Lithuanian teenager Ruta Meilutyte's shock gold last night saw her become the youngest winner of the Olympic 100m swimming breaststroke (female).
Aged just 15 years and 133 days, Ruta led from the start and beat the much fancied American Rebecca Soni by 0.08 seconds.
She had earlier set a new European record in the heats - a mark that beat her personal best by two seconds.
She then went on to record a faster time in the semis on Sunday to qualify fastest for the final ahead of world champion and Beijing silver medallist Soni.
Speaking after her amazing victory, Ruta said "I can't believe it -it's too much for me."
Ruta moved to Britain three years ago and attends the same Plymouth school as Great Britain diving star Tom Daley.
USA pair Misty May-Treanor and Kerri Walsh Jennings continued their dominance of Olympic beach vollyball with the duo increasing their most consecutive victories in the event to 16 (and counting) along with the most consecutive sets won in Olympic beach volleyball is 32 (and counting).
The pair won back to back golds in 2004 and 2008, and look a good bet to make it three in a row after Monday's convincing 21-14, 21-19 win against the Czech Republic's Marketa Slukova and Kristyna Kolocova.
Meanwhile in weightlifting, North Korea's Kim Un Guk made his way into the record books after equaling Shi Zhiyong from China's heaviest weightlifting 62 kg snatch (male) benchmark with a 153 kg lift to take gold.
He also set a new mark for the heaviest weightlifting 62 kg total (male) with a rise of 327 kg . The record total consisted of a 153 kg snatch and 174 kg clean and jerk.
