Cavendish and Bostock in the points
Manx cyclist Matthew Bostock topped the billing in the 40-lap Derny race on Day 4 at the Six Day London.
He beat compatriot Mark Cavendish's team-mate Owain Doull to first place.
The duo of Cavendish and Doull triumphed in the 20 minutes Madison Chase.
Day 5 was also a successful one for Doull and the Manx Missile as they won both the Team Elimination Race and the 30 minute Madison Chase.
It puts them top of the general classification heading into the final day on Sunday, with Bostock and his team-mate Andrew Tennant in 14th.
