CULT HERO Niko Matawalu came off the bench to inspire the Warriors to a brilliant win to boost their Pro12 play-off hopes.
Gregor Townsend’s troops had been toiling to snatch a precious bonus point, despite being in total control at Scotstoun. But the dynamic Fijian darted over to snuff out the jitters and make sure of the full haul.
Glasgow coach Townsend said: “Before the kick-off, we would have taken a one-point win, so to come out of it with a maximum haul was a tremendous outcome.
“Obviously it had been a disappointment not to get any bonus points against Edinburgh, so this was really pleasing.”
Glasgow made an urgent start with Alex Dunbar immediately testing the Italian markers. His efforts pressured them into giving away a penalty, which was confidently slotted by Ruaridh Jackson.
There was high drama just seconds after the restart when Treviso flanker Manoa Vosawai was shown a straight red card by Irish ref Leo Colgan for a tip-tackle on home skipper Al Kellock.
Despite being a man down, the visitors showed tremendous bravery in defence as the Warriors stepped up the pace.
It was only another penalty by Jackson that enabled them to stretch their lead midway through the half.
Then came the moment the Glasgow fans were waiting for as they created their first touchdown.
Tommy Seymour was at risk of wasting the chance when he chipped into space instead of using his support runners.
But winger Dan van der Merwe was in the right place at the right time to scoop it up and finish the move, Jackson adding the extras.
Even better was to come two minutes later as they broke through again.
A long kick by Jackson sparked panic in the Treviso back ranks and when they failed to clear the danger it created the space for Stuart Hogg to pounce.
Having inflicted the initial damage, Jackson followed up with the conversion to widen the gap to 20 points.
The crowd were on their feet again just before the break as Seymour intercepted a pass close to his own line and cruised 90 metres to give Jackson a simple kick.
Glasgow took their foot off the gas after the restart and lock Francesco Minto sneaked in for a Treviso score out of the blue. Kris Burton converted.
Only a last-gasp tackle by Matawalu stopped them claiming another as the Warriors’ shoddy spell continued.
Then he did the business at the other end with a fourth try for Glasgow. Duncan Weir converted from a wide angle.
There was still time for Hogg to take the home try tally to five.
