Justin Thomas believes he has underachieved in major championships as he bids to double his tally with victory in the 86th Masters.
Thomas won the US PGA Championship in 2017 and has recorded four other top-10 finishes, but is decidedly unimpressed with his performance in the game's four biggest events.
