Great match, too good for a 500 QF. Berdych has been in form lately and is looking to win the title here. Kei's form has been more irregular, but he has a future top 10 too and has posted wins over top players.
Nishikori played awesome in their last hard court match in Basel last year, don't think he'll play that well here though. Going with Berdych in 3, stats of his match vs Falla today are amazing too, seems to be playing well.
