Nick Kyrgios is on a roll ahead of the US Open, surging into his first ATP World Tour Masters final in Cincinnati.

A day after knocking over Ivo Karlovic and world No.1 Rafael Nadal within hours, Kyrgios beat Spanish veteran David Ferrer 7-6 (7-3) 7-6 (7-4) in his semi-final.

The 22-year-old Australian will play Grigor Dimitrov for the title after the Bulgarian tamed the big serve of John Isner to win 7-6 (7-4) 7-6 (12-10) in Saturday’s earlier semi-final.

Tuning up for the US Open in just over week, world No.23 Kyrgios will be seeking his fourth and biggest tour title – the first at Masters 1000 level – following wins in Tokyo, Atlanta and Marseille last year.

Having struggled with hip and shoulder injuries in the past two months, he appears to be healthy, as evidenced by his twin wins on Saturday.

His only previous appearance in a Masters 1000 final came in Miami where he played a classic against Roger Federer before succumbing.

Kyrgios fired down 14 aces to Ferrer’s one but still needed a little over two hours to see off the speedy Spaniard.

Dimitrov beat Kyrgios in three sets in their only previous meeting at Indian Wells in 2015.
