PHOTOS: Gold medal winners on Day 10 of the London Games

Aliya Mustafina was delighted to finally get Russia a gold in gymnastics. Beth Tweddle was thrilled to finally have an Olympic medal of any colour.

Just 18 months after blowing out her knee and putting her chances for London in doubt, Mustafina won the title on uneven bars Monday. It gave the 2010 World champion a full set of medals, following her silver in the team competition and bronze in the all-around. Mustafina couldn't take her eyes off the scoreboard after the final results were posted, staring at it with pride.

Any medal was fine with Tweddle, the inspiration for Britain's gymnastics renaissance. She'd come achingly close in 2008, missing the bronze by a mere 0.025, and briefly considered retiring. But she stuck around, and had an entire country supporting her. When the final results flashed, showing her in third, the O2 Arena erupted in a roar as if she'd won the gold.

He Kexin of China won the silver medal.

Arthur Nabarrete Zanetti flexed his bulging biceps to upset 2008 champion Chen Yibing and become the first Brazilian to win an Olympic gymnastics gold medal with victory in the rings final on Monday.

The 22-year-old gymnast, the last competitor to mount the rings, edged out Chen by 0.1 of a point with a score of 15.900 to win the strongman event. Italy's Matteo Morandi won the bronze.

World and Olympic champion Chen had been expected to retain his crown and seemed to have the gold in his pocket after a strong performance and solid landing. But Nabarrete Zanetti produced an inspired display to snatch the title away from one of the greatest rings specialists.

Bulgaria's 39-year-old Jordan Jovtchev, a bronze medalist in 2000 and silver in 2004, bowed of his sixth and final Olympics by finishing seventh.

Italian Niccolo Campriani thrashed the field to win the men's 50 meter three position rifle shooting event at the London Games on Monday as American Matthew Emmons endured another Olympic nightmare.

Campriani finished with a total of 1278.5 ahead of Kim Jong-hyun of South Korea in second on 1272.5 and Emmons third on 1271.3.

The Italian puffed out his cheeks after he completed his 10th and final shot of the final before raising his hands into the air at the Royal Artillery Barracks.

It was the Italian's second medal of the Games after he won silver in the men's 10m air rifle.

He took an eight-point lead after qualifying where competitors shoot 40 times in a kneeling, prone and standing position.

Campriani never looked like losing his lead as he peppered the 10.4 millimeter highest scoring ring to demonstrate why he is world number one with an Olympic record score.

He could afford to close out with scores of 9.7 and then 9 out of a 10.9 maximum to win by six points.

The battle for silver proved far more exciting with Kim overtaking Emmons on the final shot after the American shot a woeful 7.6 with the Korean's 10.4 giving him second.

The last shot by Emmons was reminiscent of his disastrous finale at the Beijing Games where he shot a 4.4 when leading to lose out on a medal.

That followed his 2004 Athens Games meltdown where he hit a target in the adjoining lane when set to clinch gold.

Four times World champion Tom Slingsby won Olympic sailing men's Laser gold on Monday, banishing the demons of his failure in Beijing in 2008 and succeeding after 12 years of preparation.

The Australian raced calmly to victory in the medal race on the Nothe course, comfortably leaving his nearest rival Pavlos Kontides of Cyprus well behind.

Kontides took silver and the honor of winning his country's first ever medal at the Olympics after 25 years as an independent sporting nation.

Rasmus Myrgren fought off the Croation challenge of Tonci Stipanovic to win bronze and a second sailing medal for Sweden following their gold in the Star class on Sunday.

There were emotional scenes as Slingsby's parents from Australia celebrated their son's win watching from the heights of the Nothe hill overlooking the course.

China's Xu Lijia won gold in the women's Laser Radial race at the London Olympics on Monday, leading from the front in a four-nation head to head.

The world champion silver medalist and 2008 bronze medal holder overcame a penalty turn to win the three lap race comfortably.

"I give it my best for Weymouth, the whole world and also for my country China", Xu told the BBC.

Marit Bouwmeester of the Netherlands won silver and Belgium's Evi Van Acker bronze in a fast race on the Nothe course in front of thousands of spectators.

Ireland's Annalise Murphy lost the battle for a medal, finishing fourth. Only one point separated the first four ahead of the medal race.
