"Whatever comes I will just take it", said Pliskova. "It's just lucky that I always won both of them".
She gained a second-set edge with a backhand victor on break point for a 4-2 lead before closing it out in just under 80 minutes. However, as it had all match, the forehand let her down as the Romanian sent it into the net. "I know I won, but I'm sure she feels like it was a great match as well, because it was a tough battle and very hot out there".
The results (finals): Men: Grigor Dimitrov bt Nick Kyrgios 6-3, 7-5. "I know that she has a lot of confidence coming with title from Wimbledon, so she's favorite, in my opinion", Halep said. "I was able to get some points and get back in the match but then I played a bad game". "I had match points against me so it was really hard".
"I think she played very solid, not missing much and obviously serving well".
Kyrgios' defeat - after excellent wins over incoming world No 1 Rafael Nadal, David Ferreror and Ivo Karlovic - leaves Lleyton Hewitt, who downed Gustavo Kuerten in Indian Wells in 2003, as Australia's most recent Masters champion.
Kyrgios, who matched his best ATP Masters runs from Miami the past two years, seeks his fourth career title after 2016 trophies at Marseille, Atlanta and Tokyo.
The battle for the No1 ranking in women's tennis has been raging for nearly a year, since Serena Williams passed on the baton after 186 consecutive weeks at the top to US Open champion Angelique Kerber. The year's last Grand Slam starts August 28.
The Wimbledon champion will meet the victor of the later semi-final between Simona Halep and Sloane Stephens.
The Wimbledon champion, seeded four, claimed her second title of the season with surprising ease, as she swept aside the Romanian 6-1 6-0 in Cincinnati.
Muguruza played and won her first final in the United States and becomes the first Spanish women to claim the title at the Midwest venue. "I got dominated. I can't control anymore the points". "I'm ready to get dinner and get in bed because I'm so exhausted".
"When I feel on court that I got dominated a little bit - I felt that I can not control the points - and that's maybe why I got a little bit down in my confidence", Halep said. I could move well. "I feel like if you're in the wrong place at the wrong time, it can happen anywhere". "It's back. So I'm positive again". In three tournaments since, the Spaniard has at least reached the quarterfinals. "Even if I would be second coming to the US Open, it's still better than I was past year".
Before Sunday's match, Dimitrov had a ATP World Tour 500 title and five ATP World Tour 250 titles, while Kyrgios countered with one and two, respectively.
