Sussex-based Roundstone Racing maintained their championship aspirations at the British Superbike Championships at Mallory Park.

In the Superstock class, Roundstone duo John Crockford and Chris Burns finished first and second respectively last Sunday, leaving the championship wide open going into the final round of the series at Donington Park next weekend.

Championship leader David Jefferies was in third place when a massive high side saw his race come to an end, leaving him with two dislocated toes.

Jeffries has 221 points with Burns on 211 and Crockford on 203.

Tommy Hill, from Lingfield, finished tenth.

In the Junior Superstock Championship, Roundstone's third rider Craig Jones once again had a race long battle with his championship rival Tom Sykes.

This time it was Sykes who took the win with Jones finishing second but the Sussex team rider holds a five-point lead ahead of the final round.

Darren Jones has added the BEMSEE club's Rookie 600 nationwide title to his Southern series crown.

The Horsham rider completed his double at Lydden Hill in Kent last weekend, winning his first three races before being knocked off by another rider while leading the fourth race.

Jones, who gets support from AJS Limited and PJ Brown, said: "I'm absolutely delighted."

In the Rookie 400 class, Andrew Ballard from Portslade remains second in the nationwide championship despite a few problems at Lydden.

Ballard claimed two third places in Saturday's two races. In Sunday's first race he did not make it off the startline and that meant he had to start from the back of the grid for the last race, which saw him climb from 28th place to finish sixth.

Ballard's pal, John Evans, also from Portslade, claimed a fourth and a sixth on Saturday. In the first race on Sunday, he was knocked off and suffered a broken finger which is likely to rule him out for the rest of the season.

Evans had been challenging for third place in the series.

Peacehaven's Kevin Stone dropped from third to fourth in the same series despite two fourths on the Saturday, followed by a third and a fifth on Sunday.
