Yumi Kajihara of Japan won a dramatic women's omnium event on day three of the World Track Cycling Championships in Germany.

The omnium is a multi-discipline event for female riders, comprising a scratch race, tempo race, elimination race and points race, which all happened on the same day.

In a dramatic opening discipline, the scratch race, there was a five rider crash which saw Mexican rider Lizbeth Salazar stretchered off the track.

Britain's Laura Kenny, a double world champion in the discipline required stitches to her right eye after the crash, but completed the event after passing a concussion check, placing 12th.

Defending world champion in the omnium Kirsten Wild was ruled to have caused the crash after initially finishing second in the scratch race and after being relegated in the discipline could only finish seventh in the overall competition.

The dramatic scratch race was won by Kajihara who went on to win the overall omnium competition, taking gold with a total of 121 points, with Letizia Paternoster of Italy claiming silver with 109 points and Daria Pikulik of Poland taking bronze with 100 points.

There were a total of five finals on day three of competition at the Berlin Velodrome and the first of these was the men's points race, raced over a 40km distance, equivalent to 160 laps of the track.

Corbin Strong of New Zealand took gold with 58 points after he was the only rider to gain two laps on the field.

The silver medal went to Sebastian Mora Vedri of Spain with 40 points while Roy Eefting of The Netherlands took bronze with 36 points.

Kenny De Ketele of Belgium was the first to cross the finish line but only placed seventh in the overall standings because he did not gain a lap on the field.

The points race standings are calculated by the results of 16 sprints throughout the race at ten lap intervals, with additional points awarded to riders who gain a lap on the field - a feat managed by all the top six in the final standings.

Medals were also handed out in the men's one kilometre time trial with gold going to Sam Ligtlee of The Netherlands with a winning time of 59.495sec.

The other two medals both went to French riders as Quentin Lafargue took silver and Michael D'Almeida took the bronze.

In the men's individual pursuit Filippo Gana of Italy took gold in a time of 4min 03.875sec beating Ashton Lambie of the United States into silver (4:08.048).

Gana's gold medal winning time was not as quick as his qualifying time earlier in the day when he set a new world record of 4:01.934.

The bronze medal race was won by Corentin Ermenault of France in a time of 4:09.921.

In the women's sprint, gold went to Emma Hinze of Germany who beat Anastasiia Voinova of Russia in straight rides.

Bronze went to Sze Wai Lee of Hong Kong who beat her opponent Kelsey Mitchell of Canada also in straight rides.

Tomorrow sees the penultimate day of competition with a further four titles up for grabs - women's 500m time trial, women's madison, women's individual pursuit and men's omnium.
