Beckman had to share the spotlight, however, with 16-year-old amateur Jordan Spieth, who survived the midway cut by three shots and was tied for 22nd place.
The opening round of the tournament was completed early Friday after having been interrupted by rain and lightning Thursday. There was a seven-way tie for the lead when the first round was completed, but Beckman then made nine birdies on the TPC-Las Colinas course.
He is in search of his fourth PGA Tour victory and second this year.
Blake Adams shot a 64 to tie Beckman for the lead at 10-under 130. Jason Day was alone in third at 131 while Steve Elkington and Jeff Overton shared fourth place at 133.
Hot, sultry conditions prevailed Friday and, with a lack of wind, low scores were commonplace. No one shot lower than 66 in the opening round, but there were 11 scores lower than that in the second round.
Spieth, a local high school student who was given a sponsor's exemption to play in the event, put together rounds of 68 and 69 to open the tournament. Among those missing the cut were Vijay Singh, Brad Faxon and Stuart Appleby.
