TORONTO -- In a game billed as a battle of two of the NBA's best backcourts, the Toronto Raptors prevailed, edging the Portland Trail Blazers 117-115 on Friday night at Air Canada Centre.

Portland's Damian Lillard and CJ McCollum entered the game averaging 46.1 points and Toronto's DeMar DeRozan and Kyle Lowry were averaging 44.9.

The Trail Blazers lost, but the Lillard-McCollum tandem won the backcourt matchup with a combined 74 points on 24-of-45 shooting from the field and Lilliard finished with 50.

DeRozan and Lowry responded with 66 points on 15-of-34 shooting from the floor.

"They're really good. (Lillard) had 50 points tonight. That's why they're in the position they are -- in the playoffs -- because of that backcourt," said Lowry, who finished with 28 points and six assists in the win. "It wasn't nothing personal at all. It was our team trying to win against their team."

DeRozan finished with a team-high 38 points as the Raptors stretched their franchise-best winning streak to 12 games. He set a franchise record in a game with 24 made free throws and finished one shy of the NBA record for consecutive free throws without a miss.

He had a shot at the record with less than a second remaining but missed his final free throw of the night.

"Kyle told me to miss. I'm blaming it on Kyle," DeRozan joked. "I didn't know (about the record). I had no clue.

"(Lowry) told me 0.9 seconds, if you miss, they're going to try to wind up and throw it. But happy we got the win."

Toronto (41-19) swept the season series with Portland (33-30).

Lillard had five assists in addition to his 50 points. It was his ninth game with 30 or more points this season.

McCollum added 24 points and five assists.

With less than three seconds remaining, Lillard drained a 3-pointer to pull the Trail Blazers within 116-115.

"I was on the bench to start the fourth and I was just a little bit frustrated because it seemed like we couldn't catch a break," Lillard said. "We had a couple turnovers and I told myself on the bench, 'When I get back in the game, I'm going after this game; I'm going to try and take over the game.'

That was just my mindset."

Friday marked the fourth time an opposing player scored 50 points at Air Canada Centre. Kevin Durant was the last to do so on March 21, 2014.

"This kid, how he does not make (the all-star team), and I know he doesn't like talking about it, but how he isn't an all-star in our league, shame on us," Raptors coach Dwane Casey said.

"That young man can score any which way he wants to. Talk about (Steph) Curry coming across half-court, shooting it, this young man can come across half-court and shoot it also.

"I'm happy for him, the way he's handled the situation because he can be a bitter young man, but he's going to be trouble for all of us for a long period of time."

Portland dropped back-to-back games for the first time since a three-game skid on Jan. 4-8.

"It was tough. You never want to lose games," McCollum said. "We competed, but at the end, we weren't able to come up with the win."

DeRozan concluded the third quarter by sinking his 20th and 21st free throws to give the Raptors a 90-77 lead through three quarters. DeRozan passed his career high for free throws made and attempted at that point.

Toronto led 58-52 at halftime paced by a combined 34 points from DeRozan and Lowry.

The story of the first half was the teams combining for 34 personal fouls. Portland's Mason Plumlee had four of those through two quarters.

Toronto pulled away midway through the second quarter as Cory Joseph laid it in off the glass to give the Raptors 45-39 lead with 6:23 remaining as part of an 8-0 run.

The Raptors led 31-30 after the first quarter on 17 points from DeRozan. The teams combined for 20 field goals and 19 fouls in the first quarter.
