Bulgarian Grigor Dimitrov won his first Masters 1000 title by beating Australia’s Nick Kyrgios in straight sets in the Cincinnati Open final.

World number 11 Dimitrov, 26, broke once in each set to beat his 22-year-old opponent, ranked 23rd, 6-4 7-5.

Kyrgios, also attempting to win his first Masters 1000 title, hit 31 unforced errors as he was outplayed.

In the women’s final, Wimbledon champion Garbine Muguruza thrashed Romania’s Simona Halep 6-1 6-0.

Kyrgios was the youngest Cincinnati finalist since Novak Djokovic in 2009.

But he could not reproduce the brilliance he displayed in beating world number two Rafael Nadal in the quarter-finals.

And, with the second set poised at 5-5, the Australian hit his fourth double fault of the match on deuce, before sending a wild forehand over the baseline.

Dimitrov served out the final game to clinch the biggest win of his career as he prepares for the US Open, which starts on 28 August.

“In the big picture, it means a lot to me,” said Dimitrov, who went through the tournament without dropping a set. “I’m pretty confident after that. This is what I’ve been practising for.

“I’m going to enjoy it for a day or two but then it’s back to the routine and prepare for the US Open.”
