1 - 2
Clapton claimed the local bragging rights with derby success at the Terrence McMillan Stadium.
The win represented only a second success in 12 matches for Chris Wood’s side, who had lost a Gordon Brasted Trophy tie at Eton Manor in midweek.
And it came after two early goals put them in control, with Tom Jeffes opening the scoring on three minutes and Ike Nzurba doubling the advantage on 16 minutes.
Daniel Felix replied for APSA, who had beaten Ilford less than 48 hours earlier, with a quarter of an hour remaining but it proved only a consolation as the understrength Tons took the points and completed a double over their rivals to keep a fine season going.
