We told you mate, Medvedev is really playing good tennis right now specially in the last two months or so and has the potential to challenge the big three. It will be a interesting to see him facing Djokovic and could pull a upset here because Djokovic is not 100% in this tournament.
Federer in three sets over Evans. Djokovic will be facing Denis Kudla in about three hours.
@vella85 - yup, womens side has its own upsets, but Osaka looks strong but Barty is still up to the challenge.
Yes we could see one of these players beat the big three and we can add another young talent to this list, Alex de Minaur who just had a big win over Nishikori. Alex de Minaur had an amazing US Open last year and it looks like he is going to go far again this year and could be a real danger to the big three. Lets see how Djokovic goes in under an hour from now with he's shoulder and Medvedev is also playing so we got two great matches to look forward to.
