 Andre Rublev vs. Hubek Herkac is the second semifinal at the Miami Open for 2021, and both players have had a different road to make it to the semifinals. The number four seed Rublev started his week off with a buy in the first round. In his second round match, he took on Tennis Sangren, destroying him in straight sets 6-1, 6-2. His third round match was against Martin Fucovich, a man that he played many times in the previous month. Again, it was a demolition job, winning in straight sets 6-2, 6-1. In the fourth round, he took on former U.S. Open champion Marin Chilich, and again an impressive display, winning in straight sets 6-4, 6-4. In his quarter final, he took on Young Gun Sebastian Korda, and after a tight first set, he had to fight to get through the second, to eventually win in straight sets 7-5, 7-6. Herkac arrived to the Miami Open as the 26 seed and had a buy in the first round. His second round match was against Kudla, the American, getting through in straight sets 7-6, 6-4. In his third round match, he took on the number six seed, Denyshapov Arlov, but he flipped the script this week, winning in straight sets 6-3, 7-6. In his fourth round, he took on another Canadian, the 12th seed, Milosh Rayonich, and after losing the first set, had to fight to win in tight three setter 4-6, 6-3, 7-6. His quarter final match was his best comeback to date, against the number two seeds to find on City Pass. After going down badly in the first set and a break in the second, Herkac came back to prevail in 3-2, 6-6, 6-4. In Rublev's quarter final against Korda, he hit 15 winners and 13 unforced errors, including five aces, but only converted three out of seven break points. We'll need to improve on that against Herkac. Herkac in his quarter final against City Pass hit 41 winners, and only 35 errors, with 15 of those winners being aces. And he converted three out of eight break points, and he will have to also convert better against Rublev. These two have only played the one time previous back in Rome in 2020, Herkac getting the win, so Herkac has the confidence against Rublev. Rublev is the only semi-finalist yet to lose a set this week, and he is primed to win his first Masters 1000 title, after winning a bunch of ATP 500s. This is a tough semi-final to pick, because Herkac has showed some great form this week, but I'm going to go with Rublev in this one, just based on his consistency over the last 12 months, and especially at this tournament, yet to drop a set, and he seems to like playing against big servers. So I'm going to go with Rublev in this one, let me know down in the comments below. Who do you think is going to win this semi-final?
