 Carlos Alcarez vs. Alexander Zverev is a fourth quarter final for the men's US Open for 2023. And both guys have had different roads to get to this stage. Zverev entered the tournament as the number 12 seed and will take on Vukic in the first round. This is no problem getting through in straights 6-4, 6-4, 6-4. In the second round he take on Altmaier and after splitting the first two sets he would fight back to win 7-6-3, 6-6-4, 6-3. In the third round he take on Dimitrov the 19th seed and after dropping the first set he had to save set points in the second eventually getting through in four 6-7, 7-6, 6-1, 6-1. In the fourth round he take on the number 6 seed Sinner who had just taken out Vavrenko in the previous round and this was a bang up with both guys splitting the first two sets. Sinner cramping in the third and Zverev having to push to the fifth. Zverev would eventually get through in over four and a half hours 6-4, 3-6, 6-2, 4-6, 6-3 to advance to the quarter finals. Alcarez enter the tournament as the number one seed and will take on Kopfer in the first round. But after the first set Kopfer would have to retire injured giving Alcarez the win 6-2, 3-2, retirement. In the second round he take on Harris and after a close third set Alcarez would get through in straights 6-3, 6-1, 7-6. In the third round he take on the 20-60 Dan Evans a man that he'd beaten earlier in the year. But after dropping the third set Alcarez would fight back to win 6-2, 6-3, 4-6, 6-3. In the fourth round he take on Anoudi who had taken out Nori in the previous round but the experience of Alcarez was too good getting through in straights 6-3, 6-3, 6-4 to advance to another US Open Quarter Final. These two guys have played five times of four with Zverev actually leading the head to 3-2. However Carlos has won two of their last three matches but those were all on clay courts. Zverev has won their only two hard court matches back in 2021. If Zverev is going to win this one he needs to serve big. He serves so well at times against Sinner and really pushed him to the brink. However he is going to be physically tired so we're going to see pretty early on whether or not he can be aggressive early he's going to have to win that first set if he is going to take something out of Alcarez. If Alcarez is going to win this one he needs to drag the rallies out. The longer this match goes on it feels like the better for Alcarez because Zverev of course is coming off a four and a half hour epic and Alcarez is on a pretty easy road to this stage so he's going to have to drag out the rallies and really makes Zverev move and work those legs. This is an interesting matchup because of course we've seen them play three times in the last you know 18 months on a clay court. We haven't seen them play on a hard court for a while especially this Alcarez against this Zverev but I have to go with Alcarez in four. I think Zverev might be able to get a set but Alcarez is just too good at the moment and it's Zverev had a great win over Sinner but I don't know how much he has left in the tank so I'm going to go with Alcarez in four to make the semis but let me know down in the comments below who's going to make the semifinals.
