Top-ranked Germany routed Canada 6-0 for its biggest win in the field hockey World Cup in 32 years on Wednesday.
Only a 7-0 win over India in 1976 was bigger for the world and Olympic champions.
Germany has four points from two matches in Pool A, while Canada remain winless after its worst World Cup defeat.
Germany went ahead after only three minutes when Benjamin Wess pushed the ball past the Canada goalkeeper Dave Carter after receiving a timely pass from Deecke.
Then three successive goals off penalty corners in a six-minute span took the steam out of Canada as Jan-Marco Montag, captain Maximillian Muller and Martin Haner all found the target to give Germany a 4-0 advantage by half-time.
Man of the match Florian Fuchs’ completed the scoring with two brilliant field goals in the second half.
