Newtown suffered their second defeat in four days after losing 2-0 at unbeaten The New Saints in the JD Cymru Premier.
Following a goalless first half, TNS took the lead three minutes after the break through Dean Ebbe who got onto the end of a corner.
The second followed 12 minutes later when Ebbe intercepted a poor Newtown back pass to round keeper Dave Jones and slot the ball home.
Next up for the Robins is a home match with Barry Town on Saturday afternoon.
