Boetius set up Mateta's first on a counterattack six minutes later, and was again involved when he played Spanish defender Aaron in to set up Mateta's second in the 33rd. Freiburg had had almost 75% possession, was winning more challenges and had had more efforts on goal.
Coach Christian Streich made two changes at the break, but Freiburg found Mainz goalkeeper Florian Mueller in excellent form — and was again dealt a lesson in efficiency. Karim Onisiwo made it 4-0 in the 73rd — again set up by Boetius — four minutes before Mateta rubbed salt in Freiburg's wounds by completing his hat trick.
