Borussia Dortmund remain on course for a new Bundesliga points record after thumping relegated Kaiserslautern at the Betzenberg.
The Westphalians are just one point short of the current record of 79 points with one game to go thanks to a hat-trick by Lucas Barrios and further goals by Mario Gotze and Ivan Perisic
An own goal from Felipe Santana gave the Red Devils the lead while Pierre de Wit scored Kaiserslautern's second in their final home game of the season.
Having clinched the title last weekend, now was the time for Dortmund coach Jurgen Klopp to experiment ahead of the DFB-Pokal final with Bayern Munich and he chose both Barrios and Robert Lewandowski in his starting XI.
There was also room for Germany international Gotze to make his first start of 2012 after recovering from a groin operation.
Kaiserslautern picked up their first win of 2012 last weekend and, despite already being condemned to relegation, they made a good start, taking the lead in the 16th minute.
Santana put Konstantinos Fourtinos' cross into his own goal as he raced back to try and clear the danger.
Kaiserslautern's lead lasted only two minutes, though, before Patrick Owomoyela sent in a cross which was met by Barrios to head in only his second goal of the season.
Goal number three for Dortmund's top goalscorer last season arrived eight minutes later when he was picked out by Perisic and had an easy task of scoring from close range.
Gotze got in on the act in the 33rd minute as the stars of 2011 helped the 2012 Bundesliga champions edge closer to a new points record.
Lewandowski was the provider as he pulled the ball back to the Germany international, who showed he has not lost any of his goalscoring instinct with a well-placed shot past Tobias Sippel.
De Wit reduced the arrears early in the second half with a header past Mitchell Langerak.
It took only six minutes for Dortmund to re-establish their two-goal lead, though, with Barrios completing his hat-trick thanks to a mistake by Sippel. Rather than clearing the ball, he let Perisic steal him of possession and square the ball for Barrios to score into an open goal.
Perisic completed the scoring in the 78th minute when he exchanged passes with Shinji Kagawa before curling his shot unstoppably into the far corner.
