Spanish world No. 1 Rafael Nadal's victory over Novak Djokovic in the semifinals of the Montreal Masters and his five-set defeat of the Serbian in the French Open semis were chosen by the ATP World Tour as the two best matches of 2013.

Nadal's 6-4, 3-6, 7-6 (7-2) win in Montreal was chosen as the best match at an ATP World Tour event, while his 6-4, 3-6, 6-1, 6-7 (3-7), 9-7 triumph at Roland Garros was considered the best match at one of the four Grand Slam events, which are governed by the International Tennis Federation.

The win in Montreal was part of Nadal's surprising 26-match winning streak on hard courts, the Spaniard's least favorite surface until this year.

Two months earlier, Nadal came from a service break down in the fifth set of the French Open semifinals to edge Djokovic, who has been mounting a stiff challenge to the Spaniard's clay-court dominance in recent years.

Nadal then routed countryman David Ferrer in the final to increase his record haul of French Open singles titles to eight.

The Spaniard also won the U.S. Open in September to cap off a stunning comeback after missing several months of 2012 with a knee injury.

Two contests involving Djokovic and Argentina's Juan Martin del Potro, meanwhile, were selected as runner-up in the Grand Slam and ATP World Tour best-match categories.

The Serbian won both of those battles, defeating Del Potro 7-5, 4-6, 7-6 (7-2), 6-7 (6-8), 6-3 in the semifinals of Wimbledon and 6-1, 3-6, 7-6 (7-3) in the Shanghai Masters final. EFE
