The first points did follow soon after but surprisingly resulted from a Bath penalty after they chose to take a quick tap but lost the ball forwards. Prop Andrew Millward did well to pick up the loose ball and offload to debut making wing Aled Brew.

Bath began to dominate possession and territory and were only denied their first points by strong defence from the Ospreys. An interception by centre Elvis Seveali'i could have resulted in a breakaway try but the referee called play back for an earlier offence.
