Harrie Lavreysen of The Netherlands won both sprint events to maintain his 100 per cent record at the International Cycling Union (UCI) Track Champions League in Berlin.

The second leg of the event also saw Ellesse Andrews of joining him, with two wins and a maximum 40 points.

Lily Williams of the United States got one over Katie Archibald of Britain in scratch, but the two-time Olympic gold medallist was back on track, winning her ninth elimination.

It also put Archibald, a five-time world champion, six points ahead of the America in the overall table.

Despite not winning, Japanese rider Eiya Hashimoto will defend the jersey after a fifth and second place finish in the scratch and elimination respectively.

Sprint world champion Lavreysen, who won the first round in Mallorca, was unstoppable in the keirin final, where he edged Australian Matthew Richardson.

The 13-time world champion gave no chance to Mateusz Rudyk of Poland in the sprint final as well.

"I felt really good today and really enjoyed my night. In the Sprint, the semi-final was almost tougher than the final - going up against Matthew [Richardson] and Mikhail [Yakovlev] - but winning that meant I was relaxed for the final," Lavreysen said.

"In that I went full gas, didn't make any mistakes, and it felt really good to beat Mateusz [Rudyk].

"That triumph also meant I had a lot of confidence going into the Keirin final.

"That was another hard race.

"There was a lot going on around me so I knew I needed to go really quickly to the finish line.

"I didn't think it would be possible to win both races again, so I'm delighted to have done it."

Andrews disappointed home favourite Alessa-Catriona Pröpster in the semi-finals with a dominant performance before repeating the feat against compatriot Katy Marchant in the final.

Pröpster was no table to keep up in the keirin final too, as the Kiwi established an insurmountable lead in the final lap.

Archibald meanwhile was stunned when Williams slipped away with a virtual lead befor ethe elimination.

But the seasoned Scottish star made up for it, downing Canadian Maggie Coles-Lyster for the win.
