Metzker first showed his international pedigree in the pool at the 1976 Summer Olympics in Montreal, coming sixth in the 1500-metre freestyle and 13th in the 400-metre event.
He had his first international success at the 1978 Commonwealth Games in Edmonton, Canada, winning a gold and bronze medal in the 1500-metre and 400-metre freestyle respectively. He also claimed a gold medal in the 4×200-metre freestyle relay.
In Moscow, Metzker trailed the great Soviet swimmer Vladimir Salnikov home by some 25 seconds. Salnikov broke the world record, being the first man to break the 15-minute barrier. Metzker was pipped to the silver by just 0.19 of a second by Salnikov's compatriot Aleksandr Chaev. Metzker also reached the final of the 400-metre freestyle and the 4×200-metre freestyle relay, finishing seventh in both. Metzker retired from international competition with another gold in the 1500-metre freestyle at the 1982 Commonwealth Games in Brisbane.
