(REUTERS) - The Toronto Raptors made no moves as the NBA trade deadline approached and passed. The Memphis Grizzlies were busy.

It looked that way on Sunday.

The Raptors played like a team that has stayed together and defeated the Grizzlies 98-85 led by 21 points from guard DeMar DeRozan.

A combination of trades and injuries had the Grizzlies in full re-grouping mode.

"We really battled our tails off," Grizzlies coach David Joerger said.

"For having a group that's just coming together in the last 48 hours, to go 1-1 this weekend (including a win over the Minnesota Timberwolves on Friday), that's pretty good."

Guard Kyle Lowry added 18 points and seven assists for the Raptors (36-18), who had lost their previous two games.

"I thought the defence was in the game," Raptors coach Dwane Casey said.

Forward Zach Randolph scored 18 points and grabbed six rebounds for the Grizzlies (32-23), who had won their two previous games.

The Raptors took a 10-point lead after three quarters and increased that to 14 in the fourth quarter.

The Grizzlies trimmed the lead to five points late in the fourth. But Raptors reserve guard Cory Joseph hit a three-pointer with 1min 9sec to play to give Toronto a 10-point lead.

Joseph finished with 14 points.

"We played better defensively today," Joseph said.

"Everything was quicker. Quicker to the ball, 50-50 balls, rotations were better. We just tried to keep them out of the paint and make them take tough shots."

Centre Jonas Valanciunas added 10 points and grabbed 12 rebounds for the Raptors, while reserve forward Patrick Patterson had 11 points with eight rebounds.

Reserve guard Mario Chalmers added 17 points for Memphis and guards Lance Stephenson, who was playing his first game for the Grizzlies, and Vince Carter scored 16 points each.

The Grizzlies hit just 36.8 per cent (28-for-76) from the field and were 15 per cent (3-for-20) in three-point attempts.

The Raptors shot 40.7 per cent from the floor (33-for-81) and 26 per cent (7-for-28) from 3-point range.
