Zastrow's swimming career has been filled with a series of unfortunate injuries. In 2001, despite being the 100 meter freestyle champion in Germany, a hand injury kept him from attending the FINA World ChampionshipsinFukuoka, Japan.
In 2003, at the FINA World ChampionshipsinBarcelona, Spain, Zastrow participated in his first World Championship as a Dutch citizen. However, due to a back injury, he was unable to swim in most of the events that he had qualified for.

Along with Pieter van den Hoogenband, Johan Kenkhuis, and Klaas-Erik Zwering, he was a member of the Dutch 4×100 meter freestyle relay team, which won silver by clocking in at 3:14.36.
