It’s been hot and humid in New York, and the temperatures seem to be inflaming tempers and tensions at the US Open.

But while younger men were falling over, a well-hydrated Lleyton Hewitt went to the wall again.

• The good, the bad and the ugly: Round 1 
• McEnroe blasts ‘bonehead’ Kyrgios after loss

There was a also a bomb scare, and why’s a former champ being forced to catch the bus?

Read on…

The good

Just like he did at Wimbledon, Lleyton Hewitt bowed out of a grand slam in another five-setter.

Hewitt reminded us all of his fighting qualities, again, in an excellent match against compatriot Bernard Tomic.

Tomic served for the match when leading two sets to love but Hewitt clawed his way back into the contest with a typical dose of grit and hard work. And although Tomic eventually hung on in the fifth set, it was an excellent match full of highlights.

Andy Murray also dug deep, fighting back from two sets down to defeat Adrian Mannarino in five.

It was the seventh time he has produced the ultimate comeback at a grand slam – a most impressive feat.

Bethanie Mattek-Sands’ effort deserves praise, too, after she made the third round for the first time in 14 attempts at Flushing Meadows. Her opponent, fellow American CoCo Vandeweghe, also caught the eye – but more on that later.

In another round full of dummy spits and tantrums, world No.1 Novak Djokovic reminded us tennis can still be lots of fun with this post-match dance.

The bad

Samantha Stosur isn’t getting much help from US Open officials.

She was first denied a courtesy car for a trip to Flushing Meadows on her day off to practice, meaning she took the bus.

“When you are still in the tournament and you try and book a car and they say you can’t have one before 10 (o’clock) because you don’t have a match, I don’t think it’s good enough,” Stosur said.

“It’s not just me. There have been many players in that situation. It’s a grand slam. It’s one of the biggest tournaments in the world.

“You’ve got to be able to provide transport to players when they need it.”

And that wasn’t where Stosur’s issues ended.

She was also forced to practice on three different courts as the officials struggled to deal with the hundreds of players wanting to practice.

The end result?

Well, Stosur didn’t let it bother her, thrashing Russian Evgeniya Rodina 6-1 6-1 in 51 minutes.

Swiss teenager Belinda Bencic carried on right throughout her three-set win over Misaki Doi, arguing with officials and smashing her racquet.

And there was this attempted racquet bounce…that didn’t go to plan.

The ugly

There’s been no shortage of racquet smashing over the first four days but Vandeweghe’s effort really caught the eye. She obviously doesn’t do things by halves…

Something tells me Coco Vandeweghe wasn’t happy with how her game was going here… #USOpen https://t.co/6cxzSLyiUB

And there was also an unsavoury incident for Italian Flavia Pennetta, who feared a bomb had exploded during her second-round win over Monica Niculescu.

It was a drone – that crashed in an empty section of the stadium – and Pennetta admitted she was very scared.

“I feared the drone was a bomb,” Pennetta told www.tennisworlditalia.com.

“With all the news out there, I thought it was over. My team was so scared.”

The plain weird

While Nick Kyrgios’ bid to deal with the heat was to mimic taking a nap during on-court breaks, Caroline Wozniacki had an alternative, cooler method.
