WASHINGTON -- Center Marcin Gortat scored 24 points and guard John Wall had 19 points and 15 assists as the Washington Wizards downed the Toronto Raptors 106-99 on Friday night for a commanding 3-0 lead in the best-of-seven playoff series.

Six Wizards scored in double figures, including forward Paul Pierce with 18 points on four 3-pointers.

Pierce and Otto Porter fueled a decisive 10-2 run late in the fourth quarter and both forwards sank two 3-point shots inside the final 4:23. Pierce's final bomb with 16.9 seconds left came after the Raptors pulled to 102-99.

One of two lower seeds to win on the road in the postseason, Washington claimed both Game 1 and 2 in Toronto. The Wizards have never led a series 3-0 in franchise history. They can close out the first-round series Sunday in Washington.

Toronto's DeMar DeRozan started 8 of 10 from the field and scored 20 of his 32 points in the first quarter. However, the shooting woes that plagued him and backcourt partner Kyle Lowry in Toronto returned. The Raptors shot 37.4 percent from the field.

With the teams tied at 88 with 4:23 left, Porter's 3-pointer put Washington up for good. His breakout series continued with another confident 3-pointer and Pierce added one from beyond the arc for a 98-90 lead with 1:58 remaining.

After Lowry's 3-pointer cut the lead to 102-99 with 40 seconds left, Pierce countered with his own. The longtime Boston Celtic joined the Wizards this offseason after spending last season with the Brooklyn Nets. He turned toward the crowd after the 3-pointer, raised his arms and screamed, "And that's why I'm here."

DeRozan and Lowry each missed 10 shots in a row during a long stretch. DeRozan finished 11 of 29 and Lowry went 5 of 22 for 15 points.

Forward Amir Johnson had 14 points and 12 rebounds for the Raptors.

The Wizards won despite committing 17 turnovers, eight more than the Raptors.

Gortat grabbed 13 rebounds. Guard Bradley Beal scored 16 points, forward Drew Gooden had 12 and Porter added 10 for Washington.

With Wall directing the pass-first attack, the Wizards had assists on each of their first 10 baskets. Wall is averaging 13.3 assists through three games.

The Wizards anticipated a strong push from the Raptors early. That happened, but the Wizards punched themselves off the ropes in the second quarter.

DeRozan's second 3-pointer of the first quarter gave the Raptors their largest lead at 28-18 and his third had Toronto up 35-26 with 1:56 left in the quarter.

The Raptors had 13 points in the second quarter as the Wizards went from trailing by 10 to a 54-48 halftime lead.

Gooden entered this season without a 3-pointer in the playoffs and made three in the first half.
