Jerzy Janowicz

At the start of the season Janowicz received a wild card to the 2020 Open de Rennes, returning to the tour for the first time since Bratislava Open in November 2017. He spent the offseason in Tenerife with his coach Gunter Bresnik, working hard on his game and preparing for his long-awaited return. In February Janowicz reached the final at the Teréga Open Pau–Pyrénées in France. In the semifinal he defeated No 1 seed Jiří Veselý before falling to Ernests Gulbis.

At the start of the season Janowicz hired a new coach, former Austrian Davis Cup captain, Günter Bresnik. Before the Australian Open, Janowicz participated at ATP Auckland Open in New Zealand. At the first Grand Slam of the year Janowicz faced seventh seed Marin Čilić in the first round. Both players produced an extraordinarily high level of tennis in the first two sets, with Janowicz hitting 23 winners and just nine unforced errors, while Cilic struck 27 winners and only 15 unforced errors. Janowicz required just a single break of serve late in each set to take a commanding two-set lead, but ultimately Cilic rallied from two sets down to prevail in five sets. Janowicz continued at Australian Open with his doubles partner Marcin Matkowski. The Polish team defeated Fabio Fognini and Fernando Verdasco but lost to the top-seeded French team of Pierre-Hugues Herbert and Nicolas Mahut in the second round.

In the opening match, he lost to Novak Djokovic, but managed to take a set off the defending champion before falling in a competitive match on Arthur Ashe Stadium. "It's never easy to play against Djokovic. It doesn't matter where or when or what shape I'm in," said Janowicz. "I was just trying to play my best tennis. I was actually a little bit unlucky because I had quite a few chances to take the first set."

Janowicz started 2015 season by teaming up with Agnieszka Radwańska to win the Hopman Cup, Poland's first title in the event. Janowicz and Radwanska claimed their first Hopman Cup title after they beat the top-seeded USA team 2–1 in a final mixed doubles match over the Americans Serena Williams and John Isner.

Born in Łódź, Poland he was introduced to tennis at the age of five by his parents. Known for his very powerful serve, he can hit at up to 249 km/h (155 mph) along with strong groundstrokes. Despite never winning an ATP title, Janowicz obtained a career-high world ranking of No. 14 in August 2013.

Janowicz became the first Polish male to reach a Grand Slam semifinal at the 2013 Wimbledon Championships, losing to eventual champion Andy Murray.

Janowicz is currently coached by Günter Bresnik and his strength and conditioning coach is Piotr Grabia.

Janowicz inherits his athleticism and height from his parents, who were both volleyball players. At the age of 10 or 11, his parents sold off their chain of sports stores and apartments to support their son's training, recognizing that he had a future in tennis from a young age. As a junior, Janowicz posted a 59–23 win/loss record and reached a combined ranking of No. 5 in the world in 2008.

In the end, he was forced to miss the tie, and Poland lost to Argentina 3–2. Due to the injury, Janowicz missed both the Masters 1000 events in Indian Wells and Miami. The knee injury was another in a long line of injuries for Janowicz. A back injury initially stopped his climb toward the top of the tennis world in 2013. A foot injury followed in 2014.

In the final, he was defeated by fourth seed David Ferrer, but afterwards said "I've got a lot of confidence right now. I learned if you have big heart and you want to do something amazing and you're going to fight for this, you have a big chance to make it."
