Ross Lines celebrated his debut for Lavant first team with a brace of goals to keep the Chichester side in contention for promotion.
Coach David Parker found himself four key players short but the problems of last season in producing a reserve team paid off as he was able to draw on strength in depth.
There was no quarter given as both teams went hammer and tongs, leading to a series of bookings.
The home side started well but Worthing crept back into the game as the Lavant midfield failed to link with the forwards, leaving them isolated.
David Parker rectified this at half-time, urging the advanced midfielders forward and a striker to come short. This led to early Lavant pressure at the restart and the Chichester side were unlucky not to go ahead.
This advantage was put in jeopardy when Lavant’s Shane Rapley was sent off for a second bookable offence 9 minutes into the half. But ten man Lavant lifted their game even further.
It was then that former Hayling Island and Petersfield striker Lines harried centre back Elton and his keeper, winning the ball and running it into an empty net on 59 minutes.
Worthing threw everything bar the kitchen sink at the homeside but the 10 men held on to see substitute Joe Hepworth thread Lines through for his second on 72 minutes.
Court came off injured and Ben Thomas, the four goal hero of last week deputised as sweeper.
Worthing had a goal disallowed and a shot hooked off the line but Lavant, who have lost to the visitors in all of their last seven meetings held on to beat their Bogey team and secure all three valuable league points.
