AUGUSTA, Ga. -- PGA champion Jimmy Walker says he has been coping with mononucleosis that has contributed to his lethargic play.
Walker captured his first major last year with a wire-to-wire victory in the PGA Championship, contended in the second FedEx Cup playoff event and went 1-2 in his matches at Hazeltine when the United States won the Ryder Cup.
He has spent most of this year trying to figure out why he has felt so sluggish and finally was diagnosed with mono.
"I haven't passed it on to the kids or to (wife) Erin, so that's good," Walker said.
