Weston hit an match-winning 110 in the C&G Trophy final

The opener's unbeaten 110 at Lord's last August took the club to their sixth one-day crown in as many years.

"I am delighted to commit for the next three years to a club that is going in the right direction and look forward to continued success," said Weston, 31.

Chief executive Tom Richardson added: "Philip is a key player as we look to develop the squad further."
