The Swede was also a finalist in two other events, but was unable to add any more titles. As a singles player he had his best result in the 1988 Athens Open, where he reached the semi-finals. He took part in the main draw of two Grand Slams during his career, both in 1993 and in doubles.
At the French Open that year, Allgardh played beside Sander Groen and they lost in the opening round.

Singles: (1)
Doubles: (7).
