I think it's really premature to say we'll see a lot of young players breaking through and win slams in 2015 after only 1 day of ATP Tour. However, I think the signs are clear that we have more young players than ever who can make an impact on tour now than past 10 years or so. Coric, Kokkinakis, Tomic and Ducksworth have all just scored wins over worthy veterans like Hasse, Benneteau, Querrey and Simon. There are others like Thiem and Kyrgios, with more older and already somewhat established group like Nishikori, Dimitrov and Raonic. There are others like Zverev and Jordan Thompson, and I think ATP tour will see some new faces upsetting top 10 players throughout the year in 2015. I think Australian Open will eventually be won by one of the current top 10 players but it would be nice if some new face wins at least 1 slam this year. 2015 should be an exciting transition period.
