The classic caddie job description - "Show up, keep up, shut up" - seems pretty cut and dried. But to judge from an incident involving a caddie for Edoardo Molinari on Friday, further explanation may be needed.
As in, "If you can't keep up, do not try to catch up by taking a ride in a golf cart - especially without giving your player a heads up."
According to a tweet by Molinari, the Italian golfer was disqualified from the European Tour's Shenzhen International in China on Friday because he failed to call a penalty on himself after his caddie hopped on a cart between the ninth and 10th holes.
