ATLANTA – Louis Oosthuizen withdrew from the Tour Championship after 14 holes Thursday with a muscle strain in his right knee.
Oosthuizen said he started to feel “tension” in the knee during the final round last Sunday at the BMW Championship, but had treatment Monday in South Florida and didn’t expect it to be a problem at East Lake.
About seven holes into his opening round, however, he started to feel tightness again and said he decided to stop playing when the ailment began affecting his swing.
“It came back really quickly,” he said.
