Jannik Sinner completes epic comeback, Barbora Krejcikova wins easy at Australian Open

Jannik Sinner outlasted Marton Fucsovics 4-6 4-6 6-1 6-2 6-0 to reach the Australian Open fourth round on Friday while Barbora Krejcikova made swift progress after organisers defended their schedule at the Grand Slam over the previous day’s late finish.

Former French Open winner Krejcikova, a quarter-finalist at Melbourne Park in 2022, went through with a 6-2 6-3 victory over Anhelina Kalinina to remain on course for a potential meeting with American third seed Jessica Pegula.

But the 21-year-old Sinner was made to work harder after making a poor start to his match as he dropped his serve twice and made 18 unforced errors to lose the opening set.

A neat passing shot at the net after powerful exchanges from the baseline helped Fucsovics break for a 2-1 lead in the second set and the world number 78 heaped more pressure on his opponent by going two sets up before Sinner switched gears.

Italian Sinner, the 15th seed who has reached the quarter-finals of all four Grand Slams but has never gone any further, dropped only three games en route to the next two sets playing superior tennis against a fading Fucsovics.

He went on to blank his opponent to draw huge cheers from the crowd on Margaret Court Arena, which had witnessed an epic comeback from Andy Murray only hours earlier.

The former world number one was not happy to end his match at 4.05 am on Friday, describing the late finish as a “joke” and “disrespectful.”

Tournament director Craig Tiley ruled out any immediate changes after Murray said tennis must aim to avoid late finishes having completed a remarkable 4-6 6-7(4) 7-6(5) 6-3 7-5 win over Thanasi Kokkinakis.

“At this point there’s no need to change the schedule,” Tiley, who has had to negotiate delays caused by heat and rain, told the ‘Today Show’ on Channel Nine. “We’ll always look at it, when we do the (tournament) debrief — like we do every year.

“But at this point, at what it is, we’ve got to fit those matches in the 14 days, so you don’t have many options.”

Americans Sebastian Korda, Frances Tiafoe and Mackenzie McDonald are all in action later in the day.

No U.S. men’s player has captured a Grand Slam title since Andy Roddick at the 2003 U.S. Open, but the country’s hopes have been rekindled with eight players in the third round.

Two all-American matches are also scheduled for Saturday, meaning that a total of six American men can advance — which would be the highest number to reach the last 16 at the Australian Open since 1995.
