AUGUSTA, Georgia - Defending champion Jon Rahm and Grand Slam-seeking Rory McIlroy came into this year's Masters looking to add their names to the history books but the decorated golfers walked away scratching their heads after the final round on Sunday.

Rahm was bidding to become only the fourth player to retain a Masters title while McIlroy was making his 10th attempt at becoming only the sixth player to complete the career Grand Slam of golf's four major titles.
