In March Kubot with his doubles partner Marcelo Melo reached the doubles final at Indian Wells Masters. Eighth seeded Lukasz Kubot and Marcelo Melo reached the BNP Paribas Open semi-finals after breezing past tricky wild card duo, Nick Kyrgios and Nenad Zimonjić. The Polish-Brazilian pair then defeated fourth seeds Jamie Murray and Bruno Soares to reach the final against the 6th seeds, South Africa's Raven Klaasen and his American doubles partner, Rajeev Ram. At the 2017 Miami Open Kubot and Melo dropped only three sets en route to the final, defeating Marcus Daniell & Marcelo Demoliner, Jean-Julien Rojer & Horia Tecău, Jamie Murray & Bruno Soares in QF and Daniel Nestor & Brian Baker in SF to reach their second straight ATP Masters 1000 final. The sixth-seeded Kubot and Melo defeated American duo Nick Monroe and Jack Sock in straight sets. They made it all the way together at an ATP event for the first time this season. It was their first ever Masters 1000 title won as a team as well. Kubot and Melo have continued their streak of claiming at least one ATP doubles title together in a season for the third straight year. They're back-to-back Vienna doubles champions, having won the tournament together in 2015 and 2016. Miami Open was their 11th career tournament together, with a current overall 22–8 record and 12–6 record in 2017.
