A YEAR after Serena Williams and Naomi Osaka were both caught up in a whirlwind of conflicting emotions, both will be trying to make history in the US Open final on Saturday.

For Williams, the joy of giving birth for the first time last September was quickly followed by a series of complications that led to multiple lifesaving surgeries.

At the same time, precocious Japanese talent Osaka, who grew up idolising Williams, was left wondering if she would ever make it through to the second week of a major after another early exit at Flushing Meadows.

Twelve months on and the duo will contest a final where the prize on offer will not only be the $US3.8 million winner’s cheque.

For Williams, victory would allow her to tie Australian Margaret Court’s all- time record of 24 grand slam titles.

But standing in her way will be a determined Osaka, eager to become the first Japanese player to win a singles major.
