Germany continued their build-up to the finals with an impressive 3-0 win over Hungary in Budapest.
Lukas Podolski opened the scoring with a fourth minute penalty before Mario Gomez scored the second midway through the second half.
Brazilian-born Cacau then came off the substitutes' bench to score the third. It was his third in two games for his adopted country after a double against Malta and presses his claims for a place in the starting line-up.
Earlier, Serbia's preparations suffered a setback in a 1-0 defeat to New Zealand, who are also heading to South Africa.
The match in Klagenfurt in Austria was decided by a goal from Shane Smeltz in the 22nd minute.
He beat Serbia goalkeeper Vladimir Stojkovic with a low shot to notch his 16th goal in 29 games for the All-Whites.
The result is setback for Serbia, who face Australia -- winners over their neighbors last week -- in Group D in South Africa, as well as Germany and Ghana.
New Zealand are in Group F with Italy, Paraguay and Slovakia.
