Horsham posted 249 for six declared at Roffey with 67 from Tom Johnson and 32 from John Burroughs as Matt Davies took 3-46.
But then Josh Fleming made 98 and Chris Plaister 60 to take Roffey to a three wicket win at 252 for seven despite leg-spinner Michael Munday grabbing 5-73.
It was easy for Preston Nomads at home to Bexhill who they dismissed for just 106 in 41.5 overs as Carl Simon took 4-30 and Matt Hobden 3-34.
Nomads cruised to 109 for three in 29.2 overs with Stuart Faith 34 not out.
Darryl Rebetts has taken over the Worthing captaincy from Michael Gould and made his first ever League century, 101 not out, in his first game in charge but he still finished on the losing side.
Worthing made 247 for five declared with Stuart Carter (47 not out) sharing an unfinished sixth wicket stand of 106 with Rebbetts while Michael Gould made 31, Craig Fowle with 3-78 in 22 overs was the pick of the visitors’ bowling.
East Grinstead won the game by three wickets with two balls to spare as they posted 251 for seven.
Aussie Danny Irvine, in his first game in England, made 70 and teenager Nathan Bailey his his first ever League fifty as he was out for 90! For Worthing, still without a win since their promotion last year, Benn Challen took 4-64 in 18.4 overs.
