A professional tennis player for 13 years, Miriam Oremans never won a WTA singles tournament, despite playing five finals. She twice reached the final at Rosmalen (1997, 1998), near her home town Berlicum, but lost both matches. She was more successful in doubles play, winning titles in Linz (1992), Rosmalen (1998) and Paris (1999), partnering Belgium’s Sabine Appelmans in the latter two tournaments. In mixed doubles, she reached the 1992 Wimbledon final with Jacco Eltingh but lost to Neiland/Suk. In 1997, she lead the Dutch team to the Fed Cup final, which they lost 1-4 in front of a home crowd. Playing with Kristie Boogert at the Sydney Olympics, Oremans reached the doubles final, facing Venus and Serena Williams. The Dutch duo had no illusions about the final, and were happy with their silver medal following a 6-1, 6-1 defeat at the hands of the Williams sisters.
