Batley Bulldogs suffered a 32-8 defeat away to London Broncos as they slipped to third place in the Kingstone Press Championship table.
London hit the front when a penalty took them deep into Batley territory and after William Barthau and Elliot Kear linked, winger Rhys Williams dived over in the corner.
Barthau’s long looping pass sent Williams over for a second try soon after but Batley responded well to level.
Half-backs Dominic Brambani and Cain Southernwood combined to create a huge gap in the London defence, which full-back Dave Scott exploited to race through and score.
Pat Walker converted and was on hand to level matters at 8-8 with a penalty goal.
Batley had a chance to take the lead when Brambani kicked towards the corner but winger Alex Brown was unable to gather.
London then struck two telling blows in the lead up to half-time.
Barthau’s neat kick initially forced Batley to drop out and when the Bulldogs were penalised soon after it gave the Broncos a good attacking position.
Barthau and Kear linked again to send Ben Hellewell racing over for a try which scrum half Barthau improved.
London earned a 10 metre scrum when Alex Brown dropped a kick through.
James Cunningham took play towards the posts before London moved the ball out for Eddie Battye to power over.
Barthau added his second goal and London led 20-8 at half-time.
London also began well after the break and the impressive Barthau dummied his way over for the Broncos’ fifth try.
Batley’s hopes of producing a fightback were ended when Tom Lillycrop was sent off for a late tackle following a Barthau kick through.
The Broncos capitalised as Barthau and Jack Bussey linked with slick handling to send Kear charging through a gap and over for the try.
London made good use of the extra man advantage and added a seventh try after 67 minutes when Mark Ioane forced his way over from close to the Batley line.
Barthau was unable to improve any of his side’s second half tries but London had done enough to leapfrog the Bulldogs and move second in the Championship table, three points behind leaders Leigh.
Batley remain third but are now just a point ahead of West Yorkshire rivals Bradford Bulls and Featherstone Rovers, who both picked up victories last Sunday.
