The 21-time Grand Slam champion saved two break points as Kyrgios continued to dominate on his serve. But it was soon Kyrgios’ turn to fight back on his serve, hitting three aces to save two break points.
Nadal was eventually able to find the breakthrough on his next opportunity though to take the break midway through the deciding set, but Kyrgios immediately launched into a tirade at chair umpire Carlos Bernardes about the noise from the crowd. Kyrgios ferociously shouted: “How long you gonna let that s*** go on for? How long?!
Bernardes was able to keep his cool in discussion with Kyrgios but the Aussie had it all to do after Nadal raced to a love-service game to take a 5-3 lead. Kyrgios ended up holding his serve to force Nadal into serve for the match, but the world No 4 was unrelenting and gave nothing away as he picked Kyrgios apart to advance to the semi-finals.
