Midfielder Janik Haberer and ex-Bayern Munich striker Nils Petersen netted for Freiburg in Sunday's shock 2-1 win over Bundesliga high-fliers Hertha Berlin.

After pushing league leaders Bayern all the way in last weekend's 2-1 home defeat at the Schwarzwald Stadion, hosts Freiburg earned a deserved win on Sunday to climb to eighth in Germany's top flight.

Haberer, who had given Freiburg a shock lead against Bayern before Robert Lewandowski netted twice, gave the hosts the lead against Hertha when he drilled home Vincenzo Grifo's cross on 39 minutes.

Despite less than 40 percent possession, Freiburg, last season's second division champions, manage to contain Hertha's attack, led by Vedad Ibisevic, Berlin's top-scorer with eight goals this season.

Freiburg sealed the win when super sub Petersen netted his sixth goal of the season, all of which have come as a replacement, on 87 minutes when he finished off a move started by his own goalkeeper and beat three defenders.

Less than a minute later, Hertha pulled a goal back when Ibisevic's shot was saved but ex-Dortmund striker Julian Schieber rifled home.

Freiburg could have made it 3-1 when Turkish midfielder Onur Bulut forced Hertha's Norway goalkeeper Rune Jarstein to tip the ball over the bar with time running out.

The defeat, Hertha's sixth of the season, leaves Pal Dardai's Berlin sixth in the table and 15 points behind leaders Bayern, who won 2-1 at Werder Bremen on Saturday thanks to goals by Arjen Robben and David Alaba.

Also on Saturday, second-placed RB Leipzig ended 10-man Hoffenheim's unbeaten run this season with a 2-1 comeback win to stay just three points adrift of Carlo Ancelotti's star-studded Bavarians.

Hoffenheim were the last undefeated team left in Europe's top leagues before Marcel Sabitzer's 77th-minute winner dealt the visitors their first loss of the campaign after striker Sandro Wagner's dismissal.

Bayer Leverkusen, who host Atletico Madrid in the Champions League last 16 in three weeks' time, threw away a two-goal lead in their 3-2 home defeat against Borussia Moenchengladbach.

Goals by Germany defender Jonathan Tah and Javier Hernandez, 'Chicharito's first since October, put Leverkusen ahead before Gladbach fought back.

Attacking midfielder Lars Stindl scored two goals in six minutes before Brazilian striker Raffael netted the winner.

Cologne also battered bottom side Darmstadt 6-1 as Japan striker Yuya Osako scored twice.

Relegation-threatened Ingolstadt remained 16th, but boosted their survival chances with a 3-1 win over Hamburg, who drop to second from bottom.

Ingolstadt's Pascal Gross, Markus Suttner and Almog Cohen, who netted a penalty, netted before Hamburg's Japanese captain Gotoku Sakai pulled a goal back.

Wolfsburg slumped to a 2-1 home defeat against Augsburg, whose Dominik Kohr scored the winner after Halil Altintop equalised following Germany striker Mario Gomez's early goal for the Wolves.

Eintracht Frankfurt finish the weekend third thanks to Friday's 1-0 win at Schalke after Alexander Meier, the league's top scorer in 2014-15, scored a first-half winner.
