So none of the sloppiness in Glasgow's game that allowed Zebre to make a game of it when the sides met back in May.
Warriors have not been spectacular but are firmly in control and it would be something of a miracle if they fail to secure the maximum five points here.
Jack Dempsey has had some monstrous carries, Jamie Dobie and Huw Jones finished their tries well and there's a sense that as comfortable as they are, Glasgow can move it up a few gears if required.
In other news, there's a very entertaining game of touch rugby going on at half-time. End-to-end stuff!

It's patient stuff again from Franco Smith's side, going through the phases, stretching the Zebre defence and then finding a gap.

Zebre are on the board.

Jamie Dobie
Stafford McDowall sends Jamie Dobie over in the corner for Glasgow's second try, but it was all about the initial break.
Huw Jones bursts through a tackle, before George Horne exchanges passes with Kyle Rowe.

There he is!

Adam Hastings converts.
