Nicknamed "Susi" in his early days because of his long hair, he spent his entire career with Borussia Dortmund, appearing in nearly 600 official games in 17 seasons. Subsequently, he went on to serve as the club's sport manager.
Zorc played 463 Bundesliga games for Borussia Dortmund (a club record) between 1981 and 1998, also being for many years the team's captain, and was hugely popular with the supporters. He also ranked, at one time, the club's second all-time top goalscorer, thanks in part to his excellent penalty-taking ability. He made his professional debut on 24 October 1981 in a 0–2 away loss against SV Werder Bremen, becoming an automatic first-choice from his second season onwards.
The tail-end of Zorc's career saw also his greatest successes, as Dortmund were twice crowned national champions, as well as winning the 1996–97 UEFA Champions League and the Intercontinental Cup. He scored in double digits in seven seasons, including 15 apiece from 1994–96.
Zorc played seven times for the German national team, but never made the squad for any international tournament. His debut came on 16 December 1992, at already 30, during a 1–3 friendly defeat with Brazil.
