Really 6-2 6-2 6-2 in Melbourne and 6-4 6-1 in Rome ! The first sounds like a thorough Thrashing to me ! 2nd is pretty comprehensive as well ! He,s never won a set off Rafa ! Nadal without getting out of first gear !
Granted, the first encounter was a trashing but other than that: lots of matches like today where Nadal wins a close & lenghty first set due to one (more) break. I mean, just what do you understand by obliterate? cf. obliterate 1. To remove completely, leaving no trace; to wipe out; to destroy.
