Aryna Sabalenka and Elena Rybakina, the two top women's players in the world, will battle it out in a Miami Open semi-final on Thursday after coming through their quarter-final matches, Reuters reported. 

World number one Sabalenka took down American Hailey Baptiste 6-4 6-4 on Wednesday and is looking to complete the coveted 'Sunshine Double' after her triumph in the Indian Wells final over fellow big-hitter Rybakina. 

"It's definitely going to be a battle," Sabalenka said in an on-court interview. "It's always a battle, always a fight, always a challenge."
