UNDATED (AP) — The Dallas Mavericks and Portland Trail Blazers are heading home, and they're bringing home-court advantage with them.

The Mavs and San Antonio are tied at one game apiece in the NBA's Western Conference quarterfinals after Monta (MAHN'-tay) Ellis 21 points in a 113-92 blowout over the Spurs. Shawn Marion finished with 20 points and Devin Harris added 18 for the Mavericks, who had dropped 10 straight against the Spurs.

The Spurs had a whopping 22 turnovers resulting in 33 points for the Mavericks.

Dallas would be up two games to none if it didn't blow a 10-point lead in the final eight minutes of the series opener.

Game 3 is Saturday in Dallas.

Meanwhile, Portland's LaMarcus Aldridge followed his franchise playoff-record of 46 points in Game 1 by providing 43 points and eight rebounds in a 112-105 triumph at Houston. That gives the Blazers a 2-0 lead in the Western Conference quarterfinals.

Aldridge kept the Blazers afloat by hitting 18 of his 28 shots while the rest of the starters shot a combined 13-for-41. Damian Lillard finished with 18 points and 11 assists but was just 3 of 14 from the field.

Dwight Howard had team highs of 32 points and 14 rebounds for the Rockets.

Portland hosts Game 3 on Friday.

Also on Wednesday, the Heat never trailed after carrying a 29-19 into the second quarter of a 101-97 win over the Bobcats, giving Miami a 2-0 lead in the Eastern Conference quarterfinals. LeBron James scored 32 points on 11-of-17 shooting and finished with eight assists and six rebounds. Chris Bosh was 4-for-5 from 3-point range and 8 of 11 overall in adding 20 points.
