BERLIN (AP) Japan midfielder Shinji Kagawa scored Sunday as Borussia Dortmund defeated Ingolstadt and claimed its second successive 4-0 win in the Bundesliga, while Borussia Moenchengladbach slumped to its second loss.
After dominating the first half and squandering several chances, Dortmund finally made the breakthrough through Matthias Ginter in the 55th minute. The defender took Henrikh Mkhitaryan's cross and left a defender sprawling with his first touch before scoring inside the far post with his next.
Marco Reus made it 2-0 with a penalty five minutes later after Moritz Hartmann had fouled Marcel Schmelzer.
''We played well for 90 minutes, but we were annoyed at halftime that we missed so many chances,'' Schmelzer said.
Kagawa scored in the 84th after fine work from Pierre-Emerick Aubameyang on the right. Aubameyang eluded two Ingolstadt defenders, passed the ball to Jonas Hofmann, who saw Kagawa and let the Japan star do the rest, creating space before rolling the ball inside the right post.
Ginter crossed for Aubameyang to complete the scoring in injury time.
''It was an experience for my guys and I'm proud of them because they played a good game for long periods,'' said Ingolstadt coach Ralph Hasenhuettl, whose side beat Mainz on its Bundesliga debut last weekend.
Later Sunday, Mainz won 2-1 at Moenchengladbach, which was bottom of the table after two rounds.
Mainz hit the post through Yunus Malli and the crossbar through Fabian Frei before Spanish midfielder Jairo opened the scoring in the 42nd.
Patrick Herrmann equalized in the 54th, taking Lars Stindl's pass and hammering the ball inside the far post, but the home side was made to rue missed chances when Christian Clemens slotted the winner in the 79th.
''We were much better in the second half, but we missed a lot of chances and that was very costly. We conceded the winning goal out of nothing,'' `Gladbach coach Lucien Favre said. ''It didn't go for us today. We didn't use our goal chances. A 1-1 draw would have been OK.''
Moenchengladbach lost 4-0 to Dortmund in its opening game.
After two games played, Dortmund topped the table on goal difference from Bayern Munich.
''It's a very pretty picture,'' said Dortmund coach Thomas Tuchel when shown the table. ''It can stay like that.''
