The Ospreys survived a mighty scare at the hands of Italian side Zebre as they held off their visitors 16-15 at Liberty Stadium in Swansea on Friday.
Despite having not won a game all season, the visitors went into the interval in front as scrum-half Alberto Chillon knocked over an early penalty and followed that up with a close range try just before the half-hour mark.
The Ospreys, who were on a run of eight straight home wins, were surprisingly lacklustre in comparison and could only muster two penalties from the boot of Dan Biggar in response before the break.
The home side would have fancied their chances at the start of the second half after Zebre had South African number eight Dries van Schalkwyk sin-binned three minutes before half-time but they failed to capitalise on having an extra man.
Biggar did edge them ahead with another three points going into the final quarter of an hour of the match and the Welsh international fly-half made the crucial breakthrough moments later as he finished off a flowing move to score the hosts' only try of the night.
Tito Tebaldi made it a very nervous last ten minutes for the Ospreys as he responded with a try of his own almost immediately to narrow the gap to just a solitary point but the Welshmen held on to move into the top four places in the table.
