AO Top 5 Photos, 1/26: Swiatek seals second consecutive comeback to enter first AO semifinal 

Iga Swiatek

The Pole ran down every ball and came up with her best tennis when it counted most to edge Kaia Kanepi 4-6, 7-6 (2), 6-3. She's into her second career major semifinal showing and will take on hard-hitter Danielle Collins.

Stefanos Tsitsipas

The Greek was impressive in his straight-set victory over Jannik Sinner. He's through to his third AO semifinal in four years.

Rain Delays Play

During Stefanos Tsitsipas and Jannik Sinner's quarterfinal bout, a determined rain cloud put a brief halt on their match. The roof was closed and ballpersons quickly dried the court.

Daniil Medvedev

Two sets down and a match point saved, the No. 2 seed said it's not over until it's over against Felix Auger-Aliassime. On the brink of defeat he rose to the occasion and came back to grab a 6-7 (4), 3-6, 7-6 (2), 7-5, 6-4 win.

Matt Ebden and Max Purcell

Nick Kyrgios and Thanasi Kokkinakis aren't the only Aussie duo through to the semis. Ebden and Purcell eliminated No. 10 seeds Wesley Koolhof and Neal Skupski 3-6, 6-4, 7-6 (6). This marks their third consecutive win over a seeded team.
