Hertha Berlin's Bundesliga woe continues

Hertha Berlin's losing run in the Bundesliga has stretched to four games after a 4-0 defeat at Augsburg.

"To lose like this is a slap in the mouth," Hertha's Germany defender Niklas Stark said.

Hertha goalkeeper Rune Jarstein was sent off for a desperate lunge at Sergio Cordova in the 27th minute - an unsuccessful attempt to stop the Venezuelan from scoring Augsburg's second goal.

"A goal and a red card, that's something I rarely experienced," Hertha coach Ante Covic said.

Philipp Max already grabbed the first in the 18th when his free kick evaded a host of players before nestling inside the far post.

Hertha's 20-year-old reserve goalkeeper Dennis Smarsch came on for his Bundesliga debut but was unable to prevent Augsburg substitute Andre Hahn from effectively sealing the result in the 52nd.

Florian Niederlechner completed the scoring in the 79th to lift Augsburg to 12th, two points above Hertha after its second successive win.

Defeat piles the pressure on former under-23 side coach Covic in his debut season after taking over the senior team from Pal Dardai in the summer.

"Anyone who knows me knows I'm the last to think of myself. It's only about the club that I've served for 20 years," Covic said.

Lowly Mainz moved out of the bottom three as they hammered hosts Hoffenheim 5-1 in Achim Beierlorzer's successful debut as coach in Sunday's late game.

Beierlorzer, who was fired as Cologne coach only days before taking the Mainz job, watched as his new team claimed a fourth Bundesliga win this season despite having Ridle Baku sent off through VAR at the end of the first half.

The Mainz midfielder was initially shown a yellow card for a tackle from behind on Sebastian Rudy, but it was upgraded to red after referee Bastian Dankert checked replays of the incident.

A brace from Pierre Kunde, Levin Oztunali's opener, a bizarre own goal from Pavel Kaderabek and a late Jean-Paul Boetius effort sealed the fate of Hoffenheim.

Andrej Kramaric got a late consolation goal for Hoffenheim, who failed to get a sixth-straight league win which would have lifted them to fourth.
