Timothy Chandler's early goal was enough for Nurnberg to snap their eight-game winless streak with a victory at home to Kaiserslautern.
Chandler scored the only goal of the game in the 14th minute to move Nurnberg onto 15 points in the Bundesliga, while Lautern have 13 points after failing to win for the fourth straight game.
The first chance of the game resulted in the opening goal after 14 minutes. It came from a defensive blunder by Kaiserslautern defender Alexander Bugera, who lost the ball to Chandler on the right side. The American turned inside and blasted a left-footed shot past goalkeeper Kevin Trapp from the edge of the area.
Nurnberg were close to doubling their advantage after 33 minutes with Chandler passing to Tomas Pekhart, whose cheeky effort went into the side-netting.
The visitors finally carved out a chance in the 38th minute but Oliver Kirch's long-distance effort went just wide of the left-hand upright.
Kaiserslautern were lucky to still be in the game just a minute after the re-start when Pekhart's cross clipped off defender Mathias Abel and then struck the left-hand post before being gathered up by a relieved Trapp.
Nurnberg came close to adding a second on the hour mark but Christian Eigler volleyed Chandler's centre over the bar.
The hosts' defence was excellent in the second half without allowing a single chance for Lautern, and were more than good value for the three points at the whistle.
