The Toronto Raptors beat the Milwaukee Bucks 118-112 in double overtime to take the third game of the Eastern Conference finals.

Kawhi Leonard top-scored with 36 points as the Raptors grabbed their first win in the conference finals and narrowed the Bucks' best-of-seven series lead to 2-1.

Leonard also grabbed nine rebounds, with five assists and two steals, while four of his team-mates also reached double-digits – Pascal Siakam scored 25, Norman Powell came off the bench for 19, Marc Gasol added 16 and Kyle Lowry had 11 points.

Lowry and Powell both fouled out in the fourth quarter, but the Raptors managed to hold out for the win after an impressive block from Siakam with less than a minute of second overtime denied the Bucks another tie.

George Hill led the scoring for the Bucks with 24 points, while Giannis Antetokounmpo scored 12 but fouled out with 4.24 remaining in the second overtime.

Game four of the series returns to the Scotiabank Arena on Tuesday night.
