CHASKA, Minn. — An American heckler upstaged pro golfers during a practice round at the Ryder Cup in Minnesota on Thursday. Rory McIlroy and Henrik Stenson were having trouble making a 12-foot practice putt. They missed six times each, USA Today reported. Fan David Johnson, of North Dakota, yelled out that even he could make that putt, USA Today said. Stenson brought him onto the green and gave him a putter. Another golfer, Justin Rose, put $100 on Johnson’s shot. Johnson nailed the shot and pumped his fists in the air.
