Back in 2017, Borna Coric won the first ATP title in Marrakech but made no progress on the ATP ranking list at the end of the year, lingering just inside the top-50 where he was in January as well. In a previous couple of years, Borna had worked with various coaches, including Miles Maclagan, Ivica Ancic, Zeljko Krajan and Thomas Johannson, failing to take his game to a higher level and deciding to change the approach ahead of 2018 season.
Setting no goals in terms of the ranking, Borna turned the attention to Piatti coaching team, beginning to work under Riccardo Piatti and Kristijan Schneider who traveled with him during tournaments. From 24 ATP wins in 2017, Borna counted to 40 in 2018, improving various elements of his game and lifting the ATP 500 trophy in Halle after beating Roger Federer in the final.
Borna was the semi-finalist at Indian Wells, losing to Federer in three tight sets before the quarter-final run in Miami, earning valuable points and cracking the top-30. The results were not there during the clay season, forcing Borna to step down to the lower position on the ATP list before that incredible result in Halle that pushed him into the top-20 for the first time in a career.
After early exits in the next couple of events, Borna reached the fourth round at the US Open and won two Davis Cup rubbers against the USA, helping his country to reach the final where he grabbed one win en route to the title.
Before that, the young Croat went all the way to reach the final at the Masters 1000 event in Shanghai, toppling Juan Martin del Potro and Roger Federer before losing to Novak Djokovic, securing the spot in the top-15 and setting eyes on big achievements in 2019 as well.
Coric advanced into the fourth round at the Australian Open and the semi-final in Dubai, followed by the quarter-final run in Miami, Monte Carlo and Budapest, failing to repeat what he had don in Halle last year and struggling to find the form in the last couple of events.
Borna was forced to skip Wimbledon with back problems and couldn't find the form in Umag, Montreal and Cincinnati as well before another withdrawal at the US Open ahead of the second-round clash with Grigor Dimitrov. After that, Borna has decided to part ways with Piatti coaching staff after almost two years, seeking new solutions and hoping to play on a high level again in the rest of the season, with 780 points to defend from 2018 if he wants to keep the current ranking position and maybe fight for the place in the top-10.
"I have decided to split ways with Piatti tennis center after having some great times on and off the court. I'm thankful to Riccardo for all of the things I learned from him, wishing him all the best with current and future projects.
Dalibor, thank you for all of the workouts we did together and keeping me ready for all those three-setters. Claudio, thank you for taking care of my body and for being a part-time photographer during our trips, I wish you all the best guys.
After a few days off, I will soon be ready to get going again, eager to finish the season on a high note. Thank you for all the support you have been sending me."
