MONTREAL (AFP) - Andy Murray will replace Roger Federer as number two in the world after defeating Japan's Kei Nishikori 6-3, 6-0 on Saturday to reach the final of the Montreal Masters.

The Scot will on Monday move into second on the ATP Tour's ranking list behind longtime number one Novak Djokovic, his Sunday finals opponent on the Canadian hard courts.

Djokovic defeated France's Jeremy Chardy 6-4, 6-4 in the other semi-final.

"It's nice to get back, especially after everything I went through last year with the (hip) surgery and dropping out of the top 10," Murray said.

"A lot of questions were being asked about how my game was physically.

"It's good to get back close to the top. I'll keep working hard and try to get that one spot higher."

Djokovic said he was annoyed during his match against Chardy by the smell of marijuana smoke coming from the stands.

"You can't believe how bad it was. I think it stopped after a while. Whoever it was... he was probably on the seventh sky somewhere," said the Serb.
