A Thom Evans double helped Glasgow to a valuable away win

Evans' first-half try was a team effort, but his crucial second-half score came from the individual skill of Dan Parks.

The fly-half's pin-point cross-kick sent Evans over to ensure victory.

Glasgow took the game to the Dragons from the outset with half-backs Sam Pinder and Dan Parks setting their backs free at every opportunity.

The approach brought the best out of sibling wings Thom and Max Evans, the former claiming the first try after 19 minutes following some excellent inter-lay between forwards and backs.

Parks' conversion was soon followed by his penalty after referee Alain Roland told Dragons skipper Colin Charvis to warn his players about a series of offences, including tripping.

Dragons fly-half Aled Thomas provided some nice touches, but was also guilty of poor defence in the opening quarter.

The Welsh region also struggled to make the most of their chances despite the attacking talent at their disposal.

However, that all changed after Thomas kicked two penalties. The scores gave Paul Turner's side some confidence and they began to attack with more purpose.

Centre Rhodri Gomer-Davies drew two defenders to create the space for Kevin Morgan and Gareth Wyatt to combine in a manner with which their followers from the days in which they starred for Pontypridd would be familiar.

Morgan's final pass set Wyatt free down the right and the wing was too quick for the cover defence.

Thomas was unable to convert the 31st-minute try, but added a penalty to send his side into the break 14-10 ahead.

Parks closed the gap 15 minutes in the second period after prop Rhys Thomas was caught offside, but the visitors were soon back in trouble.

Dragons flanker Joe Bearman's speculative punt was harmless until full-back Bernardo Stortoni knocked on, but the hosts blew the opportunity amid more indiscipline.

At the other end Parks' long pass to unmarked Stortoni was judged forward as Glasgow sought to get back into the lead.

When they did so it was spectacular as Parks' cross-kick from one touchline found Thom Evans a few feet from the other and the wing went over unopposed for his second try.

Parks converted, but failed with a drop-goal attempt after 70 minutes to leave the outcome finely balanced.

Paul Emerick cut replacement Hefin O'Hare down before snaffling possession at the subsequent ruck to help the Dragons find themselves in Glasgow's 22.

That was the start of a desperate late assault from the hosts and despite the best efforts of the likes of replacements Martyn Thomas and Michael Owen the Dragons could not break free while Glasgow defended superbly.

Glasgow coach Sean Lineen said with a smile: "It wasn't pretty but we'll take the win.

"We're delighted because that's our first away win of the season and we must keep that going.

"Our local derby versus Edinburgh is our next fixture, they beat us over Christmas in the last minute and we're looking to redeem ourselves after that defeat."
