Although Thomas Tuchel's 100th game as Mainz coach lacked the drama of most of the previous 99, he said he could "live with" a 0-0 draw against Wolfsburg which practically secured their place in the Bundesliga next season.
With a nine-point advantage over 16th-placed Cologne and a goal difference superior by 29, Mainz can now plan for a fourth season in the top flight after Friday night's stalemate.
"It was not a typical goalless draw, but I can live with it," he said. "I am delighted that we are now safe.
"We played a good game for long periods and tried to create chances out of our possession.
"Wolfsburg defended very attentively and we also had to be alert as we searched for a goal.
"We knew that beforehand and I am pleased with my side's attentiveness and their performance."
The goalless draw all but ends Wolfsburg's hopes of playing in Europe next season as they could fall six points behind the top seven by the end of the weekend.
But their coach Felix Magath still saw the positive side, saying his side have "come a step further forwards, particularly compared to last season".
He added: "I think it was a fair draw."
