Junior career

Quentin Halys reached four Junior Grand Slam finals, three in doubles and one in singles. Of the four finals, Halys won the 2014 French Open partnering Benjamin Bonzi. He reached a career high combined (singles and doubles) of World No. 03 on March 31, 2014. He ended his junior career with a 98–44 record on singles and 83–35 on doubles.^[3]

Quentin played in his first ITF Junior Circuit tournament in 2010 at the G4 Tournoi International de Clermont-Ferrand, as a wildcard. He lost in the first round.^[4] He reached his first final later that year, at the G5 International Junior Saint-Cyprien, in doubles. In an all-French final, Halys and Armel Rancezot lost in the super tiebreak against Julien Delaplane and Alexandre Favrot.^[5] Starting 2011, Halys entered a 17–match win streak, winning consecutively the 1st and 2nd Qatar ITF Junior Open, breaking through the qualifiers of both tournaments to win his first two singles titles. He also finished runner-up in the 1st tournament doubles.^[6][7] He streak was sniped by Belgian Clement Geens, at AEGON Junior International Nottingham, a 2-week G4 tournament. Quentin would reach the final in both singles and doubles of the 2nd week, but he won the doubles only.^[8] He would win another doubles titles in July of that year, at the Leeuwenbergh ITF G4 Junior Championships.^[9] Halys finished 2011 by playing for France at the Junior Davis Cup, where his country finished 3rd that year.^[10]

Starting 2012, Quentin played in all Junior Grand Slams but Wimbledon, where he didn't pass the third round of any of them, in singles. He reached the semifinal at Australian Open doubles. Halys only final that year was at the GA Copa Gerdau, partnering Pedro Cachín, where they lost in straight sets to the partnership of Luke Bambridge and Joshua Ward-Hibbert.^[11] He played a second year for his country at the Junior Davis Cup, this time finishing in the fourth place.^[12] In 2013, Halys reached four finals in doubles, including the US Open final, where he lost to Kamil Majchrzak and Martin Redlicki, in partnership with Frederico Ferreira Silva. All other finals were at G1 tournaments, winning only at the 35° Torneo International Citta Di Santa Croce, partnering Benjamin Bonzi.^[13] In singles, he lost in the finals of the B1 European Junior Championships to Karen Khachanov.^[14]

In his last year as a junior, Halys saw much success ahead of 2014, reaching 7 finals with four titles in doubles and one in singles. Partnering Johan Sébastien Tatlot, the pair reached the final of the Australian Open, where they lost in straight sets. The partnership would win the GA Porto Alegre Junior Championships (the successor of the Copa Gerdau) in March and the B1 European Junior Championships in July.^[15] Partnering Benjamin Bonzi, the French pair won the French Open, winning in straight sets. Quentin also won the G1 Canadian Open Junior Championships in partnership with Akira Santillan, winning only two matches to win the title, as the pair received two walkovers in the semifinals and the final.^[16] Quentin reached also the US Open in singles, losing to Omar Jasika in three sets. Earlier in July, he defeated countryman Corentin Denolly to win the B1 European Junior Championships, his last singles title in junior.^[17]
