Sportsmail's KIERAN GILL brings you the inside stories from Wimbledon ahead of the second Wednesday at this year's Championships.

KYRGIOS THE FASTEST GUN

Nick Kyrgios seems set to finish with the fastest serve of Wimbledon. His 143mph ace against Rafael Nadal — on a second serve — tops the table.

Of the men left in the quarter-finals, Sam Querrey has come closest to Kyrgios with 136mph.

The others' fastest serves have been: David Goffin (129), Roger Federer (127), Nadal (126), Novak Djokovic, Guido Pella (both 125), Kei Nishikori (123) then Roberto Bautista Agut (121).

COCO: FOLKS, IT'S A DREAM

Those waking up in America got to see Coco Gauff appear on NBC News's Today morning show at 7.40am on Tuesday.

Gauff is still in London, so she appeared via video link from Wimbledon.

'I'm still living a dream,' said the 15-year-old. 'Walking on the street, people were asking for pictures. That's just really crazy, and I don't think I'll ever believe it.'

Coco Gauff has become a global superstar after an impressive Wimbledon debut aged just 15

BRIT DUO TAKE ROUTE 13

The All England Club does not have a Court 13 — owing to players' superstitions — but Aorangi Park does.

It didn't bother Evan Hoyt and Eden Silva. Britain's wildcard pair practised on 13 then won a mixed doubles match against Joran Vliegen and Zheng Saisai 5-7, 7-6, 6-4.

Alison Riske warmed up on Court 14 ahead of facing Serena Williams, Roger Federer and Andy Murray opted for 15, while Rafael Nadal took 16.

KEI'S GOT A CHILL

Kei Nishikori faces eight-time Wimbledon champion Roger Federer on Wednesday and word in SW19 is that the Japanese No 8 seed is suffering from a cold.

Not ideal when you're about to face possibly the greatest player of all time on a surface he adores.

Kei Nishikori is said to be struggling with a cold ahead of his match against Roger Federer

SERENA STILL TOPS POLL

Wimbledon held a social media poll asking users which quarter-final they most looked forward to watching and more than 2,500 people voted.

Serena Williams versus Alison Riske attracted 44 per cent, Jo Konta against Barbora Strycova 30, while Simona Halep and Shuai Zhang got 19.

For Elina Svitolina and Karolina Muchova it was just seven.

BARTY'S CRICKET DETOUR

Ashleigh Barty was spotted at Euston Station on Tuesday flicking through crossword magazines and checking out the best-selling novels, including The Tattooist of Auschwitz.

Our Australian colleagues at SW19 suspect the world No 1 (and former cricketer) will get over her Wimbledon defeat by attending the Cricket World Cup semi-final between Australia and England at Edgbaston.

Ashleigh Barty exited the women's singles on Monday when she lost 3-6, 6-2, 6-3 to Riske

WORLD CUP STARS' DAY OUT

Members of the England team who reached the semi-finals of the women's football World Cup were at Wimbledon on Tuesday.

Neville was joined by Jill Scott, Demi Stokes, Toni Duggan, Karen Carney, Leah Williamson and Lucy Staniforth.

Golfing great Jack Nicklaus was there again too, having been in the Royal Box on Monday.
