 Alina Rabakina vs. Yelena Osta-Penko is the first quarter final for the ladies Australian Open for 2023. And both ladies have upset big names along the way. In the first round, Rabakina came in as the 22nd seed and will take on Chucky Areto. And after a close first set, she got through in straights, winning through 7-5-6-3. In the second round, she took on the youngster Yuvane, but this was no trouble for Rabakina, getting through easily under an hour, 6-2-6-1. In the third round, she'll take on the 13th seed and last year's finalist, Danielle Collins. And after dropping the second set, she eventually got through in 3-6-2-5-7-6-2. In the fourth round, she took on the number one player in the world, Egas Fiontek, a player that she had beaten in an exhibition only a couple of weeks ago. And after a very close couple of sets, Rabakina got through, taking out the world number one, 6-4-6-4 to advance to her first Australian Open quarter final. Yelena Osta-Penko started the tournament off as the number 17 seed and played just Shremska in the first round. But this wasn't a problem getting through in straights sets, 6-4-6-2. In the second round, she took on the Hungarian Bondare. And this was a very tough match for the first two sets, very close. But Osta-Penko ran away with it in the third, taking it in 3-7-6-5-7-6-love. In the third round, she'll take on Bandol. And again, this posed no problem for Osta-Penko, getting through in straights sets, 6-3-6-love. In the fourth round, she'll take on the number seven seed, Coco Gough. And after a very close first set, Osta-Penko got through in straights sets, causing the upset 7-5-6-3 to advance to the quarter finals. These two have only played twice before with Osta-Penko winning both the matches, but they haven't played for about four years. So it's been a long time since they've played and also since that time, it's been a... Rabakina has become the champion of Wimbledon, and now she's equal on Grand Slam with Osta-Penko. If Rabakina is going to win this one, she needs a serve well. That's something she did great against with Shriyantek. She got through with serves and also got through with great backhands. Her forearm was a little shaky, but the backhand was on point. So the backhand and the serve combination against Osta-Penko is going to work. If Osta-Penko is going to win this one, she needs to be less error-filled. I mean, there was a few errors against Goff, and also a lot of breakpoints on her serve. She gave two Goff. Luckily she saved them, but if she gives that many breakpoints away, she's not going to get through this match. This is a very interesting matchup, because I think a lot of us thought we're going to get Goff taking on Shriyantek, which we've seen a million times before. So this is a little bit of a different matchup, still a champ versus a champ match, but I'm going to go with Rabakina. I think she's going to win this one in very close straights sets. Maybe a tie break or two. Let me know down in the comments below. Who do you think is going to win this quarter-final?
