Sam, Shuai reach Miami doubles final

Sam Stosur and China’s Zhang Shuai are through to the final of the Miami Open after a hard-fought win on Friday night.

The Australian Open champions saw off Chinese sister Hao-ching and Latisha Chan 6-7(6) 7-5 10-5 and will face Indian Wells champions Elise Mertens and Aryna Sabalenka in Sunday’s final.

Mertens and Sabalenka ended Ash Barty’s hopes of doing the double in Miami as she and Victoria Azarenka went down 7-6(6) 7-5.

Barty will now turn her focus to taking on Karolina Pliskova in the singles final on Saturday (04:00 Sunday AEST).

In the second doubles semifinal, Stosur and Zhang let the first set slip from 6-3 in the tiebreak, but levelled from a break down in the second.

Some superb returning from Stosur helped the sixth seeds into a healthy lead in the match tiebreak and the pair clinched victory after almost two hours.

They must now face the in-form Mertens and Sabalenka, who are looking to complete the ‘Sunshine Double’ following their victory in Indian Wells earlier this month.
