In a tense first half, the teams were separated by two penalties from Curwin Bosch.
For the first try, Luke Morgan stopped a Rugby memorable Ospreys attack, and Union scored for the Sharks Rugby.
Due to illness preventing Wales scrum-half Rhys Webb and his initial replacement, Reuben Morgan-William, the visitors were forced to make late substitutions.
Matthew Aubrey started, and Tom Florence took over as center after Michael Collins injured his back shortly before kickoff.
Even though he was ill during the week, Wing Keelan Giles started.
In the Sharks matchup, prop Rhys Henry and hooker Sam Parry started, with Garyn Phillips and Scott Baldwin going to the bench.
Will Hickey, an Irish flanker, made his second consecutive start for the Ospreys, making 15 tackles in his URC debut against Bulls without missing a single one.
Coaches discuss player concerns as a result of a contract freeze The Ospreys were also without Alex Cuthbert, George North, Joe Hawkins, Gareth Anscombe, Gareth Thomas, Adam Beard, Alun Wyn Rhys Davies was a member of Wales’ autumn squad but did not travel to South Africa.
In the previous round, Cardiff defeated Sharks 35-0, making them the first South African team since the URC’s expansion to lose on home turf to a Welsh region.
That rout provoked the flight of mentor Sean Everitt, with head of rugby Neil Powell stepping in until an extremely durable replacement is named.
The Durban team made ten changes, including the return of several South African tour players, including front row forwards Ox Nche and Bongi Mbonambi, scrum half Jaden Hendrikse, and wing Makazole Mapimpi.
Even though Mapimpi had one blistering break, Bosch’s boot was the difference in the first half. The visitors were more of a threat in attack, with Giles and Luke Morgan prominent, but they were denied by penalties at breakdowns.
Morris’s burst from inside his own half and Giles’ intervention set up the phase from which the flyhalf’s cross-kick found Morgan for the wing to go over. It was a great team effort.
The response that allowed Notshe to arrive was the pack power of the sharks.
Morris responded with a drive from close range, but Walsh was unable to convert from the touchline due to the whirling wind.
Sharks went for the line-out when awarded a penalty under Ospreys’ posts after Bosch’s long-range penalty attempt went wide.
Bosch broke through for the decisive late try, which he also converted, and that risk paid off.
Bosch once more added the extras after Venter powered over to seal the victory.
