ATLANTA -- The expectations for the Toronto Raptors are never very high when guard DeMar DeRozan scores only two points.

But on Saturday night, with DeRozan suffering through an off-night, the Raptors leaned heavily on their bench and they responded. Three reserves sparked Toronto to a big second quarter and helped the Raptors break a two-game losing streak with a 112-78 victory over the Atlanta Hawks on Saturday night at Philips Arena.

The trio of Norman Powell, Jakob Poeltl and Pascal Siakam, who have a total of five years in the league, combined for 44 points -- 28 in the second quarter when Toronto outscored Atlanta 39-14 to take a commanding lead it never relinquished.

"They're going to have nights when they don't look as good, but the young guys came out tonight, they were clicking, they were making plays, they were playing together, the spacing was good, the passing was good and the shooting was good," Toronto coach Dwane Casey said.

The Raptors (12-7) got 17 points from Powell, 14 from Poeltl and 13 from Siakam.

"Credit to Toronto," said Atlanta coach Mike Budenholzer. "In particular their bench was phenomenal in the first half. Impressive effort by them, their competitiveness, their toughness. Just wasn't a good night for us, but a lot of credit to Toronto for the way they played."

Powell, who missed four games earlier this month because of a right hip pointer, fell two points short of matching his season high. Poeltl equaled his career best.

"Tonight was about us, about coming out with the right sense of purpose, and disposition and togetherness," Casey said. "We've had two tough losses, but thought our guys responded well."

The Raptors placed seven players in double figures, including Kyle Lowry with 15 points and 13 rebounds. DeRozan scored only two points and fell one game short of matching the team record of 114 straight games in double figures. Lowry and DeRozan each played 27 minutes after playing 39 on Friday.

"We tried to buy them some minutes with both of them off the floor," Casey said.

Atlanta (4-16) was led by point guard Dennis Schroder with 14 points and four assists. Taurean Prince and Marco Belinelli each scored 10.

It was the fewest points scored by Atlanta this season. The Hawks had only 85 against San Antonio on Nov. 15.

Both teams played Friday night and each was a bit ragged in the first quarter.

It took nearly two minutes for the Raptors to score the game's first points and DeRozan didn't score until five seconds left in the quarter, which Toronto led 28-25.

The Raptors took over in the second quarter and blew the game open when they shot 68.2 percent compared with 22.2 percent for the Hawks. Toronto outscored Atlanta 21-3 to open the quarter.

Powell had 13 points and Siakam scored nine in the second quarter.

"They came out with more energy than we did," Atlanta forward Ersan Ilyasova said. "It's a tough night. You can't make an excuse, but down 20 in the first half, you have to come out with more energy and intensity. Give them credit. They shot the ball at a high percentage."

The 67-39 lead was the largest halftime advantage for Toronto this season and the biggest halftime deficit of the year for Atlanta.

"Our defense was just ... they were shooting 64 percent at the half," Budenholzer said. "They're driving it, kicking it, driving it again. I feel like our defense was not good enough for an NBA game tonight."

The Hawks came back from a 17-point deficit in the second quarter against New York on Friday but had any comeback hopes quickly thwarted in the third quarter when Toronto scored the first six points and upped its lead to 34 points. Atlanta didn't score until Prince made a 3-pointer with 8:41 left.

"We challenged them," Casey said. "Everybody in the world is talking about how bad we are in the third quarter and we take that as a personal challenge. Guys came out and responded."
