A bad day for Hampshire ended with them flirting with first division relegation after rain frustrated their attempt to beat Sussex at Hove.Only 21 overs were possible on the final day at the 1st Central County Ground and between the showers Sussex, who needed 278 to win, reached 84 for 3 before a final downpour at 4pm ended play with opener Tom Haines unbeaten on 40. Both teams took 11 points.That at least covered the eight points Hampshire had been deducted earlier in the day for preparing a poor pitch when Sussex won at the Utilita Bowl in May.Hampshire have a trip to Somerset next week before they finish the season at home to title-chasing Surrey.Having been up against it after two days, Sussex will be relieved with an outcome which stretches the gap between them and the bottom two. They host ninth-placed Yorkshire next week before finishing the season against the side currently bottom, Worcestershire, at New Road.After the entire third day was washed out, more rain delayed the start until 2pm, leaving Sussex 51 overs to score a further 241 at 4.7 runs per over.On a pitch which was becoming more comfortable to bat on, Hampshire needed to take every opportunity going but in the third over of the day wicketkeeper Ben Brown put down a chance low to his right offered by night watcher Sean Hunt off Kyle Abbott. In the next over Hunt edged Keith Barker between second and third slips.Just 27 minutes were possible before another shower drove the players off with six overs lost but Hampshire then struck twice in successive overs to give themselves hope. Hunt had done his job, using up 61 balls in making 19 before left-arm spinner Bjorn Fortuin pinned him lbw half forward.In the next over Barker picked up a deserved wicket when Ollie Carter was bowled by a delivery which nipped back onto his off stump. But only 8.4 overs more were bowled either side of tea before another downpour was quickly followed by handshakes on the dressing-room balcony.
