Rory McIlroy ended his media silence after another frustrating round, in which he defended his decision to avoid talking to the press.

The 125th U.S. Open rolls on Saturday at a soggy Oakmont Country Club in Oakmont, Pennsylvania.

Sam Burns make a mockery of Oakmont's brutal challenge with a brilliant round to take the US Open lead.
