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.
Kei leads the H2H 2-1, 2-0 on hardcourts.
Nishikori has only reached the QF twice in his entire career in a bigger event.
Berdych in straight sets. If he is playing well he will win. Kei is solid baseliner, playing fast tennis, good top 20, but if Tomas will play good he will outplay him, outhim him - courts are supossed to be pretty quick here, so his powerfull groundstrokes and big serve should be enough to hit through Kei and overpower him in rallies.
