NORTON, Mass. – Open champion Henrik Stenson shot the lowest score in major championship history with a slight cartilage tear in his right knee.
Stenson said Thursday that tests revealed the injury that dates to the U.S. Open in June. He had surgery last December, but this tear was in a slightly different spot. He also had cartilage surgery in his left knee in December 2011.
The 40-year-old Swede said his knee problems do not affect his shots, though he feels discomfort walking 18 holes, especially on courses with side slopes.
''We'll just have to wait and see how much potential grief it gives us, if I want to do another procedure or if it's something I can cope with over time,'' Stenson said.
