Union Berlin registered their first win of the season, hammering Mainz 4-0 in their latest encounter in the ongoing Bundesliga. Before Friday, neither side had won this season prior to kick-off, but it was the home team who began more determined to change that. Union had more possession in the early stages and it was Max Kruse who opened the scoring with a powerful back-post header from Sheraldo Becker’s right-wing cross in the 13th minute. Union gained momentum but missed the chance to extend the lead at the half-hour mark after Nico Schlotterbeck pulled wide from tight angle.
