Who was the first tennis player to play in five Olympic games?

Aránzazu Isabel María "Arantxa" Sánchez Vicario (born 18 December 1971) is a Spanish former World No. 1 professional tennis player. She won four Grand Slam singles titles, six Grand Slam women's doubles titles, and four Grand Slam mixed doubles titles. In 1994 she was crowned the ITF World Champion for the year.

Arantxa Sánchez Vicario started playing tennis at the age of four, when she followed her older brothers Emilio Sánchez and Javier Sánchez (both of whom became professional players) to the court and hit balls against the wall with her first racquet. As a 17-year-old, she became the youngest winner of the women's singles title at the 1989 French Open, defeating World No. 1 Steffi Graf in the final. Monica Seles broke the record the following year when she won the title at age 16.

Over the course of her career, Sánchez Vicario won 29 singles titles and 69 doubles titles before retiring in November 2002. She came out of retirement in 2004 to play doubles in a few select tournaments as well as the 2004 Summer Olympics, where she became the only tennis player to play in five Olympics in the Games history. Sanchez Vicario is the most decorated Olympian in Spanish history with four medals, two silver and two bronze.
