Second-half highlights:
46th minute: Mainz go close shortly after the change of ends. A corner from Caci finds the head of Lee, but his attempt sails over the crossbar.
50th minute: The visitors continue to press us hard, as Weiper redirects a cross from Kohr towards. Zetterer stretches to push it away from danger.
61st minute: A close call for the Green-Whites as Jung gets in the way of a shot from da Costa, deflecting it just enough to push the ball onto the post.
76th minute: Grüll does well to send Njinmah through on goal. The striker looks to chip the ball over Zentner, but has to watch as his attempt lands on top of the goal-netting.
81st minute: Friedl jumps to meet a corner but Zentner beats him to the ball. The rebound falls to Alvero, but he's unable to sort his footing in time to poke it over the line.
90th minute +4: Stark tosses the ball to a teammate for a throw-in and is shown his second yellow card of the night for what the referee deems to be time wasting. Friedl approaches the referee to discuss the situation and is also shown a second yellow, this time for dissent. Werder are down to just nine men for the remainder of the match.
90th minute +8: Full time. Werder hold on to get their first win of the year! Following the full-time whistle, head coach Ole Werner becomes the third Green-White to be shown a red card this evening.
Next up, Werder will travel to face league leaders FC Bayern München on Friday, 7th February (20:30 CET).
