Sussex's bowlers impressed on the second day of their final pre-season friendly against Hampshire, which ended in a draw.
Ari Karvelas reduced Hampshire to 9-2 with two wickets in his second over.
When Sean Hunt removed James Vince and Ben Brown in the 18th over, Hampshire were under pressure at 48-5.
But a 77-run stand for the sixth wicket saw Hampshire close on 150-8.
The home side had earlier posted 163-6 in their first innings, with Oli Carter top-scoring with 35.
With rain preventing play on the opening day, it was agreed that each side would bat for a maximum of 45 overs, with Sussex getting first use of the Hove pitch.
Sussex got off to a difficult start when Tom Clark, centurion against Surrey earlier in the week, edged to Liam Dawson at second slip with the third ball of the day, bowled by former South Africa international Kyle Abbott.
Tom Alsop and Tom Haines had begun to rebuild Sussex's innings before the fluent Haines (26) lost his off stump to a Brad Wheal beauty in the tenth over.
Alsop brought up Sussex's 50 in the 15th over with consecutive boundaries off Hampshire youngster Eddie Jack.
But he was out for 31 soon after, chipping one to Nick Gubbins at mid-wicket off the bowling of Dawson with Sussex on 75-3.
Sussex's 100 came in the 27th over when Oli Carter played Dom Kelly to the cover boundary for a single.
But Carter was out in the next over, top edging a sweep from Dawson to Jack, who took an easy catch.
Dawson had his third when he had James Coles caught behind for 21 in the 34th over with the score on 125.
That brought Fynn Hudson-Prentice, Sussex's leading run scorer in the County Championship last season, to the crease to join John Simpson, who looked busy before he was caught and bowled by Dawson for 18.
Hudson-Prentice (25) and Danial Ibrahim (2) negotiated the final five overs of the innings, putting on 25 for the seventh wicket as Sussex closed on 163-6.
England seamer Ollie Robinson thought he had Ali Orr lbw in the first over of the second innings, but the nick bounced just in front of the second slip.
The former Sussex batsman didn't last long, however, as he was caught behind off the bowling of Simpson for just two off the bowling of Karvelas.
Two balls later, Karvelas had his second. This time he found the edge of Hampshire skipper Gubbins (0) to give Simpson another easy catch.
Simpson had his third victim in the ninth over when Fletcha Middleton was run out by Robinson for four. Hampshire was three wickets down with just 15 on the board.
Vince then decided to counterattack and hit Karvelas for four fours in the tenth over.
Vince and Brown put on 32 for the fourth wicket before Vince edged Hunt to Clark at second slip for 30.
Brown (7) fell in the same over, pulling a short delivery to the waiting Henry Crocombe at mid-wicket, as Hampshire struggled at 48-5 in the 18th over.
Hampshire made a good recovery through Dawson and Tom Prest to reach 125 before Sussex finally broke the partnership. Dawson (49) gifted Carter a catch at cover off Coles.
Abbott was the next man out in the 38th over when he was struck on the pad by Coles at mid-off.
Prest (36) then chipped a tame shot to Crocombe at mid-off to give the impressive Coles his third wicket and leave Hampshire on 142 for eight.
Toby Albert (7) and Joe Weatherley (2) ensured that Hampshire finished the match on eight, with Haines bowling the final over.
Sussex returns to The 1st Central County Ground on Friday (April 5) to begin their County Championship Division Two campaign against Northamptonshire.
