Ed Joyce and Matt Machan both made hundreds as Sussex got their Clydesdale Bank 40 campaign off to a winning start with a crushing 144-run victory over the Unicorns in Group C at Hove.
Sussex's total of 291 for three on a dry, slow pitch was always going to prove too much, especially after Unicorns' openers Michael Thornely and James Ord were dismissed in the first four overs of the reply, and the visitors could only make 147 for nine.
The two left-handers shared a second-wicket stand of 175 and although opener Joyce was out shortly after reaching his 11th one-day hundred 21-year-old Machan, who was playing only his third List A game for Sussex, pushed on to score an undefeated 126.
