IRVING, Texas — Jason Dufner birdied four of the last five holes Friday for a 4-under 66 and a one-stroke lead after the second round of the Byron Nelson Championship.
Dufner capped the round with a 37-foot chip-in at the 429-yard 18th, where he drove wide right and hit an approach that rolled over the green into a swale behind the hole. The winner last month in New Orleans for his first PGA Tour title, Dufner also holed a 35-foot chip at No. 15. He had a 7-under 133 total.
Matt Kuchar, coming off a victory Sunday in The Players Championship, was tied for second with first-round leader Ryan Palmer, Chad Campbell, Pat Perez, Dicky Pride and Marc Leishman. Kuchar shot a 68. Campbell had a 66, Perez shot 67, Pride 68, Leishman 69, and Palmer 70.
Defending champion Keegan Bradley was 5 under after a 68.
Phil Mickelson finished with a double bogey for a 69. He was 1 under.
