World number two Rafael Nadal has reached the final of the Mexican Open by beating Grigor Dimitrov. The 33-year-old Spaniard, who remains on course for his third Mexican title, cruised past the Bulgarian 6-3, 6-2 in the semi-final.

He will face 22-year-old Taylor Fritz, who had to come from behind against fellow American John Isner 2-6, 7-5, 6-3 in Acapulco. World number 35 Fritz beat Britain's Kyle Edmund in the last eight.

Britain's Heather Watson is one win away from her first WTA title in almost four years after beating China's Wang Xiyu to reach the final. Watson, 27, won 6-4, 7-6 against the 18-year-old in the semi-final. 

The British number two, who has not won a title since the Monterrey Open in March 2016, will play in her fifth tour-level final. She will face Canada's Leylah Fernandez after she beat Mexican wildcard Renata Zarazua.
