Ospreys eased to a comfortable Magners League win against Glasgow at the Liberty Stadium on Friday night.
Tries from Nikki Walker, Sonny Parker, Steve Tandy and Shane Williams, with three converted by Gavin Henson, earned Ospreys a bonus point in victory.
Glasgow fly-half Colin Gregor had looked assured and slotted three first-half penalties for the Scots.
But his early injury withdrawal was a blow for the visitors, who struggled to discover any cutting edge.
A lacklustre start by the Ospreys saw Glasgow open up a 6-0 lead through two Gregor penalties.
But a moment of individual brilliance from James Hook gave the home side the kick-start they needed.
The 21-year-old centre picked up a loose ball one-handed and raced through between the Glasgow chasers.
We just turned up tonight and weren't quite there, we looked like a team that hadn't played for a fortnight
Open-side flanker Tandy provided the link and Walker raced under the posts, Henson converting to make up for an earlier penalty miss.
Gregor added a third Glasgow penalty to edge the Scots back in front, but pulled something in taking the kick and was replaced by Dan Parks.
The Scotland cap had to wait to get the ball in his hands as the Ospreys marched upfield for their second try, Parker eventually crashing over from close range for a seven-pointer.
As the half-hour mark arrived the Welsh scored again, Filo Tiatia - a late replacement for Ryan Jones - and Brent Cockbain combining to set Justin Marshall bounding towards the whitewash.
Thom Evans did well to drag the former All Blacks scrum-half down just short but Tandy was on hand to pick up and dive over, Henson again adding the extras.
Glasgow changed their tactics after half-time and with a series of grubber-kicks tried to pin Ospreys back.
But Glasgow's tactic of giving up what possession they had earned simply encouraged the Ospreys to go searching for the fourth try that would earn a bonus point.
Clean breaks by Williams and Henson foundered just short, while lock Ian Evans was held up over the line.
But with three minutes remaining the Ospreys spun the ball from a scrum along a backline full of movement and angled runners.
Henson's long pass found Williams, who did brilliantly to pick up from his toes and squeeze in at the right corner for a fourth try and bonus point.
Ospreys coach Lyn Jones:
"Two weeks ago we were here against Gloucester, knew we were up against it and it brought the best out of us.
"We just turned up tonight and weren't quite there, we looked like a team that hadn't played for a fortnight.
"But we were very pleased to score four tries and get the win."
