Rough final hole for defending champ Day

IRVING, Texas -- Defending champion Jason Day left the golf course quickly after a disappointing double-bogey on his final hole of the opening round.

“I’m pretty mad at myself right now,’’ said Day, who shot a 2-over 72. “Finishing with a double-bogey was bad.’’

Day, who played the back nine first, made birdies at No. 7 and 8 to get back to even par before the late-round stumble.

He pulled his tee shot left at the 432-yard par-4 ninth and dunked his approach in the hazard right of the green.

“I‘m not going to work on anything today,’’ said Day, a Fort Worth resident. “I‘m going home.’’
