Haywards Heath were taken to extra time by brave East Grinstead before a 35-20 win kept them on course for a sixth successive Sussex Trophy success.

Heath now face a tricky looking trip to Bognor while Worthing, convincing winners at Uckfield, entertain either Eastbourne or Hastings & Bexhill in the semis.

Heath looked to be heading for a shock exit when they trailed 20-10 at half-time.

The home side kept some of their big guns on the bench in the first half and Grinstead took advantage, running in three tries through Paul Goodene, Guy Cook and Alex Ingham while Steve O'Reilly added a penalty and conversion.

Heath had gone in front through Andrew Cook's second minute chip and chase effort and winger Kevin McDonald's score reduced the arrears.

The hosts then made three half-time changes and they paid dividends when replacement Nick Killick went over following a line out in the first minute of the second period.

Owen Ashton converted and then took the game into extra time when he landed a penalty with five minutes to go.

Heath took control in extra time when their superior fitness helped them score further tries through Ashton and Dave Cook. Ashton also added a penalty and conversion.

Heath's Jon Graham said: "East Grinstead really played well for the first hour, but in the end our fitness made the difference.

"It was a bit of a scare for us, but when we made the changes we did at half-time we started to play a lot better."

Bognor skipper Tom Spurle was thrilled to be on the winning side for the first time in 11 years against Lewes.

"It's only the second time we've reached the semi-finals so we're delighted," he said. "Haywards Heath is the draw we didn't want, but we have home advantage so we'll be going for it."

Bognor did it the hard way on Sunday, coming from 11-3 down to win 20-14 thanks to a try in the last five minutes from Andy Shipp.

Steve Woolcombe's try and Shipp's penalty had reduced the early arrears to 11-10 by half-time, but Bognor left themselves with an uphill task when Colin Meads, who had already been sin-binned after a dust-up with Richard Siggs, was sent off for a high tackle.

Both sides exchanged penalties before Shipp's decisive touchdown which was improved by veteran Stuart Pearce.

Martin Lovell crossed for Lewes during their early dominance and Paul Livesey landed three penalties.

But injuries robbed them of skipper Dave Hemsley while fly half Huw James, so important to Lewes's passing game, was absent after discovering his car had been stolen on the morning of the match.

County call-ups and injuries meant neither Uckfield nor Worthing were at full strength, but it was the visitors who were always in control as they eased to a 41-5 victory.

A strong performance by the pack who won three scrums against the head provided the cornerstone for Worthing's success.

Another early try - this time after 42 seconds from flanker Alan Brace - gave them the perfect start and Steve Imrie and Paul Mills benefitted from rolling mauls as Worthing opened up a 19-0 half-time lead.

Brace, Ben Coulson, replacement Dave Davies and lock Paul Cox added second half tries with Coulson adding three conversions.

Uckfield's consolation score came from Tim Rowland.

Hastings face Eastbourne in the outstanding Trophy quarter-final on March 24 after chalking up their 17th successive victory against Crowborough.

They ran in nine tries in a convincing 58-13 victory with Steve Pepper and Seb Halligan scoring two apiece.

Skipper Paul Sandeman's 18 point haul included a try, penalty and five conversions while further scores came from Neil Redman, Mark Patmore and Rob Sparks.

Crowborough skipper Bruce Brooker kicked two penalties and converted their second half consolation try.
