Novak Djokovic through to the quarters after defeating Quentin Halys 7-6 (3), 7-6 (5)

In the Australian Open warm-up event in Adelaide, Novak Djokovic rallied from 5-2 down in the opening set to defeat the determined Quentin Halys, 7-6 (3), 7-6 (5), and advance to the quarterfinals.

In his remarkable career, Djokovic has reached 211 ATP quarterfinals.

It appeared to be a mismatch on paper because Djokovic, who is ranked No. 5 to No. 64, had previously defeated him only once in straight sets, in the 2016 second round of the Australian Open, winning 6-1, 6-2, 7-6 (3).

All of that was quickly thrown out the window as Halys, who was playing extremely aggressively, dominated Djokovic with big first serves, strong groundstrokes, and a delicate touch at the net, breaking him early in the second game and finally gaining the previously noted 5-2 advantage.

Djokovic suddenly found his game at that time, however he quickly recovered, scoring 12 of the next 14 games to tie the match at 5-all and subsequently win the set in a tie-break.

With his win over Halys, Djokovic extended a couple streaks. He is now 31 matches unbeaten in Australia, with his most recent defeat coming to South Korea's Chung Hyeon at the Australian Open in 2018. He is also 19 matches unbeaten against Frenchmen since losing to Benoit Paire in Miami in 2018.

The 21-time Grand Slam winner has now triumphed in 20 of his past 21 matches on the professional tour, in addition to 28 of his most recent 30, and 37 of his most recent 40.

Denis Shapovalov, the No. 7 seed, will face No. 1 seed Novak Djokovic in the quarterfinals after defeating Roman Safiullin 6-4, 6-3 earlier in the day.
