Since she's firmly entrenched in the New York bubble, Naomi Osaka couldn't be with boyfriend YBN Cordae on his birthday. She still found a way to wish the popular rapper a heartfelt happy birthday before her quarterfinal match against Anett Kontaveit in the Western & Southern Open.

Meanwhile, Elise Mertens had another spectacular day at the office as she posted a 6-1, 6-3 score against Jessica Pegula. The world No. 22 is the first to enter the semifinals. 

These are the Top 5 photos from Wednesday.
