Gomez brace earns Bayern win but Dortmund maintain lead

(CNN) -- Borussia Dortmund maintained their three-point lead over title rivals Bayern Munich with a comfortable 3-1 win against Wolfsburg in the Bundesliga on Saturday.

Dortmund went ahead in the 22nd minute thanks to a goal from Robert Lewandowski before Ilkay Gundogan made it 2-0 in the 49th minute.

Wolfsburg pulled one back in the 61st minute with a header from Mario Mandzukic and may have found a equalizer but for defender Alexander Madlung being sent off in the 84th minute.

Dortmund made the most of the numerical advantage as Lewandoswki bagged his second in injury time to make the game safe.

The win sets up the reigning champions for the visit of Bayern Munich to the Westfalenstadion on Wednesday in a fixture which will go a long way to deciding the destination of this year's title.

Bayern also won Saturday as Mario Gomez scored twice in a 2-1 victory over Augsburg.

The German striker was on target after just 24 seconds converting a cross from French international Frank Ribery.

Relegation-threatened Augsburg leveled the scores in the 23rd minute through Koo Ja-cheol, but Gomez was on hand for his second of the afternoon latching onto a pass from Dutch winger Arjen Robben in the 59th minute to claim his 25th goal of the season.

Stuttgart thrashed Mainz 4-1 to go fifth, eight points behind Borussia Moenchengladbach who host second-from bottom Hertha Berlin in the evening kick-off.
