Danny Willett's brother Peter tweets amusing commentary during Masters

The brother of new Masters champion Danny Willett has made headlines of his own by tweeting amusing live commentary during the final round at Augusta National.

On Sunday, Willett took advantage of Jordan Spieth's implosion on the back nine to become the first Englishman in 20 years to win the green jacket with a three-shot triumph.

During the dramatic final day, which included three hole-in-ones, Willett's brother Peter live-tweeted the event and provided some comedy as he mocked Spieth's slow play and expressed pride that he once "shared a bath" with the Masters winner.

Spieth is lining up his putt. If I'm quick I can get a beer, go to the toilet, and paint the spare room b4 he hits it.#TheMasters #bbcgolf

Speechless.

I once punched that kid in the head for hurting my pet rat.

Now look.#bbcgolf #TheMasters
