It was 1986 when she lost to Martina, Hanafan, that was Bettina's comeback period after 2 rather weak years in 84 and 85. For a player that was in the top 15 for about 5 years her Grand Slam record isn't good: a Wimbledon semi and a quarter, no other quarterfinal. She's got a good Federation Cup record though and played a good doubles with Eva Pfaff. The best period of her career might be from January to April 1983: Constantly being at least in the quarterfinals at any tournament, wins over Kohde, Sukova, Turnbull, Barker, and Bassett. The weakest streak was late 85: In 6 tournaments in a row she won only 1 match.
