World No.2 Iga Swiatek will put her 16-match win streak on the line against four-time major champion Naomi Osaka on Saturday in the final of the Miami Open. It will be the second career meeting between the two stars, who have both steamrolled their way into their first Miami final. 

"I remember playing Iga in Toronto when she was first coming up, and my immediate thought was, 'Wow, this girl is really athletic,'" Osaka told reporters after her semifinal win over Belinda Bencic. "She's sliding all around the place.

"I think it's really amazing to see how far she's come. She's just so motivated. I know when I won Indian Wells I was just really dead, and then they made me play Serena in the first round [in Miami]. I was like, 'Whoa, dude.' It's just incredible to see she's still in this tournament and still fighting, and she's going to be No.1 soon. It's really cool. I think the WTA is definitely doing its thing."
