After play had been delayed by rain until 2.30pm, Azharullah soon make inroads when he bowled Ed Joyce off his pads in the tenth over for 10.
Azharullah then struck with successive balls in his next over. Luke Wells (5) was caught low down by wicketkeeper David Murphy and Harry Finch, playing his first Championship game of the was leg before to an inswinger.
Nash reached a 53-ball half-century before losing skipper Luke Wright, who was making his first Championship appearance of season, when Azharullah switched ends and got some late movement to defeat Wright’s defensive stroke for 14.
That made Sussex 87-4, but Nash had moved to 71 at tea with Matt Machan, who was dropped on 5 by Alex Wakely at slip, unbeaten on 24, with Sussex 127-4.
