US Open 2014: Rory McIlroy ready to grind out Pinehurst pars

Rory McIlroy says he will refrain from attacking flags in this week's US Open at Pinehurst as he aims to repeat his 2011 triumph.

"If you grind out pars here, you are not going to lose any ground to the field," McIlroy tells BBC Sport Northern Ireland's Stephen Watson.

McIlroy also says he has "stuck my head right into golf" following his split with Caroline Wozniacki.

He added: "I've been listening to a lot of music and reading a lot of books."
