Joyce stars with the bat in Sharks victory
Chris Nash blasted 35 off just 13 balls as Sussex beat Middlesex to secure a home tie against Warwickshire in the quarter-finals of the Twenty20 Cup.
Sussex were struggling in pursuit of Middlesex's total of 127-8 as they reached the halfway point at just 36-3.
A partnership of 55 between Dwayne Smith (33) and Ed Joyce (41no) got Sussex back on course before Nash hit 26 off the penultimate over from Chris Silverwood to seal victory with an over to spare.
Earlier, Yasir Arafat had been the pick of the Sussex bowlers with 2-13 from his four overs.
