Eastbourne Borough came within minutes of a point at Chelmsford City but left empty handed again thanks to an injury time strike from the hosts’ Jason Williams.
Borough, who have never won at the Melbourne stadium under boss Tommy Widdrington, found themselves behind after 17 minutes as Williams opened the scoring.
The Southend United loanee burst through the middle to slot a composed finish beyond the reach of Lewis Carey.
Borough wasted no time in responding, however. Dean Sinclair broke the offside trap and the midfielder ran through and stabbed the ball into the bottom corner past Bradley Watkins in the City goal.
Simon Johnson could have further punished the hosts for some slack defending when he pounced on Chelmsford captain Mark Hughes’ deflection.
He opted to shoot first-time but blazed over when he ought to have made the keeper work.
Tempers then flared a little after Michael Cheek was booked for an adjudged foul on Ian Simpemba. That resulted in the Boro captain giving the Clarets’ faithful a sarcastic thumps-up gesture as frustration from both camps began to momentarily overrule.
The two sides went in level at the break before Hughes seemingly arrived out of nowhere to head home at the back post after the ball somehow found its way across goal.
Rohdell Gordon soon came close to a third which could have put Borough to bed. But he flashed his shot wide after an unconvincing clearance by Ian Simpemba.
Watkins was then called upon up the other end to execute a fine, low save to keep City’s lead in tact as the visitor’s committed men forward, leaving their back-line exposed.
Darren Lok then had one of his first efforts of the game when he broke free of Yado Mambo, only to fire wide when off-balance as a Boro’ equaliser looked possible.
Possible then turned into reality when Substitute Nathan Pinney fired home after he beat Mambo for pace as the Clarets were pegged back for a second time.
Borough looked on course for a share of the spoils. But it wasn’t to be . Jason Williams fired the hosts in front once again in stoppage time when he latched onto a timely lay-off from centre-back Marvin Ekpiteta. Chelmsford move up to fifth, and the final play-off sppot, in the Vanarama South. Borough stay 11th.
