Lucas Barrios scored two early goals as Borussia Dortmund eased past defending champions Wolfsburg at the Bundesliga on Sunday.

Dortmund went three goals up in the first half before winning 3-1 at Wolfsburg to extend its undefeated run to nine games.

Juergen Klopp's team jumped to sixth place in the standings with 27 points from 16 matches with its sixth victory in the nine-game stretch.

Barrios was twice set up by Mohamed Zidan in scoring in the eighth and 10th minutes. And Patrick Owomoyela made it 3-0 after 37 minutes.

Grafite pulled a goal back in the 55th but Wolfsburg, who have not won in four games, never looked like getting anything from the game.

Wolfsburg have dropped to ninth place with just 23 points from 16 games.

Stuttgart conceded a late penalty to draw with Mainz, while Mainz maintained its unbeaten home record thanks to a late penalty.

The early game Sunday saw Mainz draw level with a 90th minute penalty after Stuttgart keeper Jens Lehmann was red-carded with two minutes left for stepping on the foot of Mainz striker Aristide Bance.

Eugen Polanski converted the penalty, which equalized Pavel Pogrebnyak's 11th minute goal for Stuttgart, who have failed to win in their last nine Bundesliga games.

Russian international Pogrebnyak, who also scored in Stuttgart's win over Unirea Urziceni to enable the team to reach the knockout stages of the Champions League, scored with his knee after Arthur Boka crossed the ball into the box.

It was the first game for new coach Stuttgart coach Christian Gross, who replaced Markus Babbel.

Stuttgart now have just 13 points and are languishing in 15th place, just above the relegation zone.
