In the first round of the 2003 Wimbledon Championships, Sluiter stunned 20th seed and former World #1 Yevgeny Kafelnikov in five sets for one of the biggest wins of his career.
Sluiter turned professional in 1996, and broke into the ATP top 100 for the first time in 2000. In the same year, Sluiter qualified for his first Grand Slam tournament at the 2000 Australian Open, where he defeated Andrea Gaudenzi in five sets in the first round for his first Grand Slam victory.

Sluiter was part of the Netherlands team which reached the semi-finals of the 2001 Davis Cup. In his only rubber of the tie, Sluiter faced a rematch against Arnaud Clément, who had defeated him at that year's Wimbledon, but was forced to retire while leading 2–1 in the third set. The Dutch team went on to lose the tie 3–2.

In the following round, he lost to Alexander Popp in another five-set match. That year also saw Sluiter reach his career high singles ranking of world No. 46. On 20 November 2006, Sluiter dropped out of the top 100 for the last time, but continued to be ranked in the top 200 until his retirement in 2008. Sluiter's final tournament was to be the 2008 ABN AMRO World Tennis Tournament in his hometown of Rotterdam. Having received a wild card into the main draw of the tournament, Sluiter was defeated by eventual champion Michaël Llodra in the first round. In 2009, Sluiter made a comeback to professional tennis. In June, he received a wild card to the 2009 Ordina Open in Rosmalen. Despite being ranked 866th in the world at the time, Sluiter reached the final of the tournament, where he was defeated by Benjamin Becker. This made him the lowest ranked player ever to reach an ATP tour final. Sluiter announced his second retirement in 2010.
