 Daniel Medvedev vs John Isner is the second semi-final for the Canadian Open for 2021. Both players have had to fight their way to get into the semi-final stage. John Isner started the tournament off taking on another unseeded player for Kena in the first round and after a close first set Isner would get through in straight 6-4, 6-1. His second round opponent would be the 13th seed Garin and although Garin is more of a clay court player he pushed Isner into 3 with the big American eventually prevailing 4-6, 6-3, 6-4. His third round opponent would be against top 10 player Andre Rublev, the number 4 seed at this event and Isner looked very impressive against Rublev who seemed to struggle with the Isner power with Isner getting through in two tight sets 7-5, 7-6. His quarter-final opponent would be against the 11th seed and Frenchman Gael Montfies and after a very close first set Isner ended up winning in straight sets 7-6, 6-4. Medvedev came into this tournament as the number one seed and would get a buy in the first round. His second round opponent was against Bublik, a player that he's played a lot this year and after Bublik won the first set Medvedev was in a lot of trouble and seemed to be struggling mentally but he pulled himself together eventually prevailing in three sets 4-6, 6-3, 6-4. His third round opponent was against the qualifier Duckworth who had just come off beating Yannick Sinner in the second round. Medvedev was too good on this occasion winning in straight sets 6-2, 6-4. His quarter-final opponent was against the 7th seed and Miami Open champion Hubey Hercatch and after getting destroyed in the first set Medvedev hung on to eventually win in 3, 2-6, 7-6, 7-6. These two have only played the one time before that was at the ATP Cup last year in 2020 with Medvedev getting the pretty easy straight sets win 3-1. If Isner is going to get his first win against Medvedev he's going to have to serve well and he's probably going to have to win a couple of tie breaks. We saw that Medvedev played really well in the tie breaks against Hercatch but Isner's going to have to serve well and take the baseline away from Medvedev, make Medvedev move and make him run around. If Medvedev's going to win this one he just needs to be patient. We know Isner's going to serve aces, he knows that Isner's going to hit big serves and push him around a lot and probably going to get a lot of easy free points. Medvedev just needs to be patient and outrally Isner. We know Isner hasn't got the best movement so that's what he needs to do. He needs to make sure that Isner's on the run and he might get some chances to break if Isner does get tired. This is going to be an interesting one for me because Medvedev did beat Isner pretty easily in their only match up but against who be Hercatch Medvedev looked a little bit shaky, hit a lot of errors as well. So I'm going to go with Medvedev but it's going to be 3 sets I reckon, a few tie breaks as well just like we saw when he played against Hercatch but let me know down in the comments below. Who do you think is going to win this semifinal?
