Northampton climbed back into the Premiership's top four after coming from behind to beat London Welsh in a scrappy game at Franklin's Gardens.
Welsh went ahead through a penalty try in the seventh minute and Gordon Ross's three points extended their lead, after Ryan Lamb's drop-goal.
Saints won a penalty try themselves, and Ken Pisi's converted score gave the hosts a seven-point half-time lead.
Lamb and Ross played out a kicking duel as Welsh ensured a losing bonus point.
VIEWS FROM THE DRESSING ROOM
Northampton Saints coach Dorian West told BBC Radio Northampton:
"They've got a big pack of forwards who are good in a lot of areas. We didn't get a chance to run them around and tire them out, like we usually want to, and they were able to stick in the game for long periods.
"We were a bit ill-disciplined at the start of the game, which was disappointing. Once they've got momentum, they're hard to stop.
"London Welsh are a pretty basic team but they've got a lot of spirit and they work hard for each other. A few sides have underestimated them this year and paid the price.
"I think Ryan Lamb has been pretty good in the last two weeks. Everybody makes the odd mistake. Today, a lot of his tactical work was really good."
London Welsh director of rugby Lyn Jones:
"We are really pleased. We came here looking to leave with something.
"I was pleased with the attitude and the boys' approach to the game.
"Northampton have a huge reputation at set-piece time and we took them on there today.
"We just lost the kicking battle, but we stuck in there and I think we deserved a point.
"We will grow in confidence from this performance and you could argue we had the better of their pack today."
