Volkswacht Bodensee - Djokovic closing in on 100th title after Dimitrov downed in Miami

Djokovic, who now has a 13-1 record against the Bulgarian, totally dominated the contest which was over in 69 minutes.

The Serb -- who at 37 is now the oldest man to reach an ATP Masters 1000 final -- will face the winner of Friday's other semi-final between Czech teenager Jakub Mensik and American third-seed Taylor Fritz.

The match between Djokovic and his 33-year-old opponent was the oldest semi-final in Masters 1000 history, with a combined age of 70.

Djokovic was broken on his first service game but that was the extent of his difficulties as he maintained his record of never losing in a Miami semi-final.

The serve was once again Djokovic's strong suit -- he made 87% of his first serves and hit five aces -- but his all-round game was impressive and he will head into Sunday's final confident of becoming only the third man after Jimmy Connors (109) and Roger Federer (103) to win 100 titles.

"It was very windy today, very difficult to control the ball, changing direction all the time but I had good serves and held my nerves," Djokovic said.

"The serve was again the highlight of the match for me. I think it was 84% last game and I thought that would be difficult to beat that but today it was 87% so I don't know what to say?

"Hopefully I can continue in the same fashion because that definitely make my life easier," he said.

After a slow start to the season, Djokovic has his swagger back and his eye on his 100th win.

"After the Olympics, which was the 99th title, every tournament I play in has been going for 100 and I haven't be able to achieve that. Hopefully Sunday, I am going to go all in," he said.

Dimitrov has now lost ten straight mathches against the Serb and was philosophical in defeat.

"He's just doing the basics extremely well, better than anyone. You just cannot let yourself take a step down or make an easy error," he said.

Lionel Messi was in the stands to watch the game after training nearby with Inter Miami and Djokovic was delighted to see him.

"It was a huge honour to have King Leo in the stands, it was the first time I have played in front of him," he said.
