Video: 'Not so tough now' - Bubba Watson shoots down heckler who targeted Rickie Fowler
Two-time Masters champion Bubba Watson leapt to the defence of his Ryder Cup team mate Rickie Fowler after he was targeted by a heckler during the Memorial tournament in Dublin, Ohio.
Rickie Fowler missed a putt for par on the 18th to sign off on a disappointed first round 75 and was mocked by a member of the crowd.
His playing partner Watson immediately responded: 'Who said it"
When a response wasn't forthcoming, he added: "Not so tough now are you?"
That member of the public was wise to pipe down.
