By Shrivathsa Sridhar MELBOURNE (Reuters) -Defending champion Aryna Sabalenka and Madison Keys made rocky starts on Thursday but eventually secured contrasting victories to set up a heavy metal Australian Open final showdown that will pit two of the game's big hitters against each other.

Iga Swiatek offered some high praise for Aryna Sabalenka, saying that the Belarusian tennis star basically doesn't have any weaknesses in her game since she is "solid from every position."
