 Marina Sabalenka vs. Serana Castello is the fourth quarterfinal for the Ladies Miami Open for 2023. And both ladies are going into the quarterfinal without dropping a set. Castello started the tournament off unseated and would take on the wild card Gomez in the first round. And after a close first set would get through in straights 7-6-6-2. In the second round she'd take on the number 5 seat Garcia who she had beaten last week in Indian Wells. This time the scoreline was even more impressive getting through in straights 6-2-6-3. In the third round she'd take on the qualifier Mukava who had been in very good form the last couple of tournaments. And after a close first set Castello would get through in straights 7-5-6-1. In the fourth round she'd take on Vondrusava who had also been very impressive the last couple of weeks. But again after a close first set Castello would get through in straight sets 7-6-6-4 to advance to the quarterfinals. Sabalenka started the tournament off as a number 2 seat and would get a buy in the first round. In the second round she'd take on Shelby Rogers a player that she'd beaten so many times before and this time was no different but Sabalenka getting the win 6-4-6-3. In the third round she'd take on the 31 seat Buzkova but this was no problem for Sabalenka getting through in straights 6-1-6-2. In the fourth round she'd take on Krijikova the number 16 seed who she had played at the last two big events in Dubai and India Wells with both of those matches going three sets and each player winning one each. But this time Sabalenka destroyed Krijikova 6-3-6-2 to advance to the quarterfinals. These two have actually never crossed paths before which is crazy because they are very experienced on the tour with Kestea being in her 30s and of course Sabalenka being around for a long time. If Kestea is going to win this one she needs to make Sabalenka move and she also needs to get a lot of first serves in. That's something that Krijikova really struggled with. Sabalenka's returns have been crazy this week especially on the second serve returns so Kestea needs to have a high first serve percentage. Sabalenka is going to win this one she needs to keep playing like she's been playing. She's been playing so amazing and that first serve when it goes in she barely loses the point and of course that second serve return that I was speaking about with that Krijikova match she can get second serves she's going to annihilate them so she needs to just serve well and keep holding like she has been. This is going to be very fun to watch because Sabalenka is kind of getting to that pre-Australian open form again and just being in Krijikova massive massive win but Kestea is a bit of a wild card with a bit of an unseated player there but I'm going to go with Sabalenka to win this one in straight sets. I think she's just playing so well right now and I think she'll overwhelm Kestea in their first meeting but let me know down in the comments below who do you think is going to win this match up.
