Shetland schoolgirl Erraid Davies was one of the undisputed stars of today's action, stealing Commonwealth hearts with bronze in the women's 100m breaststroke.

Glasgow 2014 organisers had to lay on extra buses in an attempt to get spectators to the stadium on time.
There were 1,350,000 extra journeys by road and rail, with an estimated 780,000 today alone, Glasgow 2014 organisers said.
ScotRail has delivered the biggest timetable the operator has ever seen with Glasgow Central handling 280,000 passengers on Friday, compared with 110,000 on a usual Friday, rising to 288,000 on Saturday. A record 174,000 people passed through Edinburgh Waverley.
Brian Devlin, co-chairman of the Glasgow 2014 transport programme board, said: "This has been a massive weekend of sport and festival in Glasgow, the city's largest ever.
"Over the last two days Glasgow Central Station alone has had the equivalent of the entire population of Glasgow pass through it.
"Almost 700,000 people have visited the city over the weekend and 1.3 million journeys were made by road and rail through the week.
"An estimated 30,000 people took to the streets to cheer on the marathon athletes and Glasgow Green live site recorded a bumper 39,000 people over the course of the day.
"There were some delays with buses from the park and ride sites to some venues but we managed to commission more buses and people did get to where they wanted to be. Almost 40,000 spectators cheered on the Scotland vs England match at Ibrox.
"We want to thank everyone who waited patiently and in good spirits as Hampden had a slower than anticipated start. But once up and running queues moved quickly and around 30,000 spectators were in for the first race.
"We will have our resources in earlier tomorrow and we have strengthened our transport plan and resources by adding additional capacity.
"While we're now past the busiest days of the games I would continue to urge spectators and the residents, businesses and other visitors to Glasgow to continue to bear in mind the additional pressures on the transport networks during this exciting time. Queuing may still be experienced at popular venues, events and stations. Thank you Glasgow."
