Tykes director of rugby Phil Davies hailed Braam Van Straaten's faultless kicking display as "world class" as London Irish followed champions Leicester to defeat at Headingley this afternoon.

Van Straaten, who was injured early on in last week's victory over the Tigers, leaving fly-half Gordon Ross to take over the duties, returned to land nine penalties and two conversions - a 100record - as the Tykes romped to a 41-16 triumph.

He scored 31 of the Tykes' points to set a new club record and the nine penalties equalled the Premiership best.

He even spurned the opportunity of a 10th in injury-time as Leeds opted for touch to seal an impressive win.

"He put on a world class display out there," said Davies, who brought Van Straaten to the club midway through last season.

"You have to give credit to the whole team for getting us into positions and putting the pressure on so London Irish infringed, and Braam duly obliged and kicked everything that was offered to him.

"He showed his worth for us with an immaculate kicking display."

Van Straaten remembers his best return as a faultless 10 from 10 playing back in South Africa for the Stormers against the Bulls at the Loftus Versfeld.

This, however, ranks alongside the former Springbok's best displays and he was delighted his hard work and dedication paid off.

"I've been working on my angles to get a better strike on the ball and today it came right. I have been striking it sweetly," he said.

"I don't feel the pressure when I'm kicking, it's my job and I've done it all my life. It's good for me to see how good I strike the ball, sometimes it goes through the posts and I'm not happy with the strike.

"I'm very critical of myself - like Jonny Wilkinson I like to get everything over."

London Irish director of rugby Conor O'Shea reserved his own criticism for the Exiles' lack of discipline, which allowed Van Straaten the opportunity for such an immaculate display.

"We knew from the Wasps-Newcastle game last week where Robin Goodliffe was referee that it was on the ground where he would be at his most strictest. Our discipline was very poor," he said.

He added: "I'm sure a few of the decisions were 50-50 but the majority of them were correct and we are going to have to work on that.

"At 19-16, 10 minutes into the second half with a breeze behind us it was an even game and to be honest we came apart at the seams.

"We gave away penalties, they kicked the goals and 19-16 became 22, 25, 28 and then a try.

"Fair play to Leeds, they are very very good side. Their pack is very physical, well drilled, their 10 (Gordon Ross) controls the game and they have a goalkicker to rival any in history of world rugby and they have got a back three to die for.

"There will be many a side who will struggle up here but you have to keep your discipline."
