Inigo Calderon's second half strike gave the league leaders three points against Notts County this evening.
Brighton presented arguably the toughest test of the season for the Magpies so far. The Seagulls, heading into the fixture, were unbeaten at home during 2010/11 and were on a run of five straight wins.
Paul Ince welcomed back Ricky Ravenhill, who had been sidelined with an ankle issue, as part of a five-man midfield. Dave Martin was handed a start on the left flank, following his return to action at the weekend, and Craig Westcarr was named on the bench.
The hosts had two great chances during the opening stages, with the first seeing striker Chris Wood chest Calderon's low cross wide of the near post. Wood then directed Elliott Bennett's free kick over the bar with his head.
Brighton continued to push forward in a confident manner and once again came close from a corner. Gary Dicker's whipped centre was met by the run of Glenn Murray, only his header was directed a few inches too high.
Murray came close again with a volley from 12 yards, which cleared the bar. However, Bennett was the first to test Nelson with a hit from range that forced the stopper to flick the ball over with his fingertips.
Alan Gow had Notts' first attempt, when he cut inside from the right wing and struck high and wide of Casper Ankergren's goal. County, as the match edged closer to the interval, were showing greater attacking intentions, having been pinned back for long periods.
Dave Martin almost sent Notts in at the break a goal to the good, when he tricked his way past three players on the left wing, but Ankergren parried his stern shot behind at the near post. Mike Edwards connected with the resulting corner but he didn't get enough power behind the ball to seriously threaten.
Notts came out after half time looking much more assured in possession and held a higher line, as they searched for an opener. Brighton struggled in their offenses, with the Magpies' midfielders working hard to shut them down early.
On 64 minutes, the Seagulls went ahead from their first real opportunity of the second half, when substitute Craig Noone got a cross in from the left by-line. His looping delivery was out of Nelson's reach and Calderon was able to poke home from close range.
A double change was made, as Notts looked to salvage a point. Njogu Demba-Nyren and Westcarr replaced Hughes and Ravenhill, setting up a 4-4-2 formation.
Gow and Demba both tested Ankergren with low strikes, as the game opened up in the dying stages. For the home team, Francisco Sandaza's powerful attempt was gripped by Nelson and Dicker dragged wide.
Martin fired wide, rounding off another promising run, during added time but it wasn't Notts' day, as Brighton secured their sixth set of three points on the bounce. Now a trip to Huddersfield awaits - another tough test for Ince's side.
