BERLIN (AP) — Two former Union Berlin players scored to help Borussia Dortmund come from behind and beat their old team 4-2 in the Bundesliga on Saturday, stretching the visitors’ losing streak to seven games across all competitions.

Niko Schlotterbeck and Julian Ryerson netted in the second half for Dortmund, which recovered from 2-1 down at the break with Leonardo Bonucci scoring his first Bundesliga goal for Union.

Serhou Guirassy's hat trick helped Stuttgart come from behind to beat Wolfsburg 3-1. The Guinea player took his league tally to 13 goals in seven matches.

Stuttgart’s win lifted the club to the top of the league before Bayer Leverkusen and Bayern Munich play on Sunday, when Leverkusen hosts Cologne for the Rhine derby and Bayern hosts Freiburg.

Also, promoted Darmstadt won 2-1 at Augsburg, and Leipzig drew with Bochum 0-0.

Werder Bremen was hosting Hoffenheim later.
