Rory McIlroy's unhappy about US Open rough but can he win it?

Rory McIlroy has expressed his dismay at the decision of tournament organisers to cut down heavy rough on four holes at Erin Hills ahead of the US Open.
Tall fescue grass on the fourth, 12th, 14th and 18th holes was being cut as McIlroy gave his pre-tournament press conference, which caught the 2011 champion by surprise.
