Glasgow Warriors rallied from 13-0 down at half-time to secure victory over Cardiff and move up to second in the United Rugby Championship table.

Max Williamson and Lucio Sordoni crossed early in the second half as the hosts turned the tide, with Duncan Weir kicking the rest of Glasgow's points.

Warriors move a point behind leaders Leinster, while Cardiff remain 12th.

A foul evening in Glasgow made life difficult for both teams early on but the home side had the worst of it, playing into a strong wind that made it hard to break out of their own territory.

De Beer booted Cardiff into an early lead and while they had to withstand a short period of pressure on their own line, Warriors' inability to deal with the conditions meant the Welsh side were comfortable in defence for the most part.

De Beer banged over another penalty to put the visitors 6-0 in front and they really should have burnished their advantage with a try, but two or three goes at the Glasgow line were repelled by stout defending.

The reprieve was only temporary. A great burst from Thomas Young cut through the Glasgow defence and some brilliant offloading set-up Thomas to go over.

Glasgow came roaring out the blocks after the break. Kyle Steyn made good inroads before Williamson surged to the line with tremendous power to give Franco Smith's men a much-needed foothold with his first try for the club.

The home side were warming to their task, with Jack Dempsey's powerful carrying in particular setting the agenda.

They were over again a few minutes later, Sordoni burrowing down from close range for his first try in Warriors colours, and Weir's conversion nudged Glasgow ahead for the first time.

The fly-half struck again with a penalty to make it a four-point game at 17-13.

Steyn thought he had put the match to bed by finishing off a lovely move, but the try was ruled out for a forward pass in the build-up from Josh McKay.

Glasgow needed another two tries for the bonus point that would have taken them top of the table, but that never really looked like materialising. From where they were at the break, four points was prize enough.

'Shellshocked' Glasgow respond well - reaction

Glasgow head coach Franco Smith: "I'm glad in these conditions we were still able to get it done, especially from 13-0 down.

"We had opportunities we didn't convert. I just felt we were a little bit shellshocked in the first half and it was about focusing our energy and enthusiasm and physicality in certain areas, which the guys did well.

"Disappointed not to get the bonus point but it was a very tough Cardiff side and it was never going to be easy for us."

Cardiff head coach Matt Sherratt told Viaplay: "It's a bittersweet one because we had chances to win it. We got pushed into touch twice five metres from their line, held up twice over the line.

"We're the first team in the league to get a point at Glasgow away - Leinster have been here, Stormers have been here. The challenge for the players was can we replicate what we've done at the Arms Park.

"To come to Glasgow, one of the toughest places in the league, and get something is all credit to the players."
