Ospreys survived an unlikely Edinburgh fightback to clinch a Celtic League victory at the Liberty Stadium.
Ospreys (18) 24:
Tries: Bennett, Connor
Pens: Henson (4)
Edinburgh (3) 17:
Tries: Webster, Jorgensen
Cons: Hodge (2)
First-half tries from Huw Bennett and Shaun Connor, together with 14 points from Gavin Henson's boot put the home side clear at 24-3 after 50 minutes.
Edinburgh were camped in the Ospreys half for the rest of the match and were rewarded with two late converted tries.
Simon Webster and Peter Jorgensen scored to give the visitors hope, but 13-man Ospreys held on to win.
There was a nasty undercurrent to the opening exchanges, which threatened to boil over on a few occasions.
Some over-zealous rucking inevitably led to a string of penalties and it was the Ospreys who capitalised best as Henson landed both his attempts while Godman just one inside the first 20 minutes.
The Ospreys, growing in confidence, spurned another opportunity to go for the posts on the half hour mark and their adventure was rewarded with a try.
Lock Ian Evans secured quality lineout ball deep inside Edinburgh territory, and the visitors had no answer to the subsequent driving maul which saw hooker Bennett score. Henson converted.
A great deal more skill and flair was on show four minutes later as the home side scored their second try.
Centre Sonny Parker made the all-important midfield break, and flanker Des Dillon's perfectly timed pass allowed fly-half Connor to finish off a sweeping move in the left corner.
Henson failed to add the extra points, but the centre kicked two quick penalties shortly after the break to take the Ospreys clear at 24-3.
Edinburgh spent most of their half inside Ospreys territory, but a combination of solid defending and unimaginative attacking stopped them scoring.
But the pressure finally told inside a frantic last 10 minutes as the visitors scored twice.
Winger Webster sliced through a tired defence and beat the last man for pace to score the first, and centre Jorgensen finished off a fine move under the posts for the second.
Duncan Hodge converted both to cut the gap to seven, but the Ospreys held on for the win despite having two men in the sin-bin.
