Guillermo Pérez Roldán
Guillermo Pérez-Roldán (born October 20 1969, in Tandil, Argentina) is a former professional tennis player from Argentina.
Pérez-Roldán was known particularly as a strong clay court player. He turned professional in 1986. Between 1987 and 1993, he won nine top-level singles titles. His best Grand Slam performance came at the 1988 French Open, where he reached the quarter-finals before being knocked-out by Andre Agassi.
He burst onto the scene as a teenager in 1988 by reaching the final of the Italian Open, where he battled Ivan Lendl in five grueling sets. Later that year, at the US Open, John McEnroe famously expressed outrage at being seeded significantly lower than Pérez-Roldán, who had not yet won a match on hard courts. However, Pérez-Roldán silenced critics by progressing further in the tournament than McEnroe.
Pérez-Roldán had an excellent junior career, winning the French Open boys championship on his favored red clay in both 1986 and 1987. He was named Rolex Rookie of the Year in 1988, influenced no doubt by his run to the finals of the Italian Open and the quarterfinals of the French Open that year. He is currently tied for tenth on the list of most titles won by a teenager in the Open Era (five).
His career-high singles ranking was World No. 13 (in 1988), and his career prize-money earnings totalled US$1,686,341. In the early 1990s his career was hamstrung by injuries and he finally retired from the professional tour in 1996.
