Shanghai Masters: Nadal grinds out tough win over Dmitrov

The second semifinals match will feature Roger Federer, who faces Juan Martin del Potro for the 23rd time in his career.

Sixteenth seed Del Potro heroically clambered off the floor from a set down to knock out Serbia's Viktor Troicki 4-6, 6-1, 6-4.

"I don't know how my wrist is after I fell down", del Potro said before leaving for a local hospital. "I felt something wrong in that moment, but I continued to play, just playing slices just to finish the match". I should hit that ball with the backhand, but I chose to go with the forehand before he hit the ball.

"Then I will take a decision for tomorrow".

"I'm a bit pissed off because I feel like I played well and that's the upsetting part of it - I could have done great in this tournament".

The next couple of games went past within a blink of an eye, and Harrison soon found himself serving for the set at 5-3 up.

Del Potro ended up breaking Troicki's serve in that fifth game and prevailed 4-6, 6-1, 6-4.

Earlier, Rafael Nadal tied Andre Agassi for sixth place on the all-time list of wins in the open era when he reached the semi-finals.

And he underlined his status as the man to beat in Shanghai as he battered the Italian Fognini 6-3, 6-1.

Dimitrov took Nadal into a decider at the China Open last week only to go off the boil when it mattered most to lose the game. In Beijing, he defeated Dimitrov in a three-set semi-final.

Nadal is yet to drop serve in Shanghai.

The 16-times grand slam victor, who beat Dimitrov in three sets in the China Open semi-finals last week, fired 32 winners and won two crucial breaks to prevail in two and a half hours at the Qi Zhong Centre.

"I played a very good match, I don't know how many mistakes I made, but very few", said the 16-time Grand Slam victor and top seed in Shanghai. "Of course, being able to win the US Open, Beijing and being in the semi-finals here". "I think both of us, we played at a very high level of tennis".

Fourth seed Cilic has reached the last four without dropping a set and overcame Nadal's countryman Albert Ramos-Vinolas 6-3 6-4, although the Spaniard did managed to break Cilic's serve for the first time in the competition at 3-3 in the second set.
