Australian summer of tennis 2023: Novak Djokovic reaches Adelaide International final despite injury mystery; USA to meet Italy in United Cup final

And that wraps up Wide World of Sports' live blog of another day of the Australian tennis summer.

The team will be back on deck on Sunday to cover more United Cup and Adelaide International action.

Adios.

Novak Djokovic paused to have an injury treated during an Adelaide International victory over Daniil Medvedev on Saturday night, but a series of events that followed cast doubt other whether the Serbian superstar was hurt or acting.

As Djokovic pieced together a 6-3, 6-4 win to set up an Adelaide International final against the USA's Sebastian Korda, set to be played on Sunday night, he departed the court for a brief medical, citing an injury to his left hamstring.

The 21-time grand slam champion also appeared hampered by his hamstring over the remainder of the match, clutching at the tendon and testing his leg's range of motion on a series of occasions.

Novak Djokovic victorious!

The Serbian legend defeats Daniil Medvedev 6-3, 6-4 to reach the Adelaide International final.

He'll meet the USA's Sebastian Korda in the decider tomorrow night.

Djokovic has powered through to the final without dropping a set.

He paused for a medical during the opening set and appeared hampered by his left hamstring throughout the remainder of the match, but Medvedev ribbed him, casting doubt over whether he was actually hurt.

"Thankfully it was nothing too serious," Djokovic said in his on-court interview.

"If it was I wouldn't be able to continue. So, I just tried with some medical timeout, some inflammatories and kind of settled in ... trying to keep the momentum going and don't allow him to break my serve ... the longer the match went the more my hamstring was warmer, I guess, and bothering me less.

"So, hopefully tomorrow (for the final) it will be all fine."

Daniil Medvedev begins making a mockery of Novak Djokovic regarding his medical, suggesting he's not really battling an injury.

Novak Djokovic, despite leaving the court with a hamstring scare, appears to be cruising to victory in his Adelaide International semi-final.

Novak Djokovic has won the first set of his match against Daniil Medvedev 6-3, but not before departing the court due to an injury scare.

Lucia Bronzetti does it! She wins in straight sets, 6-2, 6-3.

"It's a special moment to bring this important point to Italy," Bronzetti said afterwards.

"I'm so excited, I'm so happy right now - I don't have words."

Originally set to play Despina Papamichail, the Greeks pulled a late switch and produced Valentini Grammatikopoulou instead - who had two wins over Bronzetti in the past two years, including in the qualifiers for the 2021 US Open.

"I played against her four time; two I won and two I lost so it's not easy ... I'm proud of myself," she said.

A huge upset in Adelaide!
