A first half penalty converted by Dutchman Paul Verhaegh lifted FC Augsburg to seventh in the Bundesliga on Sunday with a 1-0 home win over Hertha Berlin.

Rightback Verhaegh hammered his spot kick into the left corner after 27 minutes after Hertha keeper Thomas Kraft had taken down Raul Bobadilla in the box.

It was all Augsburg needed to pick up their third win this season, pushing Markus Weinzierl's team to nine points, five off fellow Bavarians and leaders Bayern Munich.

Eintracht Frankfurt are playing at tailenders Hamburg later Sunday with a chance to move to nine points as well, with their hosts hoping to finally score a goal this season.

Reigning champions Bayern Munich extended their lead on Saturday with a 2-0 win at FC Cologne.

Bayern kept a clean sheet for their fourth straight Bundesliga match to move to 14 points, two points clear of Borussia Moenchengladbach.

Pep Guardiola's Munich opened on 19 minutes as Mario Goetze struck his third goal in the last two matches.

The visitors continued to press Cologne and finally doubled the lead midway through the second half as Daniel Halfar put through his own net.

Meanwhile, Gladbach won 2-1 at Paderborn thanks to early goals from Patrick Herrmann and Raffael, with Jens Wimmer getting one back for the promoted club, who had been top of the table before losing at Bayern in midweek.

Gladbach's win took them above Leverkusen, who had to play more than an hour with 10 men but held on for a 0-0 draw away at SC Freiburg.

Leverkusen defender Emir Spahic was sent off in the first half, although Freiburg also finished the game a man down after Pavel Krmas was dismissed.

The visitors might have won it but Karim Bellarabi and Son Heung-Min both hit the crossbar in the final 17 minutes.

In Gelsenkirchen, Schalke 04 picked up their second straight victory with a 2-1 win at home over bitter rivals Borussia Dortmund.

Dortmund's recent defensive struggles continued as goals from Joel Matip and Eric Maxim Choupo-Moting left them trailing 2-0 by the midway point in the first half.

Jurgen Klopp's side did reduce the deficit shortly afterwards courtesy of a Pierre-Emerick Aubameyang strike but they could not find an equaliser and have collected only seven points from six games this season, one less than Schalke.

In Wolfsburg, Ivica Olic scored in the 57th minute to secure VfL Wolfsburg a 2-1 victory at home against Werder Bremen to jump to seventh with eight points.

After Ricardo Rodriguez pushed Wolfsburg ahead in the 15th minute, Marnon Busch equalised for Bremen after 37 minutes.

Elsewhere, Hanover 96 went down 1-0 at struggling VfB Stuttgart, Daniel Schwaab scoring his team's first goal at home this season in the 69th minute, while Mainz and Hoffenheim played out a scoreless draw on Friday, the result leaving both teams with 10 points.
