Next up: Hampshire. And for Paul Farbrace's side a victory would be most welcome following back-to-back defeats that have sent the Sharks to the bottom of the Vitality Blast South Group after three rounds of matches.
Farbrace admitted that his side "got what they deserved" on Saturday night following defeat to then-bottom side Middlesex, losing by a margin of 31 runs that saw Tom Clark hobble off with injury when in the field.
He still batted, and batted well, with Jack Carson as his runner as the Sharks set out to chase a hefty target of 214, and indeed it was to be a target too far out of reach as Sussex came up short despite explosive - albeit somewhat short - knocks by Tom Alsop and James Coles.
Coupled with a difficult defeat at Kent the Monday prior, the stakes are now just a bit higher as in-form Hampshire is the next destination on Tuesday evening.
Team News
Paul Farbrace has named a 14-player squad for the trip to Southampton, with Henry Crocombe returning, following his impressive stint with England Lions, where he took 4-65. Tom Clark misses out having picked up an injury during Saturday night's defeat to Middlesex.
Men's Squad: Alsop, Briggs, Carson, Carter, Coles, Crocombe, Hudson-Prentice, Hughes, Lamb, Leaning, Mills (c), Price, Simpson (wk), Ward
The Opposition
Hampshire have made a positive start to this year's Vitality Blast, winning three of their opening four matches.
They arrive on a three-game win streak, too, having comfortably beaten Essex and Surrey at home before recording victory again on Sunday at Middlesex's Merchant Taylors' School.
Runs have been fairly shared around amongst the batting cohort, with South African overseas Tristan Stubbs making a positive start. The irrepressible James Vince and experienced Liam Dawson have added runs, too.
And with the ball it's been mostly Scott Currie - brother of Sussex Shark, Brad - who has been most effective, taking nine wickets from the opening four matches at an average of 9.33.
Previous Encounters
This will be the 42nd meeting between the Sharks and the Hawks in T20 cricket, as Sussex look for win #18 against their neighbours in the competition.
Hampshire arrive into this matchup having won 21 of those 41 meetings, and are in good form over the Sharks having completed a Blast double last season.
