Santiago Giraldo

In October 2003, at age 15, Giraldo became the youngest player in his country to be ranked by the ATP, getting his first point with the ITF Futures tournament in Medellín. In 2005, he won his first professional tournament in Medellín, and a 15,000 dollar prize, in the ITF Futures category. In 2006, age 18, he won the Challenger de Bogotá title and reached the Challenger de Medellín final.

In March 2007, Giraldo won the Challenger de Bogotá title, beating the Brazilian Flávio Saretta, and won the Challenger de Quite against Giovanni Lapentti. He reached two finals in the same Challenger category. Although he lost to the Spanish Fernando Vicente in the Challenger de San Luis Potosí, he was close to the Top-100, reaching position 115, and also entered the Roland Garros' main draw as a "lucky loser". In October of the same year, he reached the Challenger de Bogotá final, losing to Marcos Daniel. His only ATP triumph in 2007 was beating the Venezuelan Yohny Romero in the Davis Cup, helping Colombia win the series, 3-1, against Venezuela.

During 2008, Giraldo had a 19-17 record in Challenger tournaments, he made it to the final at Challenger de Furth's final, losing to Daniel Köllerer, and to Challenger de Cali's semifinals. He made it to final draws five times, including the ATP World Tour Masters 1000 tournaments at Indian Wells and Miami. For the second consecutive year, he made Roland Garros' main draw, losing in the first round to Florent Serra.

Giraldo opened 2009 by winning the Challenger de Salinas title, defeating Michael Rusell in the final, and, in March, had his sole triumph at the ATP level in the Davis Cup match versus Uruguay. Giraldo then qualified for the Indian Wells-Masters 1000's main draw and lost in the first round to Nicolás Lapentti. One month later, Giraldo won the Challenger de San Luis Potosí's title against the Italian Paolo Lorenzi. For the third consecutive year, Giraldo entered the Roland Garros' main draw, losing to Denis Istomin in five sets in the first round. In the final stretch of the season, Giraldo won 19 out of 26 matches, reaching the Challenger de Cali and Quito semifinals and winning the Sacramento title (defeating Canadian Jesse Levine in the finals) but losing again to Nicolas Lapentti in Guayaquil's final. Giraldo qualified for the Australian Open main draw for the first time by virtue of his previous results.

Giraldo lost in the first round of 2016 Wimbledon Championships to Gilles Muller, in a match that went to 5 sets, Muller eventually prevailing, 15-13, in the last set. Giraldo won the Advantage Cars Prague Open, which included an impressive win in the quarter-finals against world number-26 Martin Klizan. Giraldo entered the new 2016 Los Cabos Open tournament. He beat Amir Weintraub in straight sets, then faced 4th seed Sam Querrey, whom he defeated in straight sets. He lost to wild-card Pablo Carreño Busta in the quarterfinals.

Giraldo has a powerful forehand stroke—with a big backswing and a forward swing that contacts the ball with extreme speed, flattening it out—that he uses to move his opponents around and end points quickly. His forehand has been likened to that of Fernando González, his coach. Giraldo also uses this technique to hit balls out wide at an acute angle, which is a signature shot of his. His forehand is known to reach speeds of up to 110 miles per hour (180 km/h). While his backhand is generally his weaker shot in terms of pace, he uses an identical technique, which makes his backhand flat and low. He is known for his flair in shot-making with both his forehand and backhand, often hitting balls with extreme pace or angles. His best shot is the running forehand.

Giraldo has a powerful return of serve. Unlike traditional good returners such as Andy Murray, Novak Djokovic, and Andre Agassi, who use anticipation and footwork to take serves early and efficiently, Giraldo stands further behind the baseline—especially on second serves—winds up a huge backswing, and takes the ball later, injecting a sudden increase in pace. He is also adept at controlling serves, such that he can hit them at acute angles with speed to finish off the point early. Giraldo's serve is not one of his strengths, but he possesses a decent flat and strong first serve and a top-spin second serve. His first serve can reach up to 120 miles per hour (190 km/h).

Giraldo's weaknesses include inconsistency and lack of agility. Because of his shot-making and hyper-aggressive style of play, he is more than prone to making unforced errors on his groundstroke rallies, more often than on his returns of serve. Because he often goes for hard, flat shots, he hits the ball into the net more often than other players. His playing style relies on dictating points and winning quickly, so he is affected by quick counter-punchers who can move him around and return his shots consistently, such as David Ferrer, Andy Murray, Novak Djokovic, and Rafael Nadal. Giraldo occasionally exhibits clumsy footwork as well, and sometimes is simply not fast enough to retrieve directed or drop shots.
