Sussex strengthened their County Championship challenge with an eight-wicket win over Middlesex with four sessions to spare at Hove.
The hosts knocked off their victory target of 95 runs in 25.3 overs, after dismissing Middlesex for 211 in their second innings,
A fourth successive home win has lifted them above Nottinghamshire into second place, 11 points behind leaders Warwickshire.
Warwickshire remain title favourites but they still have to play Nottinghamshire twice and Sussex are poised to cash in should the leaders falter.
The wicket continued to give plenty of assistance to bowlers prepared to bend their backs, with the ball lifting alarmingly on several occasions.
Middlesex's hopes of setting a bigger target had been undone by a hostile burst before lunch from Amjad Khan, who took three wickets to finish with eight wickets for 64 runs - his best match figures for Sussex.
After Steve Magoffin had removed nightwatchman Toby Roland-Jones (20), Amjad broke the back of the innings with three wickets in four overs.
Sam Robson, who had faced 138 balls for his 36, was squared up by a beauty of a delivery from Amjad which he edged behind, then John Simpson was well held at slip by Mike Yardy as he pushed forward.
Gareth Berg was his third victim after an ill-advised waft outside off stump and Sussex picked up their fifth wicket of the session when Chris Nash anticipated Dawid Malan's paddle sweep and ran across from short leg to take a juggling catch.
Neil Dexter batted solidly for 40 but after lunch he became one of three victims in 13 balls for James Anyon which finished off the innings.
Ollie Rayner, having just been struck on the back of the helmet, was caught behind as he backed away and Dexter's 93-minute vigil ended tamely with a waft down the leg-side.
Anyon then wrapped up the innings by bowling Tim Murtagh - having had him caught at third man off the previous delivery only to be called for overstepping.
Wicketkeeper Ben Brown's six catches in the innings equalled the county record and was the 11th time it had happened in Sussex's history. Ironically, Sussex's oldest surviving player Rupert Webb - who achieved it in 1955 and 1960 - was at the ground celebrating his 90th birthday.
Sussex lost opener Chris Nash in the fifth over of their victory chase but skipper Ed Joyce and Luke Wells teamed up to take them to within 27 runs of victory.
Although Joyce was superbly caught off his own bowling by Rayner, victory was wrapped up 15 minutes after tea as Murray Goodwin passed 22,000 career runs in his unbeaten 19.
