Glasgow Warriors 18 - 21 Ospreys: Dan Parks overhauled David Humphreys� Magners League points record and Thom Evans scored two tries but it was the Ospreys who were celebrating as the leaders continued their fine start to the season.

Dan Parks overhauled David Humphreys' Magners League points record and Thom Evans scored two tries but it was the Ospreys who were celebrating as the leaders continued their fine start to the season.

Their third straight win ended the Warriors six match winning streak in league games and it was a result they thoroughly deserved.

With the home support eager to acclaim Parks setting a new Magners League points-scoring record the opportunity arrived within two minutes. However it was groans rather than roars which greeted his long-range attempt as he pulled it wide.

When Ospreys Daniel Biggar, making his league debut, got a chance from similar range, albeit an easier angle, in 15 minutes the youngster struck the target to put his side ahead.

Parks then fell short with a long-range drop goal attempt and, the referee having been playing an advantage, he again nervously dragged the penalty attempt left.

Nor was he the only member of the home team who was struggling: the pack was being bullied at the breakdown, allowing Ospreys the chance to set up the first try.

Deft handling was allied to powerful running as they sucked in defenders while shifting the ball right until it reached Kristian Philips, who had replaced the injured Gareth Owen after just five minutes. He took it at pace, chipped it neatly over Evans and gathered on the full before battling his way through John Barclay's tackle to cross.

With the pressure building, Parks missed again from long range, this time slapping the ball right and when yet another chance was offered he opted instead to kick to touch.

That lifted the crowd and Warriors responded, setting up a furious attack which took them through over a dozen phases inside the opposition 22, yet the defensive line held.

It was becoming tense inside the ground but at last the moment came in 33 minutes when good work by Barclay and Kelly Brown earned another penalty close to the opposition 10 metre line and Parks had the courage and technique to send it through the posts, drawing a rapturous response from the Firhill faithful and easing the tension.

That was nothing to the roar that greeted Warriors' first try of the season two minutes into injury time. Mark McMillan initiated it, spotting space behind a ruck just inside the 22 and hooking the ball delicately into it.

It bounced perfectly for Evans to run onto and the winger's pace saw him round the last man with ease to go over for a try that Parks converted.

Given the overall nature of the first half, a 10-8 Warriors lead was a surprising scoreline.

Yet had Parks been on form they might have been well clear, but instead he missed again from five metres inside his own half after the break.

Once again young Biggar was swift to show up the new league record holder as he blasted over a drop goal from inside his half to reclaim the lead before extending it with his second penalty success.

Parks did, however, cut the deficit to a single point when his side was awarded a penalty under the posts with 12 minutes remaining.

The Warriors were given a further boost when, with eight minutes remaining and team warnings having been issued about the number of penalties Ospreys were conceding, their scrum-half Jamie Nutbrown was sin-binned.

They capitalised on the extra man almost immediately.

Parks showed his vision to realise that, as he received the ball from a lineout on the right, Evans was clear on the left and he found him with a perfectly-weighted kick which he took at full tilt before racing away from Johnny Vaughton to score in the left corner.

However Parks missed the conversion attempt and when, with his side hanging on, Steve Swindall followed Nutbrown into the sin bin the Ospreys saw their chance.

Awarded a penalty as a result they kicked to touch and, after a succession of drives, Alun Wyn Jones powered over on the left to score the try, converted by James Hook, that won the match.
