BETHESDA, Md. -- Tiger Woods wasn't the only one to fall victim to the rough at Merion Golf Club.
Jason Day showed up Thursday at the AT&T National with his right wrist taped after suffering a strain in his hand during the U.S. Open two weeks ago.
"That rough was brutal," Day said prior to his opening round at Congressional. "There's a little bit of pain in my hand."
The Aussie is coming off a runner-up finish at the U.S. Open and is one of the favorites at the AT&T National, where he finished eighth last year. He also finished second here when Congressional hosted the U.S. Open in 2011.
Day carded a 1-under 70 in the first round, making four birdies and three bogeys.
