Nathan Paxton celebrated his 100th league appearance for Horndean with the match-winner against Bournemouth Poppies at Five Heads Park on Saturday.
Paxton struck the only goal of the Wessex League premier division game after 20 minutes – following good work from Mark Smith, who teed him up to score from close-range.
His strike ensured the Deans bounced back from their 2-1 defeat at the hands of struggling Totton & Eling last week.
And boss Dave Carter was delighted to claim a victory which extinguished any outside chance of being dragged into a relegation scrap.
‘It was nice to put three points on the board,’ said the manager.
‘And this win makes us mathematically safe now.
‘We had enough chances to put the game to bed much earlier.
‘When they came back at us in the final 15 minutes our keeper Tom Boyle pulled off some good saves.’
A tired and depleted AFC Portchester slipped to a 2-1 defeat at the hands of Salisbury-based hosts Bemerton Heath Harlequins.
The home side took a 25th-minute lead before Danny Thompson equalised on the stroke of half-time with a 25-yard free-kick.
Bemerton regained the lead at the start of the second half.
And the visitors lacked the energy to claw it back.
‘We were without six players due to illness and injury,’ said director of football Mick Jenkins.
‘That was our fourth game in seven days and it showed.
‘Their two goals, both headers from set-pieces, were disappointing and we could have dealt with them better.’
Moneyfields overcame a disastrous morning to win 4-2 at Totton & Eling.
The visitors, already without four key players, had two more drop out an hour before the game.
‘When we went 1-0 down I thought we were in for a tough afternoon of it,’ said Moneys manager Miles Rutherford.
‘Then the players responded well to get us the three points.’
Pabs N’Doye hit a double, while Connor Bailey and Bobby Scott got the others.
