Keegan Bradley shot a 10-under 60 to set a course record at TPC Four Seasons Resort in Irving, Texas, on Day 1 of the 2013 Byron Nelson Championship. He made 10 birdies and an eagle on the par-5 16th hole. Afterwards he said that the "holes looked huge."
Bradley broke the course record by one stroke. His 60 topped his former career best by three strokes and tied Arron Oberholser (2006) and Sam Snead (1957) for the lowest score in the history of the Byron Nelson Championship.
Bradley's score arguably could have even been better. He hit bogey on his first and last holes of the day -- technically pins 10 and 9, respectively. The bogey on No. 10 irked him in particular. Bradley called it "probably one of the easiest holes on the course."
Going into Friday, Bradley holds a three-stroke lead over second-place Charl Schwartzel and a four-stroke lead over Ted Potter Jr., Harris English, and Robert Karlsson. Schwartzel's day was particularly clean. He hit seven birdies -- four on the front nine and three on the back -- and no bogeys.
Last year's Byron Nelson champion Jason Dufner finds himself in some early trouble. He began making eagle and birdie on his first and fourth holes of the day, but then proceeded to shoot 4-over for his next 10 holes. Dufner saved face with a birdie on No. 18, his last hole of the day, but finds himself in a tie for 78th-place at even-par going into the second round.
