The Queenslander cemented her rise into the top 10 rankings for the first time – the first Australian to do so since Samantha Stosur 2013 – with a 7-6 (7-1) 6-3 win over fifth-seeded Karolina Pliskova on Saturday.
The Australian No.1 was 3-1 down against 27-year-old Pliskova but responded with excellent shot-making to force a tiebreak and outclass the Czech world No.7 by winning six straight points for the first-set.
Barty broke the big-serving Pliskova in a 12-minute game to open the second set and from there on the fatigued Czech, whose semi-final win over Simona Halep finished after 1am local time earlier in the day due to rain delays, put up little resistance.
Barty pumped her fists when Pliskova sent a forehand long on match point to hand the 22-year-old her fourth WTA title and a $1.3 million ($A1.8m) winner’s cheque.
