Mark McGhee admits it is really starting to get serious in the build-up to Championship action.

The Seagulls' manager saw his men weather a spirited Lewes challenge in searing heat yesterday to score their second win of pre-season.

Albion have just one more run out left against non-league opposition, at Bognor on Wednesday night, before they step up a level by taking on a trio of Coca-Cola League clubs.

McGhee is gently phasing out his policy of limiting players to 45 minutes in games. Kerry Mayo, as at St Albans on Friday, had 90 minutes yesterday and Guy Butters also played a full game.

By contrast Albert Jarrett, who failed to make the most of some promising situations on the left, was taken off after half an hour.

The premature withdrawal of Jason Dodd need not cause any alarms. McGhee reported his rightback felt soreness in a thigh muscle which has been troubling him and left the action as a precautionary measure.

McGhee now plans for another key week in the build-up to the season-opener at Derby on August 6 .

He said: "We'll probably cut down to one session a day now because of the heat.

"We're reducing the running distances. We're down to 100s and 50s and we've got another game on Wednesday night. Then we go into the three more serious games of our build-up.

"It will only be when we go to Colchester, Oxford and Bournemouth that we will really start to play people for 90 minutes.

"But don't read too much into that.

"The team that will play against Derby has still to be sorted. Whoever runs out against Colchester next Saturday can't start thinking 'that's what he thinks the team's going to be'.

"There are still people to prove themselves and we still hope to bring in a couple."

Trinidadian defender Brent Sancho and Argentinian striker Federico Turienzo, both on trial, got their chance for 56 minutes yesterday.

Sancho looked strong, solid and reliable with the ball, and Albion will continue to learn what he can do when he trains with them this week.

Turienzo worked hard and was keen to impress but it was hard to see what he offered the Seagulls that they do not possess already.

As if to prove a point, three of McGhee's current strikers all hit the target.

Colin Kazim-Richards continues to do his chances of first team action no harm.

He had already powered a 25-yard drive just over and bustled effectively when his own hard work and strength won a penalty just before the break.

His efforts in protecting the ball inside Lewes's area and making room to cross proved too much for defender Max Ellison-Hustwick, who tugged his man back by the shirt.

Kazim-Richards took the spot kick himself and rifled it confidently into the top corner.

That added to the lead given Albion when Dean Hammond, who was effective on the left of midfield, powered in a 14th-minute header from a corner.

Referee Paul Melins did his best to keep things from over-heating, ordering cricket-style drinks intervals for the players midway through each half and advising Lewes to substitute Kirk Watts after he felled Dean Cox off the ball.

Just a minute after that enforced switch, the Rooks were back in the game as Carl Beckford's shot hit Paul Reid on the line and flew in off Adam El-Abd, who had just come on.

That was the start of a good period for Lewes, who played some nice stuff at times, could put a foot in when they saw fit and had pace in attack.

The equaliser they deserved came when Jean-Michel Sigere swept home a low cross 19 minutes from time.

Albion, though, finished the game strongly and went back ahead three minutes from time.

The versatile Reid, now operating in central midfield, guided a precise pass through the inside right channel and Robinson eased past oncoming goalkeeper Paul Wilkerson before finishing from an angle.

That goal will have done Robinson good, as he had missed a couple of great chances in previous games. So too had McCammon, so he will have enjoyed his precise finish just a minute after Robinson's goal.
