Roberto Castro posted his lowest career PGA Tour score with a 10-under-par 62 on Thursday to take the first-round lead in the Sanderson Farms Championship in Jackson, Miss.
On a Country Club of Jackson course softened by rain and nearly void of wind, Castro took advantage of the conditions with 10 birdies, including five on each nine.
Nine of the 131 players in the field were still on the course when play was suspended for the day because of darkness.
Of the 122 finishers, 103 posted scores of par or lower. None were better than the 30-year-old Castro.
"It's just so soft out there," Castro said. "It's a great golf course, but when the conditions are soft, the scores are going to be low."
Castro has never won on the PGA Tour in more than 100 career starts.
Baddeley has three wins, but his last victory came in 2011 and he has limited tour status. His round was buoyed by a 5-under start through seven holes that included an eagle chip-in from 35 yards on No. 15.
Molder also got off to a fast start. He was 7 under through 10 holes and 1 under the rest of the way.
Rain is in the forecast for the second round on Friday.
