The Saints suffered another defeat on Saturday as they went down 3-1 against promotion chasing Havant & Waterlooville at Clarence Park.
Havant started the game the brighter of the two sides and took the lead through Ayunga, who pounced at the near post following a corner to turn the ball home.
The visitors continued to cause City problems and Dean Snedker had to be at his best to deny Tarbuck.
The Hawks doubled their lead a minute before the break, however it was in controversial circumstances.
Following another set-piece, the ball fell into the path of Kedwell and the forward went down under pressure from Diedhiou. The referee appeared to start to indicate that was simulation until he changed his decision and pointed to the spot. Kedwell stepped up and sent the penalty low to Snedker’s right.
Ian Allinson’s men returned to the pitch following the interval looking much improved.
Albert Adu almost reduced the deficit when he latched onto a Banton through ball, but saw his low driven effort well saved by Worner.
The Saints finally found a breakthrough in the 58th minute through Scott Shulton, who was in the right place to turn home Sprague’s low delivery from close range.
Sprague continued to cause issues down the left and tested Worner with a drive that stung the palms of the goalkeeper.
Havant, however, put the game beyond doubt eleven minutes later.
Kedwell did well to work the ball down the right, crossed it in towards Ayunga, and the forward slotted it past the stranded Snedker.
City were presented with a golden opportunity with five minutes left on the clock after the referee awarded a penalty following a clumsy challenge on Musonda.
Josh Oyinsan stepped up and saw his initial spot-kick saved. The ball ricocheted into the path of Georgiou but Worner scrambled across and made the stop, before Oyinsan had his follow-up blocked on the line by a combination of two defenders.
The Saints are back in action on Tuesday night against Bishop’s Stortford in the Herts Senior Cup before they have a Saturday off.
