Jenkins saw off the likes of Simon Preston and Justin Smith while Koltsov also had a tough route through seeing off Colin Osbourne and Jesus Noguera who won last time out on the Challenge Tour but his charge was halted by the experienced Hampshire ace.
He adds to the nine-dart finish he also hit this weekend which in the process broke the record for the amount of perfect legs that have been hit in a year.
The other winners this weekend were Cody Harris, Nick Fullwell and Berry van Peer in another weekend that didn't really see one player really dominate proceedings.
