Early career Sock began playing in
Futures tournaments in 2009, winning his first senior tournament on that circuit in November 2009. He entered his first qualifying draw for an
ATP tournament at the
2010 Miami Masters. His first main-draw match as a professional came at the
2010 US Open, where he lost to
Marco Chiudinelli. In 2011, he reached the final of the USA F3 tournament. He also began to play in a few tournaments at
Challenger level, with his biggest success being a quarterfinal at the
Dallas Challenger. He competed in the main draw of the
2011 Miami Masters. As 2010 US Junior champion, he received a wildcard into the
2011 US Open, winning his first ATP match against
Marc Gicquel in four sets. He advanced to play
Andy Roddick, a fellow
Nebraskan, in the second round; however, he lost in straight sets. Sock's real breakthrough came in the
mixed doubles, however, where he advanced to the final alongside
Melanie Oudin, defeating the defending champions
Bob Bryan and
Liezel Huber in the second round. In the final, Sock and Oudin defeated
Gisela Dulko and
Eduardo Schwank in three sets to win their first Grand Slam title, both individually and together. After winning his first Grand Slam title, Sock returned to competing on the Challenger Tour. His most successful tournament was the
Sacramento Challenger, in which he reached the quarterfinals of the
singles tournament and, partnering with
Nicholas Monroe, the final of the
doubles tournament. Sock finished 2011 ranked No. 381 in singles and No. 370 in the doubles. In 2012, Sock won the Futures tournament at
Plantation, as well as losing in the doubles final. Stepping back up to the Challenger level, he competed at the
Honolulu Challenger, making the quarterfinals of the singles tournament and, alongside
Nick Monroe, once again made the final of the doubles tournament. Sock played in the
2012 Campbell's Hall of Fame Tennis Championships, and lost in the second round to
Izak van der Merwe. Sock's next tournament was the
2012 BB&T Atlanta Open. He upset the seventh seed,
Alex Bogomolov, Jr. He made it to the quarterfinals, where he lost to
John Isner. At the
US Open, Sock defeated the 22nd seed,
Florian Mayer, in the first round when Mayer retired. He then went on to defeat world No. 85
Flavio Cipolla of Italy in straight sets, setting up his first ever Grand Slam third round match against 11th seed
Nicolás Almagro, but was defeated in four sets. In the final two months of the 2012 season, Sock reached his first two Challenger Tour finals, winning at
Tiburon in October and finishing as runner-up in the November
Champaign-Urbana Challenger. These finals helped him rise to the top 150 for the first time.
2013: Top 100 Sock had a slow start to 2013, losing in qualifying at the
Brisbane International and the
2013 Australian Open. However, he received a wildcard entry into the
U.S. National Indoor Tennis Championships, in which he gained his first wins of the season, reaching the quarterfinals for the second time in his career. In the doubles competition at the same tournament, Sock teamed up with
James Blake, also a wildcard entry, reaching the final, where the pair lost to the
Bryan brothers. Sock made it through three rounds of qualifying without dropping a set to enter the main draw of the
2013 French Open. In the first round, he defeated the accomplished player
Guillermo García López in only 1 hour and 59 minutes. He then lost to 35-year-old veteran
Tommy Haas in straight sets. He tried to qualify for
Wimbledon for the first time, but although seeded second, lost to
Mischa Zverev. He returned to the US to win his second career Challenger level title in Winnetka, Illinois on July 6, allowing him to break into the top 100 for the first time in his career. At the
US Open, he defeated
Philipp Petzschner in the first round, going 5 games to 2 up in the third set before Petzschner retired. Sock then went on to beat
Maximo Gonzalez, However, he lost to 18th seed
Janko Tipsarević in the third round. Following the US Open, his ranking rose to No. 86.
2014: Major doubles title (pictured in 2015) won the gentlemen's doubles title at the
2014 Wimbledon Championships Sock began his 2014 campaign in
Auckland against Frenchman
Adrian Mannarino. His aggressive playing style was too much for his opponent, and he won in straight sets to set up a match with German second seed
Tommy Haas. In a considerable upset, Sock defeated the world No. 12 in straight sets to advance to the quarterfinals. There he faced Spaniard
Roberto Bautista Agut, but lost in straight sets. He then gained his first direct entry into the
Australian Open main draw, after having failed to qualify the previous year. He started strongly, defeating German
Tobias Kamke in four sets in his opening match, before losing to former world No. 7
Gaël Monfils in the second round. At
Wimbledon, Sock at the last moment teamed up with Canadian
Vasek Pospisil, and they won the men's doubles title in a five-set final against the top seeds,
Bob and Mike Bryan. Sock beat
Bernard Tomic and world No. 6
Kei Nishikori to reach the third round of the
2014 Shanghai Rolex Masters. In December, he underwent hip surgery, sidelining him for the start of the 2015 season.
2015: Top 25, First ATP singles title After missing the first two months of 2015 ATP season, Sock made his return at
2015 BNP Paribas Open. He won his first three matches, including victories over seeded players
Gilles Müller and
Roberto Bautista Agut. He lost in the fourth round to second seed
Roger Federer in straight sets. In doubles, he resumed his partnership with Pospisil to win their first Masters level tournament. His second tournament was the
2015 Miami Open, in which he won his first two matches, including beating 21st seed
Fabio Fognini, before losing to
Dominic Thiem in the third round. He made the doubles final, again partnering with Pospisil, but lost in a third-set tiebreaker to the Bryan brothers. Sock continued his successful start to the year by winning his first ATP tournament, the
2015 U.S. Men's Clay Court Championships. En route to the title, he knocked off second seed
Roberto Bautista Agut, fifth seed
Santiago Giraldo, third seed
Kevin Anderson, and eighth seed
Sam Querrey in the final. He then competed in the
2015 Mutua Madrid Open in Spain, advancing to the second round by beating wildcard
Pablo Andújar in straight sets, before losing to 12th seed
Jo-Wilfried Tsonga. At the French Open, Sock upset 10th seeded
Grigor Dimitrov in the first round in straight sets. He continued his run by beating
Pablo Carreño Busta in four sets and teenager
Borna Ćorić in straight sets. At age 22, he became the youngest American to reach the round of 16 at the French Open since Pete Sampras in 1993. In the fourth round, he lost in four sets to defending champion
Rafael Nadal. Sock collapsed at the
US Open, and was forced to retire against
Ruben Bemelmans despite being ahead in the match. On November 2, Sock reached the top 25 for the first time in his career. For the second straight year, he and Pospisil finished 9th in the ATP Doubles Race to London rankings, just barely failing to qualify for the year-end championship tournament.
2016: Olympic medals, American singles No. 1 Sock began his season at the
2016 Hopman Cup, representing the USA alongside
Serena Williams, who was ultimately replaced by
Victoria Duval due to injury. In the round-robin stage, Sock's only singles win was over
Jiří Veselý. Sock and Duval recorded wins in the mixed doubles over Ukraine and the Czech Republic. They did not proceed to the final. At the
Auckland Open, Sock reached his third career ATP final by beating a top-10 player
David Ferrer for the second time in his career, despite losing the first set and battling flu-like symptoms. He ended up retiring in the final due to that illness. Sock began the clay-court season by reaching his second consecutive final in
Houston, but was unable to defend his title after struggling with an injury in the last set of the final. Sock played in all three tennis competitions at the Olympic Games in
Rio de Janeiro. Despite losing in the first round in
singles, he earned a bronze medal in
doubles with
Steve Johnson and a gold medal in
mixed doubles with
Bethanie Mattek-Sands. At the
Shanghai Masters, Sock defeated
Milos Raonic for the first time in their last nine matches to reach his first career Masters quarterfinal. With this run, he became the top-ranked American for the first time in his career.
2017: World No. 8, Masters title, ATP Finals Once again, Sock opened up the season with the
Hopman Cup and the
Auckland Open. He reached the final at the Hopman Cup with
Coco Vandeweghe while dropping just one set in the three round-robin matches, but lost in the final to the French team of
Richard Gasquet and
Kristina Mladenovic. Sock then followed this performance with an even better result at the Auckland Open by reaching the final for the second year in a row, this time winning the title against
João Sousa. With the win, he moved into the top 20 for the first time. Sock finished his stretch down under by making his first appearance in the third round of the Australian Open, where he lost to
Jo-Wilfried Tsonga. In February, Sock returned home to the United States where he helped the
Davis Cup team sweep their 1st-round rubber against
Switzerland. At the end of the month, he played at the
Delray Beach Open and won his second title in two months after
Milos Raonic withdrew from the final with a hamstring injury. This title took Sock to a career high of 18 in the
ATP rankings. Sock continued his impressive streak of deep runs in Masters events by reaching his first career Masters semi-final at the
BNP Paribas Open in Indian Wells. Along the way, he upset No. 13
Grigor Dimitrov and No. 5
Kei Nishikori, the latter of which was his first career victory over a Top 5 opponent. After a relatively quiet middle of the season, Sock finished the year strong by winning the biggest tournament of his career at the
Paris Masters, defeating
Filip Krajinović in the final. He became the first American to win a Masters event since
Andy Roddick won the
Miami Masters in 2010, and the first to win the Paris Masters since
Andre Agassi in 1999. This result was particularly impressive because Sock was a game away from going out in his first match, when he was down 5–1 to
Kyle Edmund in the third set. With the win, Sock also made his debut in the Top 10, finished the year as the top-ranked American, and qualified for the
2017 ATP Finals. He was the first American to qualify for the year-end championships in singles since
Mardy Fish in 2011. In the final tournament of the year, Sock rebounded from an opening match loss to
Roger Federer to finish second in the
Boris Becker group. In the round robin, he won matches against World No. 5
Marin Čilić and then World No. 3
Alexander Zverev, the latter of which was the first Top 3 opponent he ever defeated. Although Sock would lose to eventual champion
Grigor Dimitrov in the semifinals, the two wins solidified his year-end ranking in the top 10 at No. 8 in the world.
2018: Wimbledon, US Open & Tour Finals doubles titles Sock was unable to match his success at the
Hopman Cup and the
Auckland Open from the previous year. Struggling with fitness issues, he won just one match between those two tournaments and the
Australian Open, where he lost in the first round to
Yūichi Sugita for the third time in the last six months. In particular, the tournament organizers in Auckland criticized Sock for showing a lack of effort in his match against
Peter Gojowczyk and considered withholding the $100,000 appearance fee they promised him for playing in the event. Sock's poor start to the season continued at the
2018 Delray Beach Open, where as the top seed and defending champion he lost in the second round to
Reilly Opelka ranked number 228. However, he did win the doubles title, partnering with
Jackson Withrow. Sock's singles struggles continued into Indian Wells and Miami. In singles at the
2018 BNP Paribas Open, Sock recorded a 6–2, 7–5 win over
Thomas Fabbiano in the round of 64, but then fell 6–7, 6–4, 4–6 to
Feliciano López. However, Sock won the doubles title with his partner, John Isner, after recording impressive victories over
Ivan Dodig and
Rajeev Ram,
Oliver Marach and
Mate Pavić, and Bob and Mike Bryan. In singles at the
2018 Miami Open, Sock recorded a 6–3, 7–6 win over
Yuki Bhambri the round of 64, but then fell 7–5, 6–7, 3–6 to rising star, Borna Ćorić. Sock and his partner, Nicholas Monroe, failed to record a win in doubles with a 1–6, 6–7 loss to
Jean-Julien Rojer and
Horia Tecău in the round 32. Sock's struggles in singles continued at the
French Open and
Wimbledon where he recorded first round losses at both events including a loss from two sets up against the Italian
Matteo Berrettini at the latter event. Both losses were marked by profane outbursts and constant complaining from Sock. For this, Sock was fined $5,000. At Wimbledon, a spectator even shouted at Sock, "Put a sock in it, Jack!" Sock's success in doubles continued as he won Wimbledon along with his doubles partner,
Mike Bryan. During the American Summer, Jack Sock once again lost in the first round at both the
Roger's Cup and
2018 Western & Southern Open. This was followed by a second-round exit to Nikoloz Basilashvili at the
US Open singles. Continuing his partnership with Mike Bryan, he achieved his first
US Open Men's doubles trophy, defeating
Łukasz Kubot and
Marcelo Melo in straight sets. As with last year, Sock was invited to the
2018 Laver Cup as part of Team World. He was defeated by Kyle Edmund by 6–4, 5–7, 10–6 in the afternoon session of the first day. His partnership with Kevin Anderson was more successful, winning 6–7(5), 6–3, 10–6 against
Roger Federer and
Novak Djokovic. The second evening doubles session saw him partner up with
Nick Kyrgios, scoring a straight-sets victory over Grigor Dimitrov and David Goffin. The final doubles match of the Laver Cup saw him and countryman
John Isner triumph over Roger Federer and
Alexander Zverev over two sets and a tight super-tiebreak. Sock's efforts propelled Team World to a first-ever lead over Team Europe by 8–7, though Team Europe claimed the Cup at (13-8) after winning its next two singles matches. The fall Asian swing started poorly for Sock. He was defeated in his first match of the China Open by
Nikoloz Basilashvili. Competing in doubles with countryman
Nicholas Monroe, he lost in straight sets to
Denys Molchanov and
Igor Zelenay in the first round. At the
Shanghai Masters, Sock was seeded 12th in singles but lost to
Peter Gojowczyk in the first round. Sock and
Mike Bryan were the top seeds in doubles, but lost in the first round to
Horacio Zeballos and
Julio Peralta. Sock's best singles results in 2018 came at his title defense at the
Paris Masters. Seeded sixteenth, he defeated
Richard Gasquet and
Malek Jaziri in straight sets to reach the quarterfinals. There, he was defeated by sixth seed
Dominic Thiem. This loss saw him fall 82 ranking places in a single week, to No. 105. Being the only team to win two Grand Slams during the year, Sock and
Mike Bryan qualified on 14 October 2018 as the 5th seeds in doubles for the
2018 ATP Finals, where they defeated
Pierre-Hugues Herbert and
Nicolas Mahut to win the title.
2019: Injuries and return to competition Sock did not participate in any tournaments during the lead up to the
Australian Open, an event in which he entered as a wild card and lost in the first round to Australian wild card
Alex Bolt, 6–4, 3–6, 2–6, 2–6. Following the tournament, he suffered an injury during a practice to two ligaments in his thumb, which required operation and left him struggling to complete tasks such as opening bottles or brushing his teeth.
