Sussex suffered an 87-run defeat as Hampshire opened their Royal London Cup campaign with victory at the Ageas Bowl thanks to James Vince’s first century of the summer.

Vince, who made his international bow for England in the washed-out match with Ireland in May, laid the foundations with an 89-ball knock of 103, which included 12 fours.

Liam Dawson then starred with the bat and ball - scoring an unbeaten 73 and returning figures of 6-47 - to help Hampshire keep Sussex in check as the home side successfully defended an Ageas Bowl high 343.

Matt Machan made 93 for Sussex while Luke Wright hit 58 but once they perished Hampshire mopped up the rest of the wickets as the visitors were dismissed for 256.
