Sam Davies' disallowed try was the main talking point at the end of Connacht's hard-fought 30-22 Guinness PRO12 win over the Ospreys at the Sportsground.
The Ospreys were left seething at the Sportsground after their fly-half's 63rd-minute effort was ruled out by the match officials for a double movement.
Although replays showed that tackler Kieran Marmion had lost his grip on Davies, referee George Clancy and TMO Jude Quinn disallowed it. Had he scored, the Ospreys would have tie things up at 27-27.
Connacht were always likely to bounce back, though, and a final penalty from Craig Ronaldson put them out of the visitors' reach.
A fast-paced and hugely entertaining first half delivered four tries, early scores from man of the match Bundee Aki and AJ MacGinty making it 14-3 before the Ospreys hit back through Ben John and Dan Baker.
A Ronaldson penalty saw the westerners retake the lead for half-time at 17-15 and the tries kept coming through Matt Healy and the fit-again Rhys Webb.
The PRO12 leaders managed to keep their noses in front and two more place-kicks from Ronaldson, coupled with some tigerish defending, saw them take a step closer to the play-offs and Champions Cup qualification.
