Filip Krajinović

Krajinović started playing tennis in local tennis clinic TK Žak.[4] In 2006, he reached the fourth round of 2006 Orange Bowl, losing to Bernard Tomic.[5] Soon after, in 2007, he signed a contract with prestigious Nick Bollettieri Tennis Academy in Bradenton, Florida. The same year, Krajinović won four junior singles titles — Pančevo, Atlanta, Texas, and Boca Raton.[6]

In 2008, Krajinović won a junior title in Loverval.[6] He reached the third round of 2008 French Open, losing to Evgeny Donskoy.[7] At the 2008 Wimbledon Championships, he reached his first junior Grand Slam semifinal, losing to eventual champion Grigor Dimitrov in straight sets.[8][9] Krajinović also lost to Devin Britton (after winning the first set 1–6) in the semifinals of 2008 US Open.[10]

Throughout his junior career, Krajinović compiled a singles win/loss record of 54–9, reaching as high as No. 6 in the junior combined world rankings in February 2009.

Krajinović made his professional debut at the Futures event in 2008 at Miami Beach, Florida, but lost in the first round.[6] He played at several more Futures and Challengers, his best result being the semifinals in Knoxville, Tennessee, when he retired from his semifinals match against Bobby Reynolds due to a foot injury.[11] In Knoxville, he had a large group of supporters, mostly Serbian students attending the University of Tennessee. In February 2009, Krajinović played qualifications for SAP Open, but lost to Somdev Devvarman in the first round.[12] In March Krajinović was invited by Serbia Davis Cup team captain Bogdan Obradović to be with the team for their 2009 Davis Cup World Group first round tie against Spain, but didn't play in an official match.[13] In April he reached the quarterfinals of 2009 U.S. Men's Clay Court Championships qualifications in Houston, Texas, losing in straight sets to Michael Russell.[3] Krajinović received a wild card into the Serbia Open main draw, losing to Marcel Granollers in three sets in the first round.[3] In the summer, he reached the finals of three events — Futures in Chico, California and Rochester, New York, and a Challenger in San Sebastián.[3]

In February 2010, he took part in Challenger tournament GEMAX Open in Belgrade, defeating Somdev Devvarman in the first round but losing to Alex Bogdanovic.[14] Krajinović played the qualifications for the BNP Paribas Open. He defeated former French Open champion Gastón Gaudio in three sets in the first round, but then lost to Tim Smyczek in the second.[15] During the tournament, Krajinović practiced along with world No. 1 player Roger Federer.[16] Upon losing to Harel Levy in the second round of Challenger in Sunrise qualifying, he was awarded with a wild card for Sony Ericsson Open main draw,[17] where he lost to former world No. 4 player James Blake in three sets in the first round.[18] Krajinović then earned a wild card for 2010 Barcelona Open Banco Sabadell,[19] where he lost to Juan Ignacio Chela in the first round.[20] Receiving a wild card for 2010 Serbia Open, Krajinović collected his first ATP World Tour victory over Evgeny Donskoy. He then defeated Horacio Zeballos in the second round and won the first set against the first seed and world No. 2 Novak Djokovic in the quarterfinals when Djokovic retired.[21] Krajinović lost to the third seed and eventual tournament winner Sam Querrey in the semifinals. He then joined Viktor Troicki and Nenad Zimonjić in the team of Serbia at the World Team Cup in Düsseldorf, Germany.[22] Krajinović also made the second Challenger final of his career in Kosice, Slovakia.

He missed first four months of 2011 due to a shoulder injury from previous year.[23] He returned to tour for four tournaments during May and June; however, on 14 July, Krajinović took the option of having an operation to fix the persistent injury.[24]

Starting from scratch with a ranking of 1403, Krajinović returned to the ITF Futures circuit and to the ATP Challenger Tour. In May, he made his Roland Garros debut, defeating three opponents, all of whom were ranked several hundred places above him, in the qualifying round and returning to the top 500 in the process. In November, he began training at Piatti Tennis Team camp where he was coached by Riccardo Piatti and Ivan Ljubičić among others.[25][26]

He was runner-up at four Futures tournaments and finished the year ranked 226.

Krajinović won his first professional title on 6 April 2014 at the ITF tournament in Harlingen (TX, USA, 15k).[27] He followed that up with another Futures title and his first Challenger final, in which he lost to Nick Kyrgios. Later that year, he won two Challenger titles on Italian clay courts, qualified for the US Open main draw, and entered the top 100.

Krajinović earned his first direct-entry into the main draw of a major at the 2015 Australian Open; his first win at a major came at the US Open to Alejandro Gonzalez, before losing to David Ferrer in the second round. In both 2015 and 2016, Krajinović's efforts contributed to the Serbian team finishing two consecutive years in the Davis Cup quarterfinals. In 2016, he once again spent several months sidelined with injury, first in May and June, then ending his season in early September; as a result, he dropped out of the top 200.

In 2017, he won five Challenger Tour titles, all on clay: the Neckar Cup, Marburg Open, Thindown Challenger Biella, BFD Energy Challenger in Rome, and the Almaty Challenger. Krajinović broke into the top 75, after reaching the second round of Moscow as a qualifier. He made an unexpected late-season run at the Paris Masters, qualifying for only his second ATP main draw of the year. After defeating Yūichi Sugita, Sam Querrey and Nicolas Mahut, his quarterfinal opponent, world No. 1 Rafael Nadal, withdrew from their match due to injury. He then beat John Isner to reach the final, becoming the first qualifier to reach the final at Masters level since Jerzy Janowicz in 2012[28] and the lowest ranked player to compete in a Masters 1000 final since world No. 98 Mardy Fish in Indian Wells in 2008.[29] He lost to Jack Sock, but as the runner-up reached a then career-high ranking of world No. 33.

After an early exit in Qatar and missing the Australian Open due to injury, he found solid form making the final 16 in Rotterdam, losing a tight match to world No. 5 Grigor Dimitrov and a quarterfinal appearance at the Open 13. At the Dubai Tennis Championships, he made his first ATP 500 semifinal allowing him to reach the top 30. In Indian Wells, he ran into world No. 1 Roger Federer in the third round, losing in straight sets. He achieved a career-high No. 26 in ATP rankings on 23 April. He did not compete at the French Open and his season was shortened to seven tournaments in the opening seven months of season due to left foot, left ankle and hand injuries. In August, he retired in US Open first round due to cramps while trailing Matthew Ebden 4–1 in the fifth set.

At the Australian Open, he defeated world No. 18 and French Open semifinalist Marco Cecchinato in five sets to earn his first Grand Slam match victory since 2015. He assisted Serbia to qualify for the Davis Cup Finals in November. In Indian Wells, he defeated David Goffin and Daniil Medvedev before losing to Rafael Nadal in the fourth round. In Miami he defeated three-time Grand Slam champion Stan Wawrinka before losing to Roger Federer in the third round.

In February Krajinović reached the semifinals of the Rotterdam Open after besting the tournament's 7th seed Russia's Andrey Rublev in straight sets in the quarterfinals.[30]  He then lost in straight sets to the tournament's eventual champion, Gaël Monfils of France, in the semis.[31]
