Well possible. Murray should be the only threat for him on slow HCs and Pics ain't afraid of Muzz, RG '11 showed that. Yeah, slow HC is much better surface for Andy than clay but in his peak form, David should be able to outgrind him on a slow HC.
Unfortunately, Ferrer's form hasn't been as consistent as last year, he can still lose to any player remaining in Miami.
Ferrer should beat Murray on a hard court? Wtf am I reading?
