Miami, FL, United States, 23 March 2019 |

Ajla Tomljanovic has scored her biggest win of 2019, ousting No.9 seed Aryna Sabalenka to reach the third round of the Miami Open.

Tomljanovic beat the Belarusian 6-3 6-4 to score her first top-10 win since 2014, when she defeated Agnieszka Radwanska en route to the fourth round at Roland Garros.

Tomljanovic joins countrywomen Ash Barty and Sam Stosur in the last 32; Barty and Stosur won their second-round matches on Thursday in Miami and will go head-to-head for a place in the last 16.

Tomljanovic next plays Anett Kontaveit after the No.21 seed beat Amanda Anisimova, 6-4 in the third set.

Later on Friday, 27th seed Nick Kyrgios opened his Miami account with a straight-sets win over Kazakh qualifier Alexander Bublik.

Kyrgios’ 7-5 6-3 win sets up a meeting in the third round with Serbian Dusan Lajovic, who upset No.5 seed Kei Nishikori in three sets.

“Today I did well and hopefully I continue during the tournament as well,” Kyrgios told Tennis Channel.

Kyrgios now owns an impressive 11-3 record across four visits to Miami.

John Millman, the No.32 seed, was unable to progress to the third round with Kyrgios.

The Queenslander lead Federico Delbonis 5-3 in the final set before eventually going down 7-5 3-6 7-6(2).

Bernard Tomic fell to No.1 Novak Djokovic in a night match on Stadium court.

The Australian broke serve in the fifth game and had two game points to consolidate that break for a 4-2 lead, only for Djokovic to break back.

The top seed dominated the ensuing tiebreak before running away with a 7-6(2) 6-2 victory.

He next faces Delbonis.
