RB Leipzig climbed to third in the Bundesliga on Sunday night thanks to a 1-0 win at Wolfsburg which extends their record-breaking unbeaten start to their maiden top-flight season to seven matches.
Emil Forsberg wasted the best chance of the first half when he sent a penalty well wide of Koen Casteels' goal, letting the Wolfsburg keeper off the hook after his foul gave the visitors an 18th-minute spot kick.
Forsberg did put the visitors in front with 20 minutes left, shifting the ball onto his preferred right foot before sending a shot into the far corner of Casteels' goal from the edge of the penalty area.
Wolfsburg could not find an answer and, with their fourth blank of the season and their third at home, they succumbed to a defeat which will turn up the heat on coach Dieter Hecking with his side in 14th, just two points above the bottom three.
Pablo de Blasis and Yunus Malli were on target as Mainz beat local rivals Darmstadt 2-1 to move up to seventh in the Bundesliga.
Mainz took the lead in the fifth minute when De Blasis turned in Gaetan Bussmann's pass to finish off an excellent team move.
Jhon Cordoba missed several chances to double the lead, hitting the crossbar with one header, before Antonio Colak wasted the chance to level for Darmstadt on the stroke of half-time when his penalty was saved by Jonas Lossl.
Mainz doubled their advantage with a penalty of their own, dispatched by Malli in the 56th minute, before Jerome Gondorf pulled one back for the visitors, converting a stoppage-time penalty, but it was too late for Darmstadt.
