TORONTO - Pascal Siakam had 23 points and 10 rebounds, Kawhi Leonard scored 22 points and the Toronto Raptors beat Miami 117-109 in overtime on Sunday, further denting the Heat's fading playoff hopes.
Norman Powell matched his season high with 23 points, Danny Green scored seven of his 21 points in overtime and OG Anunoby had 12 as Toronto won its fourth straight over the Heat.
Dwyane Wade scored 21 points and James Johnson had 18 for the Heat, who have lost a season-high four straight.
Miami could have guaranteed a postseason berth by winning its final three games -- the Heat host Philadelphia on Tuesday and close the regular season at Brooklyn the following day. Miami was in position to be eliminated later Sunday if Orlando defeated Boston and Brooklyn beat Indiana.
Dion Waiters scored 17 points, Justise Winslow had 15 and Hassan Whiteside 14.
With the score tied 103-103, Wade and Leonard each missed 3-pointers in the final 35 seconds of regulation. The Heat called timeout with 10 seconds left after grabbing Leonard's miss, but couldn't capitalize. James Johnson missed a potential winning jumper, and Bam Adebayo couldn't beat the buzzer with his layup.
Green opened the extra session with a 3, then added a layup to put Toronto up five, the biggest margin for either team since the start of the fourth quarter. The Raptors outscored the Heat 16-6 in overtime.
The crowd of 19,800 rose for a brief ovation when Wade checked in for the first time at 6:18 of the first. The 16-year veteran intends to retire at the end of the season.
Wade scored five points in the opening quarter and Miami led 26-25 after one.
Whiteside scored 10 points and the Heat made 10 of their first 12 shots in the second, opening a 49-36 lead. Toronto called its second timeout of the quarter before responding with a 10-0 run as Miami went scoreless for 4:17. Winslow stopped the drought with a 3 and the Heat led 57-50 at halftime.
Leonard scored eight points in the third as Toronto closed the gap, but Miami took a 79-78 lead into the fourth.
