Stunning silver for Samuel

England's Laura Samuel shattered her personal best to win a shock silver medal in the triple jump at the Commonwealth Games on Tuesday evening.

The 23-year-old, who was unknown to all bar hardened athletics fans going into Glasgow 2014, launched herself out to 14.09 metres at a chilly Hampden Park.

The distance was 34 centimetres greater than her previous best and more than half a metre further than she had jumped this year.

It also sent the Leicester athlete up to third on the British all-time list.

Samuel, who finished 12 centimetres behind Jamaica's Kimberly Williams, has never competed before at a major senior championships.

She won world junior silver in 2010, but has struggled since with injuries.

Her distance would not make an impact on the world stage, but the extent of her progression is exciting.

After all, the day after the opening ceremony at London 2012 two years ago, she failed to win at a UK Women's League meeting in Swansea, while on the day of the closing ceremony she competed, and won this time, at a McCain Jumps and Throws Fest in Birmingham.

Samuel went out beyond 14m with her second attempt and, following three no jumps, recorded 13.98 with her final effort, which itself would have been good enough for bronze.

In the 10,000m Scotland's Beth Potter put up a brave challenge before Kenyan class told and Joyce Chepkirui led home a one-two-three in 32 minutes 09.35 seconds

Potter was then involved in a titanic domestic duel with England's Kate Avery for fourth, but, as both athletes were roared on down the home straight by the capacity crowd, the Scot was overhauled in the final metres and beaten by one hundredth of a second.

England's Martyn Rooney looked in superb form as he won his 400m semi-final in 45.22secs and he would have gone under 45 seconds had he not eased up considerably at the finish.

Rooney told BBC Sport: "I was happy with that, I felt confident and it showed."

Michael Johnson, the world record holder, added: "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."

Olympic champion and world number one Kirani James of Grenada showed his class in winning without breaking sweat in 45.14, but Rooney's England team-mates Michael Bingham and Nigel Levine both went out.
