BOWERS were good value for their win as a Calvin Poku brace gave them revenge for an FA Cup defeat to Eton Manor in August.
In a tight and cagey first half both teams failed to both teams struggled to create chances.
Bradley Warner forced Manor's Sam Tanner in to a fine save and Bowers keeper Micheal Doyle made a finger tip save from John Bricknell's close-range header.
The deadlock was finally broken in the 67th minute when Poku sprang the offside trap to run through and slot coolly past the advancing Tanner.
And within six minutes he had doubled the lead from the penalty spot after Warner was pulled down in the penalty area.
Poku, Callum Leahy and Georgie Shelvey all went close for Bowers late on, but could not add to the total as the game finished 2-0.
Bowers are back in league action tonight, away to Barkingside.
