Mainz Crush Dortmund To Edge To Safety, Cologne stun Union Berlin

Mainz hammered a second-string Borussia Dortmund 3-0 on Saturday to haul themselves out of the Bundesliga's bottom three, as Cologne came back to beat Union Berlin in a day of much importance for the relegation battle. Sitting in the relegation playoff spot at kick-off, Mainz stunned the visitors by racing into a three-goal lead inside just 23 minutes. Leandro Barreiro opened the scoring on 12 minutes, before Lee Jae-sung grabbed two goals in three minutes as the hosts tore into a much-changed Dortmund side.

Mainz, who are now eight games unbeaten since losing 8-1 to Bayern Munich in March, realistically need just a point from their final game of the season at Wolfsburg to secure another season in the German top flight.

With Dortmund's Champions League qualification for next season now guaranteed, and a Champions League final against Real Madrid on the horizon, Dortmund coach Edin Terzic rang the changes.

Defender Nico Schlotterbeck was the only starter from the team that won in Paris on Tuesday and though Jadon Sancho, Ian Maatsen and Julian Brandt came off the bench at half-time, they could not turn the tide.

Terzic defended the decision to make sweeping changes to Dortmund's XI, insisting his choice of line-up was not unlike the team that beat Augsburg 5-1 last weekend, with three changes from that side.

"We set up the team similarly to what we did last week," Terzic told Sky Sport Germany.

"We had a similar formation, only this time we were always inferior in the duels. Mainz punished the mistakes we made in the first half with ice-cold precision. That's why it is a deserved defeat."

Dortmund now sit four points behind fourth-place RB Leipzig, who drew 1-1 with Werder Bremen earlier on Saturday.
