Bergström kicked off 1991 with a fair amount of success by reaching the semi-finals in Wellington and the quarter-finals in Auckland. He also reached the quarter-finals at Rotterdam, Copenhagen, Basel and Toulouse, where he upset world number 5, Michael Stich in the first round. Bergström also made two semi-finals, in Munich where he beat Thomas Muster and in Båstad. His best result in a Grand Slam, was once again at Wimbledon, where he beat Brad Gilbert on his route to the round of 16.
