Extra Cup motivation not necessary for Johnson

(Reuters) - American Zach Johnson says he does not need any extra motivation at this month's Ryder Cup in Scotland where the United States will bid to improve on a dismal record of seven losses to Europe in the last nine editions.

The last time the teams met, in what became known as the 'Meltdown at Medinah' in 2012, the Americans threw away a commanding four-point lead going into the last-day singles to lose by 14-1/2 points to 13-1/2.
