County Championship D1, Hove (day two, close): Warwickshire194-8; Sussex 545 Warwickshire were left chasing a really enormous score after the home side went way past 500.
After Tony Cottey was finally out for 188, Matt Prior picked up the reins to smash exactly 100 from just 136 balls.
The hard-working Waqar Younis ended up with five wickets, but could have done with better support, although in perfect conditions it was clearly a bastman's day.
That, however, was until the visitors batted.
Mushtaq Ahmed's three wickets soon reduced Warwickshire to a desperately inferior score.
Michael Powell hit 60 at the top of the order, but the middle order caved in and Warwickshire will be surely be following on on Sunday.
Sussex: R R Montgomerie, M W Goodwin, P A Cottey, C J Adams (Capt), T R Ambrose, R S C Martin-Jenkins, M J Prior (Wkt), M J G Davis, Mushtaq Ahmed, R J Kirtley, J D Lewry.
Warwickshire: N V Knight, M J Powell (Capt), I R Bell, M A Wagh, I J L Trott, D R Brown, T Frost (Wkt), A Richardson, C O Obuya, M M Betts, Waqar Younis.
