Sore back no obstacle for Woods in clinching Presidents Cup

Tiger Woods ignored an aching back at the end of a marathon golf weekend on Sunday to clinch a dramatic Presidents Cup victory for the United States over the Internationals.

The 14-time major champion scored the clinching point in an 18 1/2 -15 1/2 triumph by edging South African Richard Sterne 1-up in singles at rain-soaked Muirfield Village, then said he has had enough of golf for a while.
