Marin Čilić Bio
Marin Čilić is a Croatian professional tennis player born on 28 September 1988 in Medjugorje, SR Bosnia and Herzegovina. Standing 1.98 m (6 ft 6 in) tall and playing right-handed with a two-handed backhand, Čilić turned professional in 2005 and has spent more than two decades on the ATP Tour. He is best known for a thunderous serve, heavy baseline groundstrokes, and one of the most successful careers ever produced by Croatian tennis.
Across his career, Čilić has won 21 ATP Tour-level singles titles, reached a career-high ranking of world No. 3 on 29 January 2018, and lifted a Grand Slam trophy at the 2014 US Open. He also finished as runner-up at the 2017 Wimbledon Championships and the 2018 Australian Open, won the 2018 Davis Cup with Croatia, and earned an Olympic silver medal in men’s doubles at the Tokyo 2020 Games. He is widely considered one of the greatest Croatian tennis players in history alongside Goran Ivanišević and Iva Majoli.
Early Life and Background
Marin Čilić was born in Medjugorje, a town in the Herzegovina region of Bosnia and Herzegovina, to Bosnian Croat parents and was raised as a Catholic. He has three older brothers, Vinko, Goran, and a younger brother Mile, who also plays tennis. His father, Zdenko Čilić, was determined that his sons would have sporting opportunities he did not have growing up.
When the first tennis courts in Medjugorje were built in 1991, Marin and his friends were among the first to play on them, sparking an early passion for the sport. At the recommendation of Croatian star Goran Ivanišević, in 2004 at the age of 15, Čilić moved to San Remo, Italy, to train with Ivanišević’s former coach, Bob Brett. This step set the foundation for his transition from a promising junior to a future ATP contender.
Path to Professional Tennis
Čilić began playing on the junior ITF circuit in spring 2004, focusing initially on clay courts. He won the La Vie Junior Cup Villach in singles and the Dutch Junior Open in doubles, then qualified for the 2004 US Open boys’ event, where he lost in the second round to Sam Querrey. Before representing Croatia, he had earlier played for Bosnia and Herzegovina as a junior.
In 2005, he won the French Open Boys’ singles title, beating Andy Murray in the semifinal and Antal van der Duim in the final, and finished the year ranked No. 2 behind American Donald Young. While on the junior circuit, he captured six singles titles and four doubles titles with his Canadian partner, Greg Kates. This junior success convinced him and his team that a full-time professional career was the right next step.
Marin Čilić Career
Early Career (2005–2007)
Čilić began his professional journey in 2004 with a Futures event in Croatia, finishing the year tied at No. 1463 on the ATP rankings. In 2005, he played seven Futures events, winning the Croatia F3 title, competed in two Challenger tournaments in Zagreb and Geneva, and made his ATP-level debut at the Croatia Open, finishing the season ranked No. 587. The following year, he balanced Futures, Challenger, and International Series events, reaching the semifinals at Gstaad and ending 2006 ranked No. 170.
In 2007, Čilić won his first two professional titles at the Casablanca Challenger and the Rijeka Challenger. At the Queen’s Club Championships, he upset Tim Henman in the first round and reached the quarterfinals, where he fell to Andy Roddick, breaking into the top 100 for the first time. He also represented Croatia in Davis Cup play, beating Benjamin Becker of Germany in a World Group playoff rubber.
ATP Breakthrough (2008–2010)
Čilić’s breakthrough came in 2008, when he reached the fourth round of the Australian Open, beating 2007 finalist Fernando González along the way, and matched that run at Wimbledon. At the Pilot Pen Tennis tournament in New Haven, Connecticut, he won his first ATP singles title, defeating Mardy Fish in the final, and entered the US Open as a seed for the first time at a Grand Slam.
In 2009, he added titles in Chennai and Zagreb, upset second seed Andy Murray in straight sets at the US Open, and reached his first major quarterfinal in New York. The 2010 season marked his arrival as a top-tier player: he won the Chennai Open, defended his Zagreb title, and became the first Croatian to reach the Australian Open semifinals, where he lost to Andy Murray. By the end of 2010, he had broken into the world’s top 10 at No. 9.
2014 US Open Champion Era (2011–2015)
From 2011 to 2013, Čilić added ATP titles in Saint Petersburg, Queen’s Club, and Zagreb, while continuing to perform well at the Slams. In 2013, he tested positive for the banned substance nikethamide, originally receiving a nine-month ban that was later reduced to four months by the Court of Arbitration for Sport. He responded by hiring Goran Ivanišević as his new coach at the end of 2013.
The partnership bore fruit in spectacular fashion in 2014. After winning titles in Zagreb, Delray Beach, and Moscow, Čilić reached the US Open final and defeated 10th seed Kei Nishikori in straight sets to claim his first major title, becoming the first Croatian man to win a Grand Slam since his coach Ivanišević in 2001. He followed up by helping Croatia defeat the Netherlands in a Davis Cup World Group playoff and qualified for the ATP World Tour Finals.
Wimbledon Finalist and World No. 3 Era (2016–2018)
In 2016, Čilić won his maiden Masters title at Cincinnati, defeating Andy Murray in straight sets to end Murray’s 22-match winning streak, and captured his first ATP 500 title at the Swiss Indoors. He also reached the Davis Cup final with Croatia, falling just short against Argentina. A year later, at the 2017 Wimbledon Championships, he battled through five-set wins over Gilles Müller and Sam Querrey before losing the final to Roger Federer.
His 2018 season was historic. Čilić defeated world No. 1 Rafael Nadal en route to the Australian Open final against Federer, becoming the first Croatian to reach the Melbourne final and rising to a career-high No. 3 ranking. He won a second Queen’s Club title, saving a match point against Novak Djokovic, and then led Croatia to its first Davis Cup title by beating Lucas Pouille in the decisive rubber against France in Lille.
Veteran Comeback Era (2019–Present)
From 2019 onward, Čilić dealt with injuries and ranking drops, but continued producing signature results. In 2021, he won titles in Stuttgart and St. Petersburg to reach 20 career singles titles, earned Olympic silver in men’s doubles at the Tokyo 2020 Games with Ivan Dodig, and returned to the top 30. In 2022, he reached his first French Open semifinal and returned to the top 15.
After knee surgery in 2024, he returned ranked No. 777 and won the Hangzhou Open, becoming the lowest-ranked ATP title winner since the modern ranking system began. In 2025, he lifted Challenger titles in Girona and Nottingham, upset world No. 4 Jack Draper at Wimbledon for his first top-five win since 2022, and reached the round of 16 at the Swiss Indoors. In 2026, he recorded his 600th career ATP win at the Dallas Open, becoming the first man born in 1988 or later to reach that milestone.
Driving Style and Strengths
Čilić built his game around a powerful first serve, flat penetrating groundstrokes, and patience from the baseline. His height allowed him to generate heavy topspin and high net clearance, making him especially dangerous on fast indoor hard courts and grass, where his serve could dominate sets. Over the years, he improved his transition game, net play, and return depth, and his long partnership with coaches Bob Brett, Goran Ivanišević, and others helped refine his tactical awareness in pressure moments.
Notable Events and Milestones
Signature moments include his 2014 US Open title run, his Wimbledon final appearance in 2017, his Australian Open final in 2018, and his decisive Davis Cup victory over Lucas Pouille in 2018. He also reached 600 career ATP wins in 2026, the lowest-ranked ATP title in 2024, and an Olympic silver medal in Tokyo 2020. His 5-hour, 31-minute win over Sam Querrey at 2012 Wimbledon remains one of the longest matches in the tournament’s history.

Marin Čilić Family
Family Background and Tennis Lineage
Marin Čilić comes from a Bosnian Croat family in Medjugorje, where his father, Zdenko Čilić, was determined that his sons would have sporting opportunities he did not. Marin grew up alongside three brothers, Vinko, Goran, and a younger brother Mile, who also plays tennis. The introduction of tennis courts in Medjugorje in 1991 gave the young Čilić a place to start, and a recommendation from Goran Ivanišević launched his professional journey.
Personal Life
On 28 April 2018, Čilić married his long-time girlfriend, Kristina Milković, in Cavtat, Croatia. The couple has two sons, Baldo and Vito. The family has been based in Monte Carlo, Monaco, for several years, in line with the residence registered on the ATP Tour.
2025 Season Performance
Marin Čilić’s 2025 season has been defined by a steady climb back toward the top of the game. He captured his first Challenger title in 17 years at the 2025 Girona Challenger, breaking Andy Murray’s record for the longest gap between Challenger titles. Later in the season, he won the Lexus Nottingham Open to return to the top 100 in the ATP rankings and became the oldest grass-court champion in Challenger history.
At the Grand Slams, he made a memorable return to the French Open after a long absence, having entered the main draw as a lucky loser, and at Wimbledon he earned a direct main-draw entry and produced one of the shocks of the tournament by upsetting world No. 4 Jack Draper in the second round. It marked his first top-five win since 2022. He later reached the round of 16 at the Swiss Indoors in Basel, losing to Félix Auger-Aliassime.
Heading into 2026, Čilić recorded his 600th career ATP win at the Dallas Open, becoming the first man born in 1988 or later and only the second active player after Novak Djokovic to reach that milestone. He also tied Goran Ivanišević at the 2026 Australian Open with his 599th win before losing in the third round to Casper Ruud. With form trending up and fitness improving, Čilić enters 2026 as a dangerous floater in any draw and a respected leader in the Croatian tennis setup.
