Edinburgh rues missed chances
Newport boss Justin Edinburgh refused to blame his side's midweek Capital One Cup exertions for County's loss to Northampton.
Jacob Blyth marked his Northampton debut with the opening goal as the hosts won 3-1 at Sixfields.
Signed on loan from Leicester only 24 hours earlier, the young striker gave the Cobblers the early lead which Roy O'Donovan doubled in the first half.
Gary Deegan added a third goal late on before substitute Connor Washington grabbed a late consolation for Newport.
The Exiles marked their return to the Football League after a 25-year absence by beating Accrington 4-1 last weekend and followed it up with an impressive Capital One Cup win at Brighton on Tuesday night.
Edinburgh said: "The scoreline was very harsh on us and anyone here could see that we gave a good account of ourselves. We don't like to lose but we weren't ruthless enough in the box.
"Extra-time at Brighton didn't take that much out of us and the players didn't look jaded. Their keeper was man of the match but in all fairness we gave him the opportunity to make the saves.
"The performance was good and we put Northampton on the back foot for long periods. But we had a 10-minute spell in the first half when we lost our way a bit. There were chances here to get goals and we just haven't taken them.
"We started really well but if you don't take your chances you must make sure you don't give easy chances away. I'm disappointed with the goals we conceded but it's a learning curve for us.
"If we continue to play like that we'll pick up more points than we lose. I'm sure we're capable of competing in this division."
