Jaite's career-high ATP singles ranking was World No. 10, which he achieved in the summer of 1990, and he won a total of 12 titles and $1,873,881 in tour prize money during his career.
Jaite's playing style leveraged his consistency, speed, thoughtful use of tactics, and fitness to compensate for his lack of power. His best surface was clay, which allowed him to hit the ball deep to either side of the court, and gave him more time to use his defensive skills. Jaite's best shot was his topspin single-handed backhand, which was difficult for his opponent to attack.
While moving back and forth between Barcelona and Argentina as a child, Jaite was a top junior in both countries. He won the Spanish National championships, and was offered a try-out on the Argentine Davis Cup team, but declined at first because he didn't want to offend Spain. He finally joined the team, but lost to Jimmy Connors when the Argentinians faced the United States.
In 1983, Jaite joined the ATP tour and quickly moved up the world rankings; from # 826 in 1982 to # 156 in 1983 to # 54 in 1984. The following year, he won his first ATP tour title and was ranked in the world's top 20, where he remained for the next few years.
In 1985, Jaite also reached the quarterfinals of the French Open, his best Grand Slam result.
In May 1986 at Forest Hills Jaite defeated world # 4 Boris Becker, 6–2, 7–6.
In April 1989 he upset world # 8 Jakob Hlasek, 6–4, 6–1, in Monte Carlo.
Jaite became only the sixth South American to be ranked in the top 10 in the ATP computer rankings, reaching # 10 in 1990. In May 1990 he defeated world # 2 Stefan Edberg, 3–6, 6–2, 6–4, in Germany.
Jaite was involved in a Davis Cup tie against the US in Buenos Aires when Andre Agassi was leading 6–2, 6–2, 5–0. Jaite was leading 40–0 in the 6th game of the 3rd set, and missed his first serve. Agassi then called out to his then-coach Nick Bollettieri, "hey watch this, and then followed by catching the second serve in his left hand to give Jaite the game. Viewed as an act of disrepect, Agassi was booed by the crowd for five minutes.
Jaite has had an important role in Argentine tennis since his retirement. He is the tournmament director for ATP Buenos Aires, the Buenos Aires Challenger, and director of Futures events in Argentina. From July 2007 till December 2008 Jaite was coaching David Nalbandian, and helped lead him to titles in Madrid and Bercy, where he became the first man to defeat the top two players in the world, Roger Federer and Rafael Nadal, in consecutive tournaments. In 2011 Jaite was named captain of the Argentina Davis Cup team.
