Dan Evans' converted try 11 minutes from time earned Ospreys a 20-20 draw in their Pro12 meeting with Glasgow Warriors at the Liberty Stadium on Sunday.
The Welsh side found themselves 20-13 down against the defending champions, but rescued two points thanks to Evans' score and Sam Davies' conversion.
Eli Walker's try had seen Ospreys lead 10-6 after 25 minutes, but Rory Hughes responded quickly for the Warriors, who extended their lead in the second period with Gordon Reid's score before Evans' timely intervention.
A pair of Duncan Weir penalties had Glasgow 6-0 up early on, but Ospreys moved in front thanks to Davies' kick and a try from Walker, who broke free from 20 metres out and went in under the posts.
Their lead was short-lived, however, as the Warriors worked the ball left for Hughes to touch down in the corner, Weir adding the extras to make it 13-10 at the break.
After a Davies penalty brought Ospreys level soon after the restart, the Warriors moved back in front as Reid burrowed over, but Evans was able to cross the whitewash to leave Ospreys seventh, one place ahead of their opponents.
