LV County Championship - Division One
Yorkshire 403 (A Shahzad 88, D J Wainwright 85 no, A W Gale 60, A Lyth 50, P P Chawla 4-115) & 284 (J A Rudolph 70, P P Chawla 5-112) v Sussex 448 (R J Hamilton-Brown 171 no, M W Goodwin 63, M H Yardy 58, D J Wainwright 5-134, A Shahzad 4-84) & 83 (D J Wainwright 4-12, M J Hoggard 4-29)
Yorkshire (20pts) beat Sussex (7pts) by 156 runs
Sussex were bowled out for 83, including a Matthew Hoggard hat-trick, as Yorkshire claimed a 156-run victory at Hove to move to the brink of Division One survival.
Hoggard, who took a hat-trick for England against West Indies at Bridgetown in 2004, accounted for Piyush Chawla, Dwayne Smith and Andrew Hodd with consecutive deliveries as the Tykes triumphed on a thrilling final day.
Sussex's capitulation in 25.3 overs leaves them as strong favourites to join Worcestershire in being relegated from Division One heading into the final round of matches.
Michael Yardy's men now sit 15 points adrift of seventh-placed Lancashire, while it remains mathematically possible that Hampshire and Yorkshire - in fifth and sixth respectively - could still be relegated.
On the final day, Yorkshire extended their second innings from a starting point of 147-2 to 284 all out by late afternoon, leaving Sussex a victory target of 240 in 40 overs.
Indian leg-spinner Chawla bagged 5-112 to finish with match figures of 9-227.
Sussex's run chase initially appeared on course as a breezy opening stand of 37 in 5.3 overs between Chris Nash (20) and Joe Gatting (26) got them ahead of the required rate.
But Gatting's departure in the sixth over, caught at midwicket off Hoggard, prompted a spectacular collapse that saw all 10 wickets tumble for 46 runs in the space of 20 overs.
Hoggard (4-29) was the headline act, running out in-form Rory Hamilton-Brown with an accurate throw from third man before his hat-trick hastened Sussex's demise.
He was well supported by left-arm spinner David Wainwright, who took 4-12 including the final two wickets.
Rory Hamilton-Brown's unbeaten 171 revived Sussex's hopes of avoiding relegation from the LV County Championship at Hove.
The 22-year-old notched his maiden championship century in the match against Yorkshire as the hosts closed their first innings on 448 runs ahead - a lead of 45.
It could have been so much more, but for the fact Sussex lost their last five wickets for just 56 runs and the visitors then made a strong start to their second innings by closing on 147-2.
Hamilton-Brown resumed on 32 and extended his fifth-wicket stand with Murray Goodwin to 128 in 32 overs before Goodwin was bowled off his legs sweeping at Wainwright after making 68, his highest score of the season at Hove.
Andrew Hodd then helped Hamilton-Brown put on 99 in 23 overs either side of lunch but Yorkshire fought back well in the afternoon.
Hodd was well taken to his right by Jacques Rudolph at slip and in a fiery spell down the slope Ajmal Shahzad then picked up his fourth wicket when Dwayne Smith checked a drive and was caught and bowled.
When Piyush Chawla edged to slip off David Wainwright, Sussex had lost three wickets in five overs but number 10 Corey Collymore gave Hamilton-Brown decent support in a stand of 28 before Wainwright took two wickets in three balls to remove Collymore and Jason Lewry and claim his maiden Championship 'five-for'.
Hamilton-Brown departed to a standing ovation, his runs having come off 210 balls. It was also the highest score by a Sussex batsman at Hove this season.
Yorkshire quickly reclaimed the lead, however, seeing Joe Sayers pass 1,000 runs for the season for the first time before being caught behind during an excellent spell of bowling by Collymore.
Adam Lyth, dropped on three at short leg, was bowled around his legs for 31 but South African opener Rudolph passed 50 for the ninth time in the championship this season and Yorkshire will begin the final day with a lead of 102.
Sussex made good progress in reply to Yorkshire's 403 at Hove in a match that could decide who joins Worcestershire in being relegated from LV County Championship Division One.
The hosts' top four all made starts and Murray Goodwin remained unbeaten on 44 as Sussex reached stumps on day two at 233-4, still 170 runs behind.
Goodwin, batting at number four, shared an unbroken 68-run, fifth-wicket stand with Rory Hamilton-Brown (32no) after Michael Yardy (58), Chris Nash (42) and Joe Gatting (46) had all failed to cash in.
Earlier in the day, Yorkshire advanced their first innings from 274-7 to 403 all out with Ajmal Shahzad and David Wainwright both falling within sight of centuries.
The eighth-wicket pair took their partnership to 157 before Shahzad was trapped lbw by off-spinner Hamilton-Brown (2-49) for a career-best 88.
Wainwright, who has two first-class hundreds to his name, was left stranded on 85.
Sussex leg-spinner Piyush Chawla took four wickets as Yorkshire battled to 274-7 at the close on day one of the Division One relegation clash at Hove.
Yorkshire started the day four points clear of their rivals and opted to bat first having won the toss, but they failed to push home their advantage on what proved a slow track.
Sussex made the ideal start when Yorkshire's leading scorer in the County Championship, Jacques Rudolph, departed to the third ball of the day for a duck - trapped leg before by Jason Lewry.
Chawla was into the attack by the 15th over of the day and had a wicket in his second as he had Joe Sayers stumped attempting a big shot.
Adam Lyth hit ten fours on the way to his second half-century of the season before being adjudged leg before off the bowling of Corey Collymore and Chawla then chipped in with two quick wickets before lunch to leave the visitors in trouble.
Yorkshire skipper Anthony McGrath propped forward to a leg break and tickled behind to wicketkeeper Andrew Hodd, while Jonathan Bairstow failed to read a Chawla googly and perished lbw for a 16-ball duck.
Andrew Gale and Gerard Brophy steadied the ship with a valuable sixth-wicket stand of 60, but Chawla was the man to break it as he bowled Brophy for his fourth scalp.
Gale eventually fell for 60 to the off-breaks of Rory Hamilton-Brown, but Ajmal Shahzad and David Wainwright added an unbeaten 65 to see Yorkshire through to the close in decent shape.
