"For all the giddy excitement about the appearance of Usain Bolt in the sprint relay, in 400m favourite Kirani James Glasgow is witnessing a bona fide track superstar at the peak of his powers. World champion at 18, Olympic champion at 19, his status on his home island of Grenada is such that the main road heading south from the capital St George's is now called Kirani James Boulevard."

"That was impressive from Kirani James, although that's what we expect from him because he's the class of the field. At some point he has to develop power because he has great endurance. I wonder if he will ever do that, because he could become a world record holder if he does that. He has a long stride, but not that power at the moment. I know it sounds strange but I would like to see someone break my world record one day!"

It was fun to have Bert Le Clos with us at the pool again. He took quite a shine to Becky Adlington.

"Martyn looks like he can run quicker. His execution of this race was good - he got round his first 200m well then composed himself before a strong finish. The biggest change in him is I see his attitude. It's a lot more serious, focused and with belief in his talent to say 'I should be here' now."

England's Martyn Rooney looks pretty pleased after qualifying for the men's 400m final - but refuses to be complacent.

"I was happy with that, I felt confident and it showed," he tells BBC Sport. "I need to make sure I'm in contention on the home straight because I'll always be in with a shout if I'm in the mix at that stage. The time wasn't great but it was enough for today. I know I'll need more in the final."

Told you so. Kirani James almost has a cigar in his mouth as he jogs down the last 100m for a time of 45.14. Very impressive. South Africa's Wayde van Niekerk grabs the second automatic qualification spot, with England's Michael Bingham in fourth. No place for the 28-year-old in Wednesday's final.

Beth Tweddle:, external Amazing day at the gymnastics England men and women take gold, Scotland silver in the men's and Wales third in the women's.

New Zealand's Sophie Pascoe coasts to victory and only narrowly falls short of setting a new world record. Australia's Katherine Downie clinches silver, while there is a bronze for Canada thanks to Aurelie Rivard.

Semi-final number two. And there is one man who is expected to blow the rest out of the water - Olympic champion Kirani James of Grenada starts in lane four.

"All of the talent we saw back in 2006 from Martyn Rooney came out in that race, and we're seeing him back to something like his best now. He glided home in the end with an impressive run. He's up against Kirani James but he's shown he will be a contender. That was a top quality performance."

Silence in the Glasgow evening air is pierced by the starter's gun. England's Martyn Rooney, complete with a non-aerodynamic bushy beard, sits in the middle lane, pounding along nicely before hitting the straight hard. He steps down on the gas, looks left, looks right and wins the first semi-final in 45.22. Trinidad's Jarrin Solomon and Chris Brown of the Bahamas, who has more gold, silver and bronze than Mr T from the A-Team, trail in his wake.

"Does the swimming really have to end here in Glasgow?

"The crowd are loving it and the home nation athletes appear unstoppable at the moment. Even Wales have finally joined the party - their first women's gold in the pool for 40 years last night and now they have two in two days!

"Georgia Davies has her hands on that precious medal and she won't be letting it go for a while!"

Time for a recap from the Tollcross International Swimming Centre. Four races down, four to go. Wales have added one gold - thanks to Georgia Davies - and one silver - in the shape of Jazz Carlin - to their overall medal tally. Ben Proud has also secured England a ninth gold in the pool at the Games. Meanwhile, home fans have been celebrating Daniel Wallace's silver in the 200m individual medley.

"I'm really looking forward to the 400m tonight, both the men's semi-finals and the women's final. With the women, Novelene Williams-Mills is looking in good shape and Christine Day has been quick so it looks like Amantle Monthsho will have her work out to win it. All eyes will be on Kirani James in the men's semi-finals but of the English guys Martyn Rooney and Michael Bingham have a chance of making the final."

What is that you say? You want some 400m action. Coming right up....

England's John Lane is right in the bronze-medal mixer. He is fourth going into the final event - the 1500m - with Damian Warner of Canada leading the way.

Magical moment for England's Adam Gemili. The 20-year-old sprinter is beaming from ear to ear as he walks back out into Hampden Park to collect his silver medal from the men's 100m. Sure he will experience a few more of these ceremonies in the coming years...

Men's individual medley silver medallist Daniel Wallace of Scotland tells BBC Sport: "If you'd have told me before the Games I was going to get two silvers and one gold I'd have never believed you! I've got a few weeks off now for a break, and then it's back to the United States for training again."

The Welsh national anthem booms out at the Tollcross International Swimming Centre as Georgia Davies receives her 50m backstroke gold medal. Unlike team-mate Jazz Carlin 24 hours ago, there are no tears from the 23-year-old.

Another silver medal is snaffled by Team England as 23-year-old Laura Samuel sticks another 34cm on her personal best. Her effort of 14.09m is enough to finish 0.12m behind Jamaica's Kimberly Williams, who adds the Commonwealth title to the World Indoor bronze she won earlier this year.
