Sussex dent Yorkshire's hopes
Sussex 209 for 8 (Thornely 49) beat Yorkshire 200 for 9 by nine runs
Yorkshire's hopes of winning the Pro Arch Trophy were dented by Sussex who beat them by nine runs in the tournament's penultimate match.
Yorkshire need to beat UAE in the final match to finish level on points with Lancashire and Somerset, and they need a comprehensive win to overtake their Roses rivals.
Sussex got off to a good start, reaching 110 for 1 before losing three wickets without addition. The middle order rallied to boost them to 209 for 8, seemingly a below-par score in the conditions.
Yorkshire also started well before losing their way, 19-year-old Will Beer taking two quick wickets and thereafter the innings fell away.
