Hogg's late strike sees Leinster fall to Warriors
It was re-run of last season's PRO12 final but this time Glasgow Warriors had the better of things to the tune of 22-20 with another game which was decided in its final minute.
Stuart Hogg's late, late penalty ensured that the Warriors got off to the ideal start after they had come close to blowing it all after Leinster hauled back the home side's 19-0 lead.
Indeed, Leinster hit back with a penalty from Ian Madigan and tries courtesy of subs Jack McGrath and Tom Denton, which were both converted by Jimmy Gopperth, who also managed his own penalty, to go 20-19 in front which seemed as if it might snatch it until Hogg's dramatic intervention from the tee.
Optimism has been in plentiful supply around Connacht – what with Mils Muliaina in Galway but not yet fit to play – and they duly delivered with Pat Lam overseeing a 16-11 victory over the Dragons at the Sportsground to become the only Irish province to win on the first weekend..
It was nip and tuck but Jack Carty's cross-kick for Danie Poolman brought the westerners a critical try while the Dragons were down to 13 men. Eoin McKeon got Connacht's other try while Darragh Leader landed two penalties for the four-point haul.
Meanwhile, on Friday night, Munster fell to a shock 14-13 defeat at the hands of Edinburgh at Thomond Park of all places.
Despite CJ Stander crossing the Scots' line twice, Alan Solomons' side held on and deserved the four points despite Ian Keatley's poor kicking display which could have stolen it for Brendan Foley's first competitive game in charge.
The Ospreys had things rather easy in their 44-13 five-try whipping of Benetton Treviso with Dan Biggar kicking 17 points of the home side's total at the Liberty Stadium while, yesterday, Cardiff Blues opened their campaign at Zebre by winning 41-26.
