Josh McKay's try proved to be the pivotal moment in Glasgow's win

As well as lifting them to third in the URC table, the win also gives Warriors a 30-17 advantage to take into the second leg of the 1872 Cup.

Elsewhere, scored a double before limping off as the Warriors beat Edinburgh 30-17 at Scotstoun.

Glasgow flanker Tom Gordon - who eventually limped off - twice put the hosts in front before Glen Young and Boan Venter responded.

The pivotal moment proved to be a breakaway try from Josh McKay in the 56th minute which saw the home side go on to dominate possession and close out the win.

Glasgow started the quicker of the two teams and might have scored even earlier than their ninth-minute opener.

A stolen line-out and a deliberate knock-on from Edinburgh winger Emiliano Boffelli, who escaped a yellow card, held up Warriors before the combined efforts of Henry Immelman and Matt Currie stopped Cole Forbes going over in the corner.

The breakthrough came from some close-range pressure when Gordon wriggled over.

Glasgow failed to deal with Edinburgh's kick-off when Jack Dempsey let the ball bounce and McKay's kick was charged down behind the try line. Edinburgh turned the screw in the corner and Glen Young eventually converted the pressure in the 14th minute despite Johnny Matthews' efforts to hold the ball up.

The Warriors got back on top and it was a mistake from the visitors that led to the third try of the game in the 29th minute.

Jaco van der Walt's kick was flat and short and straight into the hands of Sebastian Cancelliere. The wing fed Stafford McDowall, who set up Gordon to go over after a dummy.

Edinburgh responded positively and McKay did well to hold up Currie after the centre burst through the lines. Edinburgh cut the gap through Boffelli's penalty, but Weir restored the Glasgow's seven-point lead just before the interval.

Edinburgh re-started strongly and benefited from a second penalty in quick succession when Venter went over. Boffelli levelled the scores.

The game turned on Cancelliere picking up a loose ball inside his own half as Edinburgh attacked. The Argentinian wing drove forward and infield knowing that McKay was overlapping and his clever no-look pass took three Edinburgh players out the game as the full-back ran up the right wing to cross.

The Warriors got some more control of the game, with substitute Ross Thompson's kicking adding eight further points as well as keeping Edinburgh on the back foot.
