City recorded their fifth win of the summer thanks to a comprehensive performance against 2019/20 National League South champions Wealdstone at Clarence Park on Tuesday evening.
The visitors started sharply but the Saints quickly grew into the game and went close when Jeffers saw his cross nodded just over his own bar by a Wealdstone defender.
The deadlock was broken with twenty-five minutes on the clock.
Devante Stanley and Munashe Sundire combined down the right and the midfielder was able to deliver a low cross that beat everyone and eventually fell to Zane Banton, who made no mistake with a rifled strike.
City doubled their lead less than two minutes later as Sundire turned goalscorer. The 23 year-old latched onto a through ball and powered into the area before smartly finding the far corner of the net.
Shaun Jeffers added his sixth of pre-season from the penalty-spot after he was brought down in the 41st minute. The forward made no mistake as he sent the spot-kick low to the goalkeeper’s right.
The Saints continued in a similar vein after the interval and Kyran Wiltshire added a fourth and final goal with an impressive solo-strike. The midfielder picked the ball up outside the box and danced past a defender before firing high into the roof of the net.
A rare Weladstone attack on the hour mark ended with the visitors being awarded a spot-kick following a challenge by Tom Bender. Experienced striker Ross Lafayette stepped up and saw his penalty tipped wide of the post by City stopper Michael Johnson.
Both Banton and substitute Chidyausiku then saw optimistic efforts well saved by the Wealdstone goalkeeper.
Wealdstone came close to reducing the deficit with five minutes left, but Charlee Hughes could only manage to find the side-netting while under pressure from Jack de Groot.
The Saints are back in action behind closed doors on Saturday when Sutton United are the visitors to Clarence Park.
