Aged 14, Konjuh was the runner-up at the 2012 Wimbledon Championships in girls' doubles. In December 2012, Konjuh won two prestigious junior tennis tournaments, Eddie Herr and the Orange Bowl.[9][10][11]

In January 2013, she won the singles and doubles events at the Australian Open, and became the No. 1 junior in the world.[3] She also received a call up to the Croatia Fed Cup team,[12] where she scored the biggest win of her career, defeating Poland's Urszula Radwańska, ranked No. 37 in the world, at the age of 15.[13]

In September 2013, Konjuh won the singles title at the US Open, her second singles junior Grand Slam.[5][6][7] Despite being eligible to continue playing junior tournaments for two more years, Konjuh ceased playing junior events at the end of 2013, changing her focus to competing on the main tour in 2014.[14]

Konjuh at the 2013 US Open

Konjuh was awarded a main draw wild card for the ASB Classic in Auckland, New Zealand. On her debut at WTA-level, she stunned the top seed and world No. 14 Roberta Vinci, in the first round in three sets.[15][16] At the Australian Open, she came through qualifying to reach her first Grand Slam draw, but lost in the first round to the fourth seed and eventual champion Li Na.[17]

Konjuh underwent elbow surgery on 23 January in Zagreb.[18] Her recovery lasted four months, and she made her return in May by defeating Allie Kiick at the Open Saint-Gaudens Midi-Pyrénées.[19] Konjuh made it to the semifinals of the $50K tournament in France, before losing to the eventual champion Danka Kovinić in straight sets. This run helped her up to a new world ranking high of No. 189 and enabled her to enter the qualifying draw at Roland Garros,[20] but she again suffered defeat to Kovinić in the second round. She was more successful at Wimbledon, qualifying for the main draw with victories over Estrella Cabeza Candela, Laura Siegemund and Stephanie Vogt. She then earned her first career Grand Slam main-draw win by defeating Marina Erakovic in the first round, and followed it up with the bigger win of her career to date, toppling former world No. 12 Yanina Wickmayer in the second round. Konjuh's run came to an end in the following round with a straight-sets loss to the former world No. 1 Caroline Wozniacki.[21]

Konjuh's good form continued at the Istanbul Cup, where she came through qualifying to reach her first main-draw semifinal, defeating top-40 players Magdaléna Rybáriková and Elina Svitolina en route. Her run came to an end with a defeat to Roberta Vinci. Konjuh suffered disappointment at the US Open when she lost to Urszula Radwańska in the first round of qualifying.

In October, she competed at the Japan Women's Open in Osaka and made the quarterfinals before losing to Zarina Diyas. The result saw her ranking climb to within the top 100 for the first time, aged just 16. She completed her year by competing in three tournaments in France, reaching the semifinals of ITF events in Poitiers and Nantes, and the quarterfinals of the WTA 125K in Limoges.

In June, Konjuh competed in the main draw at the inaugural Nottingham Aegon Open and reached the quarterfinals with victories over Shelby Rogers and Casey Dellacqua. After being delayed for over two days due to poor weather, Konjuh advanced to the semifinals by defeating Sachia Vickery, and later that day reached her first WTA Tour final by beating Alison Riske. Owing to poor weather, the final was held back to Monday. Konjuh dropped the first set to Monica Niculescu, but recovered to earn victory and her first WTA Tour title. At the age of 17, she was the youngest player to win a main-tour title since Tamira Paszek in 2006.[8]

Ranked No. 87 in the world, Konjuh began the season at the Australian Open, where she lost in the second round to Daria Kasatkina, after beating Urszula Radwańska. Except for a quarterfinal appearance at the San Antonio Open, she had early exits at most of her tournaments, including Indian Wells, Miami Open and Madrid Open.

After a semifinal appearance at the Bol Ladies Open, Konjuh withdrew from the Nottingham Open owing to an injury she sustained at the previous tournament, and fell from the top 100.

After early exits at the Mallorca Open and the Aegon International, Konjuh reached the second round of Wimbledon after beating Karin Knapp. She then lost to Agnieszka Radwańska in a three-set thriller in which a late ankle injury halted Konjuh's chances of winning the match.[22] After her campaign, she returned to the top 100. Her next tournament was the Olympics in Rio de Janeiro, where she beat Annika Beck before losing to the world No. 12 Carla Suárez Navarro. Despite losing in the second round of qualifying at the Western & Southern Open, Konjuh qualified for the Connecticut Open where she reached the second round by beating Kayla Day. She then lost to Roberta Vinci in straight sets.

At the US Open, Konjuh upset the 20th seed Kiki Bertens in the first round. She went on to beat Kurumi Nara and Varvara Lepchenko en route to her first major fourth round.
