Sisters Genny and Ellie Porter starred as Oxfordshire's women bounced back from heavy defeats against Devon and Dorset to beat the Royal Navy by 112 runs.

This was a fine win at the United Services Ground, Portsmouth, with Genny Porter scoring her maiden Oxon century and younger sister Ellie taking 5-6.

Genny's 113 not out came off 103 balls, including 13 fours and a six over square leg, as Oxon made 189-7 in their 40 overs.

This was the first time an Oxfordshire woman had passed 50, while Gemma Muttitt (18) and Bridget Rhodes-Moore (17) offered good support.

In reply, the Navy struggled to cope with the off-spin of Rhodes-Moore (1-10) and the leg-spin of Vicky Strode (1-13).

But it was Ellie Porter's leg spin that finished off the tail with aplomb, bowling all five of her victims.
