Rory McIlroy astonished by Charley Hoffman's 'incredible' opening-day

Rory McIlroy will not lack for confidence going into Friday's second round, despite his astonishment at Charley Hoffman's Masters-leading, opening-day 65,
Hoffman, 40, shot a seven-under-par round in the most challenging conditions at Augusta National on Thursday as the American made light of the gusting winds of up to 40 miles per hour to take a four-shot lead into the second day's play.
