Raised in the sea resort of Mar del Plata, Vilas was a southpaw and played his first tour event in 1969. He was in the year-ending top ten from 1974 through 1982. He was a clay-court specialist but also played well on hard, grass, and carpet surfaces.
Vilas got his first big break in the 1974 Masters tournament (played on grass), where he defeated Ilie Nastase in the final.
