Dan marked his return to the Glasgow side with the side's first try

Glasgow Warriors coach Sean Lineen said, "It wasn't a classic game of rugby and it was very loose.

"We didn't have the physicality that we demanded and our defence was pretty paper thin at times.

"We came here to get a bonus point and we got it. Unfortunately, I think Ospreys got one as well, so that is us in third at the moment.

"Over the season, we have made huge strides and I am really proud of the way they have stuck together through the season.

"We need to raise our game at least four or five levels to compete with whoever we play against because the teams that are left in are incredibly physical."

Glasgow fans face an anxious 48-hour wait to find out the venue of the Warriors’ Magners League semi-final play-off following tonight’s 37-32 win over the Scarlets.

Despite achieving their ultimate goal of recording a four-try bonus point victory in Llanelli, results elsewhere – notably the Ospreys’ bonus point win over the Dragons - means that plans are on hold until Sunday’s matches determine final placings for the knock-out stages.

In a match strewn with moments of brilliance and blunder on both sides, Glasgow remained the better team throughout and sealed a gutsy win to keep them in the hunt for home advantage next weekend.

Just three minutes into the match, Glasgow looked odds-on favourites to open the scoring.

Hooker Fergus Thomson peeled round from a Warriors line-out and proceeded to power through the Scarlets defence.

Having made significant ground, he was brought down little more than five metres from the whitewash where an offload to Chris Cusiter was popped to Hefin O’Hare who darted behind the posts. However, Welsh referee James Jones disallowed the try and brought play back having deemed the penultimate pass to have been forward.

For all Glasgow’s efforts in the first ten minutes, it was to be the home side that scored first. A simple overlap was crafted out wide where fullback Daniel Evans received the ball and dotted down. Stephen Jones missed the conversion.

Dan Parks’ penalty in the ninth minute registered Glasgow’s initial points before winger DTH van der Merwe cut a searing angle to burst through in midfield and round the fullback only four minutes later. Parks converted.

Stephen Jones was successful with his second attempt at goal, this time a penalty in the 17th minute.

Twelve minutes were to pass before the scoreboard moved again. From a penalty inside the Glasgow half, Dan Parks sent the ball into touch and the visitors went through the phases before choosing to attack on the blind side.

Glasgow’s attack whipped back where Calum Forrester took a long pass from Parks at pace to slice through the line and he ran for Glasgow’s second try. Parks converted.

Just before the break, the Warriors found themselves a man down as James Jones sent Kelly Brown to the sin bin for a professional foul.

With the Scotland back-rower in the bin, the Scarlets scored a Stephen Jones penalty and two tries - one either side of half-time.

The first came from winger Lee Williams. A scrappy attack from the home side eventually found Williams tight in the corner, and despite the best efforts of Graeme Morrison, the winger managed to ground the ball.

As Stephen Jones had been announced as the highest ever points scorer in Scarlets history in the first half, he celebrated by grabbing a try in the second.

An odd decision for two Glasgow defenders to mark the blind side, which contained no opposition, created a mismatch on the other side of the set-piece.

A short pass out of the scrum to Jones left him with an easy jaunt to the try line. He converted his own score.

As Kelly Brown returned to the field, Dan Parks continued to keep Glasgow ticking with two further penalties in a four minute period.

Stephen Jones replied with two of his own, but Glasgow’s job to secure the bonus point was only half done.

Hefin O’Hare, who had already collected the gong for try of the season at an awards ceremony last week, backed his credentials with another contender.

He received the ball 10 metres inside his own half and weaved up the flank. Choosing not to use the players in support, he stepped inside and danced his way between the posts. Parks converted.

Ever the man of the people, it was fullback Bernardo Stortoni who was to record Glasgow’s crucial fourth try and the resulting bonus point.

A high cross-field kick from Parks was plucked out of the air by the Argentine who darted in for the score. Parks converted as Glasgow sought to see out the remaining 10 minutes unscathed in order to seal the victory.

The only scar came four minutes from time as Jones slotted his fifth penalty, but it was too little too late for the Scarlets.

All eyes will now be on Edinburgh’s trip to the RDS in Dublin where they face European champions Leinster.

A win for Edinburgh would hand Glasgow a home tie, a win for Leinster would point to an away semi-final play-off with the Ospreys at the Liberty Stadium.
