Tracy Austin, precisely 5ft 4 (162.6 cm) tall, was a diminutive dynamo who dominated professional tennis despite her petite stature.
Her compact height fueled a fierce, aggressive baseline game, propelling her to world No. 1 status and two US Open titles in 1979 and 1981, making her the youngest champion in tournament history at age 16.
Austin's 5ft 4 frame contrasted sharply with her taller sister, embodying her underdog image in a sport favoring height, yet she overcame injuries to etch a legendary career.
