Sam Johnson went over for a superb opening try

The Warriors had been usurped at the summit on Friday when Munster won at Benetton but they are now back on top with one round to play.

Tries from Sam Johnson, Tommy Seymour, Matt Fagerson, Zander Fagerson and George Horne saw them to a fine away bonus-point success.

Leinster's cause wasn't helped early on by fly-half Ross Byrne being yellow carded after only three minutes for tackling Seymour without the ball, Adam Hastings sending over the resulting penalty for a 3-0 lead for the Warriors. The fly-half would go on to finish with 14 points.

The Irish did respond five minutes later when Dave Kearney crossed but Joe Tomane was wayward with the extras, meaning they led by two.

Hastings would nudge his side back in front before a wonderful break from Ali Price on his own 22 led to Johnson fending en route to a try. With Hastings' two the Warriors had raced into a 13-5 lead in Dublin and were looking in good shape with a quarter of the game gone.

Leinster managed to score next when sustained pressure in the Glasgow 22 led to Rob Kearney crossing. However, the half would end with Glasgow grabbing their second try of the day as a wonderfully timed pass from Hastings to right wing Seymour saw him make it 18-12.

Rob Kearney would get his second 10 minutes into the second period after another multi-phase play from Leinster which took them ahead.

The family affair continued when brother, Dave, also picked up his brace but Glasgow did respond via their pack as Matt Fagerson crossed for the lead, which was built on soon after as Zander Fagerson powered over the whitewash. Suddenly Glasgow were in front, 32-24.

And the icing was then added by replacement Horne, whose intercept crossing made it a five-try victory for Dave Rennie's men on the road.
