Peter Horne kicked Glasgow's points

Scarlets went into the break 9-3 ahead after penalties from Steven Shingler with Glasgow's Peter Horne putting over one of his own.

Horne responded with two more penalties to bring the scores level again on the hour mark before Shingler restored Scarlets' lead minutes later with another three-pointer.

The Warriors looked like taking at least a losing bonus-point from the game but a late try from former Glasgow forward Rory Pitman secured the win for Scarlets.

Following the 19-9 defeat to Scarlets, only Glasgow's second loss of the season, Gregor Townsend looked back on the game with disappointment.

After the game, head coach Gregor Townsend said: "It was a frustrating night as we had trained and prepared really well but just weren't consistent enough during the game.

"There were times when we did show real energy and played tactically well but there were other times, especially when we didn't have the ball, where we dropped below the required standard.

"It was a shame we couldn't kick on once we got to 9-9 and Scarlets ended up controlling the last 20 minutes."

Glasgow gave debuts to Ali Price and Glenn Bryce, brother of hooker Kevin, and Zander Fagerson made his first start for the club.

Gregor said: "I thought Ali played well on his debut and looked sharp. He was replaced by Niko (Matawalu) at half-time because we wanted to give Niko a decent amount of game time after he returned from international duty on Thursday.

"Zander made some excellent contributions in the first half but seemed to get himself on the wrong side of the referee at scrum time.

"It was nice to get Glenn (Bryce) on near the end to play alongside his brother.

"Glenn, Ali and Zander have trained well and we expect them to get more involvements with the senior squad later this season."

Next Sunday, the Warriors take on Newport Gwent Dragons, kick-off 2.30pm at Scotstoun Stadium and it's a game Gregor is looking forward to, giving his side an opportunity to bounce back.

He said: "We know we have to keep working hard, no matter who we're playing and the time of the season.

"It was tough against Scarlets as our players don't like losing and not playing to their potential but next week we have another opportunity.

"The Dragons will come to Scotstoun in the knowledge they beat us last year so we'll need to be strong.

"The match is our last before December which is a huge month.

"There were a few players who did well against the Scarlets and put their hands up for possible selection for those key games."
