The Ospreys bagged three tries against Zebre coming away from Italy with a 34-16 victory.
Dan Biggar was the Ospreys' star with the fly-half claiming 24 points. He opened the proceedings with a sixth-minute penalty and, after Gonzalo Garcia had levelled, he pushed his side out to 9-3 with two more three-pointers.
Zebre's Alberto Chillon was then sent to the sin-bin and Richard Fussell made the most of his absence by grabbing his side's first try.
Biggar converted and, when Jonathan Thomas went in as well, the Ospreys led 21-6 at the break, with Daniel Halangahu scoring a penalty on the whistle. Luca Redolfini then touched down (43) and when Halangahu converted it was 21-13, before he and Biggar traded penalties.
The Welsh international would have the last word, though, scoring a fifth penalty before converting his own try inside the last quarter.
