A second-half goal from Austria striker Michael Gregoritsch took Freiburg to a narrow 1-0 win at struggling Mainz on Sunday.
Despite the scoreline the match was ripe with chances, Mainz going closest in the first half through Sepp van den Berg, while Gregoritsch was denied twice by the post.
The 1.93-metre-tall Austrian scored with 20 minutes remaining, hammering in on the turn to give his side the lead, his first league goal since May.
Mainz's Leandro Barreiro was inches away from an equaliser with just a minute remaining, but the visitors cleared the danger.
The win, Freiburg's first in the league since October, sends the Europa League participants into eighth place while Mainz remain mired in the relegation zone.
Later on Sunday, league leaders Bayer Leverkusen can go five points clear atop the Bundesliga table with a win at home over Borussia Dortmund.
Second-placed Bayern Munich however have a game in hand after Saturday's clash with Union Berlin was postponed due to heavy snowfall, with the rescheduled fixture likely to take place in 2024.
