Clegg the hero in Warriors win

Clegg scored within three minutes of his introduction to move his side into the top four on the Pro12 standings.

Glasgow had looked in control after responding to Luca Sperandio’s second-minute try, with Stuart Hogg – making his first start at flyhalf in the Pro12 – pulling the strings.

The Scotland fullback, Tommy Seymour and the fit-again Adam Ashe all piled over before the half was out, but a Dean Budd try and Tommaso Allan’s kicking kept Treviso in touch.

Nick Grigg looked to have settled the game in the second half only for Budd to complete his try-double, with replacement Ian McKinley’s conversion levelling the scores.

Then Clegg, on for Grigg, broke Treviso’s hearts by crossing just two minutes later as Glasgow saw the last five minutes out.

Though 11th in the table, Treviso were not to be underestimated as they were aiming for their fourth victory in a row in all competitions.

And wing Sperandio got the Italians off to the perfect start by finishing a slick move in the corner with just two minutes on the clock.

The conversion was missed by flyhalf Allan and then his opposite number Hogg set about trying to cancel out the deficit.

The Scotland fullback made an initial burst to put Treviso under pressure inside their own 22 – but a penalty flipped the momentum on its head.

Eventually, with the Italians camped on the Warriors line, the ball was spilled and Hogg hared up the pitch to score and then convert his own try.

Barely two minutes had gone before Glasgow scored again – this time Peter Murchie providing the inspiration, before the ball found its way to Seymour for his eighth try of the season.

Treviso continued to look dangerous, but after Allan missed a penalty in front of the posts, the Warriors made them pay.

Ashe – making his first start of the season – batted away a defender and crossed after taking on Tim Swinson’s pass, and suddenly Glasgow were 21-5 up on the half-hour.

Back came Treviso, however, after Budd got the first touch to a loose Glasgow pass that had ended up over their own try-line.

Junior Bulumakau nearly grabbed a Glasgow try-bonus point before the break but could not quite get on the end of a chip – instead Allan cut the half-time deficit to six points with a penalty.

Treviso started the second half on the front foot and Allan slotted one penalty from two, but Glasgow soon got their bonus point.

And the Warriors’ fourth try was arguably their best as Grigg showed tremendous power to bully his way over the line before Hogg’s conversion opened up a ten-point gap.

The hosts refused to give up and, following McKinley’s penalty, forced Glasgow to scramble and touch down over their own line.

In a bizarre passage of play Treviso won a penalty from a five-metre scrum and the kick hit the post, which then was adjudged to have rebounded off a Glasgow player for a knock-on.

Another penalty was rewarded and Budd scored through a quick-thinking tap-and-go – but Treviso’s joy would be short-lived.

Clegg, only just on the field, was at the right place at the right time to finish off another lightning Glasgow move and there was to be no way back for the home side after Hogg’s conversion.
