McIlroy's Masters threeball revealed as Scheffler paired with MacIntyre

Rory McIlroy has been grouped alongside Cameron Young and amateur Mason Howell for the first two rounds of his title defence at The Masters.

The world No 2 completed the career Grand Slam with last year's dramatic play-off win at Augusta National and is now looking to become just the fourth player in history to win back-to-back editions of The Masters.
