While Danny was winning the Masters yesterday his brother Peter Willett won Twitter

Golfer Danny Willett may have become the first Briton to win the US Masters in two decades but it was his brother who proved the unlikely star of the show.

Peter Willett, from Birmingham, lived every minute from the sidelines as his 28-year-old brother swung into the history books at the Augusta National Golf Club in Georgia.

Live tweeting from the account @P_J_Willett, his running commentary began to trend on Twitter in the UK.

Posting a picture as his brother moved to four under par and to the top of the leaderboard, he tweeted: "Unbelievable, Jeff. I'm not keeping it together. COOOOOMEEEEE ONNNNNN X."

While Danny, from Sheffield in England, continued to hold his nerve, Peter became aware of what a win would mean for him.

"If the boy does what he should, I will be able to say 'I've shared a bath with a Masters winners - brilliant," he said.

Returning to reality, Peter appeared to be looking forward to basking in his new-found limelight with the children at his school.

"When I'm too tired to teach a good lesson tomorrow, and some kid spits at me, I'm just gonna smile and say 'I won Twitter' *drops mic," he said.
