New Raptors centre Khem Birch of Montreal also played, notching seven points and six rebounds.
"It put some pep in my step a little bit. It definitely put some more energy into the game," Boucher said. "I just want people to realize we have guys from Montreal that are really talented. It was an exciting showcase just to show people what we have."
"They both probably wanted to put on a show tonight and they both did it," Toronto coach Nick Nurse said.
Darius Bazley added 16 points and eight rebounds for the Thunder, who have lost 13 of 14 since leading scorer Shai Gilgeous-Alexander was sidelined last month by a right foot injury.
