Since we just had the thread regarding Becker and Edberg bumped up, I thought this would be a nice female counterpart to it. Both Women have 5 slams and for a short time were arguably the most dominant player in their times (Hingis in 1997, Gibson in 1957-58 ). Both also were well accomplished doubles players, each having a career slam in doubles. Hingis won 3 straight Australian Opens and made 6 straight finals, made 5 consecutive slam finals starting with the 1997 Australian, winning 4 of them. Gibson won the last 4 grand slam tournaments she played, winning Wimby and the US Open in 1957 and defending both in 1958. Both were 1 win away from a career slam in singles. Hingis has a multitude of non slam singles titles to her credit and one of the highest total weeks @ number 1 ever, Gibson made the finals of 7 of the last 8 slams she played, winning 5 of those finals. Who does everyone think rates higher on the all time list?
