Ospreys wing Hanno Dirksen races away for the game's first try
Ospreys edged their dead-rubber LV= Cup game against Leeds in front of 2,557 fans at the Liberty Stadium in Swansea.
After Joe Ford's penalty for Leeds, Hanno Dirksen put Ospreys ahead as the wing broke through and then followed up the move in support to barge over.
Flanker Steve Tandy then slid over for the Welshmen, but Leeds trailed 14-10 at half-time thanks to Erik Lund's try.
Jamie Nutbrown squirted over from a set scrum move, giving Ospreys a winning lead despite a late Leeds penalty try.
