WATCH: Bobby Portis beats the buzzer with breakaway dunk

Trailing Toronto by 10 with 12 second to play in the first half, the Bulls appeared to be on their way to their sixth consecutive loss, but a pair of buckets from Bobby Portis cut the halftime deficit to six.

The Bulls rookie knocked down a jumper then beat the buzzer with a breakaway dunk after a defensive rebound.

WATCH:

Portis has eight points and six rebounds in 11 minutes off the bench while Derrick Rose and Doug McDermott each have 10 points.

DeMar DeRozan has a game-high 18 for the Raptors.
