The Ospreys' hopes of a late season surge up the United Rugby Championship table were hit as a missed conversion denied them a comeback victory over Benetton at the Swansea.com Stadium.
Trying to move on from the 58-3 hammering against Munster, Toby Booth's side had floundered for much of the night - trailing 21-8 heading into the final stages despite Luke Morgan's early score.
However, late tries from Sam Parry and Reuben Morgan-Williams gave them a sniff of a victory that would have boosted their chances of toppling Cardiff in the Welsh Shield stakes, only for the conversion from out wide to hit the post.
