I'm a bit late writing this article today to include Britain's Kyle Edmund in the mix, as we speak he is fighting for another Semi Final spot to follow suit of Beijing last week. He's up against it facing Germany's Alexander Zverev who masterfully fending off last weeks Beijing Champion Nikoloz Basilashvili in straight sets before repeating that accomplishment vs new comer Aussie Alex De Minaur. Edmund will be a worthy opponent for Zverev, he's not as wild as Nikoloz Basilashvili preferring to play more conservative off the backhand whilst getting his forehand firing whenever possible to hit the winners. Whether he can overcome Zverev is another matter entirely.

Edmund's Rise in the Rankings

For me Zverev represents Edmund's toughest match so far in his career. The Brit has reached an all time high 14th in the world this year coming up from 50th position and is playing an excellent level of tennis, which is clearly showing results with the amount of ATP points he has managed to collect. In fact he even has an outside chance of qualifying for the ATP Finals in London, that would be an unbelievable achievement for Edmund if he can pull it off. But I don't think he's ready to take on the likes of Zverev yet who although two years younger than Edmund, has already won 9 ATP titles including 3 this year to Edmund's none.

Anderson vs Djokovic: The Laver Cup Rerun

Kevin Anderson is somewhat of a late bloomer in terms of his career progress in going deep into big tournaments. Before 2017 he had never made it to a Grand Slam final in is entire career. Now he has made it to two in two years, unfortunately for him he's faced Nadal and Djokovic respectively. Still making Grand Slam finals is a huge step up for Anderson as well as winning the New York ATP this year defeating both Kei Nishikori and then Sam Querrey in the final.

Anderson may have been overwhelmed by Djokovic at Wimbledon when he lost 3-0 looking complete second best the whole match but that didn't stop him taking revenge on this years Wimbledon and US Open champion when it came to representing Team World at the Laver Cup in Chicago. Anderson produced the sort of tennis there that got him through against Roger Federer in 5 sets at Wimbledon this year. He one two punched Djokovic on serve for the majority of the game whilst also going toe to toe for many of the rallies. But Anderson's serve was the key here, he was so consistently strong for the majority including key points of the match serving 17 aces in 3 sets and winning both of his sets via tie break.

Prediction: Djokovic is likely to prevail here but I am going for the upset again. I managed to watch Anderson defeat the young Greek - Tsitsipas where on serve he again looked unbreakable for most of the two sets. He had a high 72% of first serves in, 83% of which he won whilst serving 10 aces. If he can bring that service game into today's match he has a chance of repeating his Laver Cup exploits.

I am going for a 2 sets to 1 win the for the South African.

Federer vs Kei Nishikori: Swiss in a Different League Even with His Wobbles

Federer is my pick to win this tournament, but the signs thus far haven't been so convincing from the Swiss at times. He has conceded a set in both his matches against Danil Medvedev and Roberto Bautista Agut. Yes both those players are worthy opponents and produced great displays vs Federer but you can also argue that the Swiss star has failed to impose his will on those games for a consistent period of time and the sets he has conceded he looked off the pace.

Federer's serve usually so potent was a little off against Bautista Agut, in fact the Argentinian served more Aces than he did plus Federer was broken twice. Not the signs of someone who can take on Djokovic in the final. Having said that as I have predicted an upset for Djokovic maybe it's going to be a Wimbledon Quarter Final rerun between Federer and Anderson in the final here!

Kei Nishikori is suffering a title drought having not won a tour event since Memphis 2016 which was hardly the most of competitive of tournaments to win. He hasn't in fact won a big tour event since the Washington Open 2015. But he would happily trade most if not all of his 11 titles away for one Grand Slam win. He has only ever reached one Grand Slam final all the way back in 2014 where he lost in straight sets to Marin Cilic.

That is the one failure that has plagued his career thus far and you get the feeling he is desperate to win one for himself and his country. Back in September it was his much younger counterpart Naomi Osaka who lead the way becoming Japan's first ever Grand Slam champion of tennis. Whilst Nishikori would have been delighted for the 20 year old, you can't help feel it may have also hit home on a deeper personal level highlighting his own failures to not claim one for himself at the age of 28.

Right now Nishikori will be focusing on winning a Masters title here and recording his first victory since 2014 against Federer. The Japanese player almost ousted him at last years Australian Open 4th Round where he lost 3-2. He looked resilient against Sam Querrey yesterday - not the easiest of opponents to take down in 2 sets given his reputation for dominance on his serve. I'd like to think in a way Nishikori can kick start his season by defeating Federer here but I just don't think he's got it in him to do so.

One major weakness for Nishikori is his serve. Standing at just 5ft 10inches his serve is rendered ineffective for the majority of games. Not being able to score cheap points so often off on serve puts a huge pressure on your open play game which doesn't always fire no matter who you are. Federer will likely eat Nishikori's service game alive.

Prediction: Federer will win this one, a correct score is a tough one to call as I feel Nishikori could take a set off Federer as he has been wobbling this tournament and looking a bit fragile. But I am going to stick to my guns with another prediction of Federer winning in straight sets - 2-0.
