Rory McIlroy expressed his satisfaction after keeping his dreams of the career grand slam on track with a battling display on the opening day of the 79th Masters. Seeking to become just the sixth player in history to win all four major titles, McIlroy was one over par after 11 holes before recording birdies on the 13th and 15th to card a one-under-par 71. That left the world No 1 four shots off the clubhouse lead of Justin Rose and Charley Hoffman, but it could have been a lot worse as the 25-year-old was forced to scramble for par a number of times on the front nine.Rory McIlroy .
