Coach Scott Brooks repeatedly warned that winning every game during the Thunder's current six-game homestand would be no easy feat.
It only took just two games for him to be proven correct. The only thing more shocking than the Thunder losing was who the loss came against.
The Toronto Raptors, with the fifth-worst record in the NBA, completed their stunning two-game season sweep over OKC with a 95-93 victory Sunday night before a sellout crowd of 18,203 inside Oklahoma City Arena.
"Tough loss tonight," Brooks said, shaking his head after his team lost for just the second time in its last 11 starts.
The Thunder (45-24) came in riding a season-high six-game winning streak while the Raptors (20-49) were on a 14-game road losing streak.
Toronto routed the Thunder at home 111-99 on Dec. 3 and had gone just 11-38 between games against the Thunder. Ten percent of the Raptors' victories this season have been compliments of OKC, and the teams only played twice.
The Thunder also drops to 4-9 on Sundays this season.
The game had 17 lead changes and eight ties, but neither team shot well. Toronto misfired at 43.2 percent and OKC at 40.0 percent.
Raptors reserve guard Leandro Barbosa tied the game at 93 on a wide-open 3-pointer with 38.5 seconds left.
Barbosa taking a 3-pointer seemed like the obvious game plan. He finished with 19 points in just 14 minutes off the bench, shooting 7 for 10 from the field and 3 for 5 from 3-point range.
"When you're up three, the last thing you want to do is give them a wide-open look," Brooks said. "That was a great-executed play on their part. We didn't do a good enough job covering that."
Amir Johnson hit a 5-foot baby hook over Kevin Durant with 1.4 seconds left for the game-winner.
Durant's potential game-tying 20-footer from the left wing was an air ball that was long and was the end to a miserable shooting night for the All-Star, who went 6 for 21 from the field after going 30 for 55 in his previous three games.
