What a day for Australian tennis!
So the US Open quarter-finals await for both Nick Kyrgios and Ajla Tomljanovic after two mighty impressive fourth-round victories.
Not too many players blast Daniil Medvedev off the court, but that's exactly what Kyrgios did today with a display of power and precision that few in the world are capable of matching. He is riding high and charging into the last eight with dangerous confidence.
As for Tomljanovic, her win was built off steely resolve and a determination to give nothing away easily. After a hectic week in the spotlight, she could easily have wilted under early pressure but instead stood up, faced the challenge head on and fought her way on top.
Thanks for joining me, Andrew McGarry and Jessica Riga on the blog today, I'm sure we'll be back again soon as this US Open heats up. See you then!

Unforced errors
Ajla Tomljanovic tallied up 27 unforced errors out there, which looks pretty good when you consider Liudmila Samsonova racked up 56(!) of her own.
That's where the match was won and lost. It was a sloppy affair at times, but Tomljanovic was the more composed and handled the crunch moments better.

Game, set, match! Ajla Tomljanovic is through to the QFs!
The Aussie charge in New York rolls on! That's a hell of an effort to back up from the win over Serena Williams, and Ajla Tomljanovic had to show incredible guts to fight through that dogged first set.
She saw off eight set points in the first to Liudmila Samsonova, a 20-minute game late in that set and a crunch tiebreak duel to set the match up, and then stepped into the second set with confidence and authority. Samsonova looked tired and broken after that first set, and Tomljanovic took full advantage.
She'll have to up her game again in the quarter-finals, but right now Ajla Tomljanovic is meeting every challenge head on.

What a win for Nick Kyrgios
The crowd is going OFF as Kyrgios hits signed tennis balls in to the crowd.
Everyone is excited by all that. Kyrgios hit a shedload of winners (53), broke the world number one FIVE times, and had a first serve percentage of 71.
Aside from a brain fade in the second set, he was the man in charge for much of this match and he thoroughly deserved the victory.
If he gets through against Khachanov, he will face either Matteo Berrettini or Casper Ruud for a place in the final. Anything can happen, and Kyrgios could well have a big meltdown that ruins his chances - but that is a very doable route to a second straight major final.
By Dean Bilton
Second set (1-0 Tomljanovic): Samsonova 0 - Tomljanovic 2*
Ajla Tomljanovic is in a fantastic position now, and is playing the better tennis. A big hold here and she is well on her way.

Samsonova is rattled now, that was an erratic swipe at a forehand. 30-0.
40-0. Ajla moving as well as she has all match.
Tomljanovic holds to love! Only looks one winner right about now.

Nick Kyrgios speaks after his win
"I still can't believe the boneheaded play I made over here (coming round the net to hit a winner) - it's going to be on ScoreCenter. That's ok!
Daniil is the defending champion, but I played really well. Where better to do it. A packed house in New York, I'm extremely blessed.
Kyrgios thanks his team, and his girlfriend for helping him stay on track. But he says he doesn't want to "let them down".
"I'm just glad I'm able to show you in New York what I'm capable of ... it's taken me 27 years (to do it)!"

By Dean Bilton
Second set (1-0 Tomljanovic): Samsonova 0 - Tomljanovic 0*
A lengthy break between sets as both players try to recover from that slog of a first set. Samsonova looks to be struggling on a knee a little, and is definitely looking tired.

Game Tomljanovic. Comfortable hold, and she's looking powerful right now.

By Dean Bilton
Ajla Tomljanovic wins the first set 7-6 (10/8)!
What a gruelling battle this is proving to be. Not vintage tennis from either player, but a whole lot of guts. Tomljanovic saved eight set points in that set before cashing in in the tiebreak.
Both players look fatigued, errors are dictating the game, but the Aussie has her nose in front.
