has won six of its last seven games, including Wednesday’s 85-77 victory at Denver. Kevin Garnett and Wally Szczerbiak combined for 49 points in the win, which moved the Wolves a season-high 13 games over .500 for the second time this season.
Garnett collected 25 points and 14 rebounds for his league-leading 44th double-double of the season. Szcerbiak finished with a season-high 24 points on 9-of-20 from the field.
Detroit leads the league in scoring defense at 85.4 points per game and is on track to lead the league in that category for the first time since 1991-92.
The Pistons have won nine of 10 games and have taken a one-game lead over Indiana in the Central Division and a one-game edge over New Jersey for first place in the Eastern Conference.
Detroit has allowed an average of 79.7 points per game over the 10-game stretch and is coming of an 89-84 win at Toronto on Wednesday. Former Timberwolve guard Chauncey Billups finished with 18 points and hit a jumper and a 3-pointer in the final 98 seconds.
Billups, who signed a six-year $33.7 million contract in July, scored 21 points in the Pistons’ 106-82 rout of Minnesota on December 28. A win Friday would give Detroit its first series sweep of the Timberwolves since 1996-97.
