Pierre-Emerick Aubameyang scored a hat-trick on his Bundesliga debut to give Borussia Dortmund a 4-0 win at Augsburg in the opening round of the German league on Saturday.

Gabon international Aubameyang — a 13 million-euro ($17 million) offseason signing from French side Saint-Etienne — opened the scoring in the 24th minute, made the game safe in the 66th, and added another in the 79th before Robert Lewandowski scored from a penalty kick with four minutes remaining.

Hertha Berlin celebrated its return to the Bundesliga with a 6-1 rout of visiting Eintracht Frankfurt, thanks to two goals each from Adrian Ramos and Sami Allagui and one each from Ronny and German-American defender John Anthony Brooks.

Bayer Leverkusen won 3-1 at home over Freiburg, Hannover beat nine-man Wolfsburg 2-0 at home, and Nuremberg drew 2-2 at Hoffenheim.

Later Saturday, promoted Eintracht Braunschweig hosted Werder Bremen, its first game in Germany's top division in 28 years.

The 24-year-old Aubameyang became only the sixth player in the Bundesliga to score a hat trick on his debut. He beat a defender to meet Marcel Schmelzer's cross with a header beyond the helpless Augsburg 'keeper.

Marco Reus set up his second, which Aubameyang curled around the goalkeeper inside the far post.

Aubameyang rounded the goalkeeper for his third, tucking the ball into the empty net, after Lewandowski had played the ball into his path.

Lewandowski added a fourth with an emphatic penalty, after Jonas Hofmann was fouled in the area.

Despite the scoreline, Dortmund found it hard to break down the stubborn home side.

Augsburg might have equalized in the first half but for a goal-line clearance from Sven Bender, while reserve goalkeeper Mitch Langerak pulled off a great save from Raphael Holzhauser.

Langerak maintained his record of 11 wins from 11 competitive games for Dortmund.

Ramos scored Hertha's first goal back in the Bundesliga following a well-worked counterattack in the 18th, and Brooks made it 2-0 by shooting through a host of players in the 32nd.

Alexander Meier pulled one back from the penalty spot five minutes later, but Allagui scored twice in as many minutes to decide the game with half an hour remaining, before Ramos and then Ronny completed the rout.

It was the first time since December 2004 that Hertha scored six goals in a Bundesliga game. The home side also hit the crossbar three times in the first half.

Freiburg striker Mike Hanke cancelled out Stefan Kiessling's opening goal for Leverkusen, but Son Heung-min scored his first Bundesliga goal for Leverkusen just after the break and Sidney Sam secured the win in the 52nd.

Leon Andreasen and Szabolcs Huszti scored for Hannover, either side of the sendings off of Maximilian Arnold and Timm Klose for Wolfsburg.

Mike Frantz and Daniel Ginczek drew Nuremberg level at Hoffenheim, which had gone ahead through David Abraham and Anthony Modeste.

The home side was left to rue a goal that wasn't given in first half injury time, when the ball came back out over the line due to the spin from Kevin Volland's header.
