Pro12: Dan Biggar hails Ospreys 'best' display in win over Ulster

Dan Biggar is halted by Ulster's Mike Allen and Ruan Pienaar

Fly-half Dan Biggar says Ospreys produced their best display of the season in Saturday's bonus-point win over Ulster that returned Ospreys to the top of the Pro12 table.

Biggar scored the first of four home tries and kicked a penalty and four conversions in the 31-20 win.

He said: "The first hour was good. We played probably the best rugby we've played all year."

Scrum-half Rhys Webb went over twice, with wing Hanno Dirksen also crossing.

"We played some good phases together, we played some continuity," said Biggar.

"We interlinked forwards and backs well."

Ulster fought back from 31-6 down after 56 minutes with tries by Rob Herring and former Ospreys wing Tommy Bowe.

Biggar says he and his team-mates were "a little bit disappointed that we let them back into it".

The Wales fly-half added: "[We] weren't hanging on at the end, as such, but we were under the pump, certainly.

"So, pleased to come through and it puts us top… and we can't ask for much better than that.

"We've defied the odds against everyone else and it's just positive.

"We're in a good place. We're enjoying each other's company.

"We're enjoying playing together and hopefully we can continue that."

And Biggar believes their bonus point could prove to be vital when the top four play-off places are settled.

He said: "We've missed out the last couple of years on four points or whatever it is - it's one win - and I think it's been a good sort of couple of weeks for us in terms of performance-wise.

"We're just happy to get the result and points… and that extra point could prove crucial over the course of the year."

The win sets up Ospreys for next Saturday's west Wales derby at home to Scarlets, who lost 21-9 at Cardiff Blues on Friday night.
