HUMBLE, Texas — Brian Davis changed his life last year, and he's finally seeing the adjustments translate to better golf scores.

HUMBLE, Texas — Brian Davis changed his life last year, and he's finally seeing the adjustments translate to better golf scores.

Davis shot a 65 in his second round Friday and shares the lead at 11 under par with Louis Oosthuizen at the rain-delayed Houston Open.

The second round was suspended due to darkness at 7:36 p.m. with 70 players still on the course.

Houston resident Jeff Maggert was at 10 under, but he had eight holes left to play in his second round. Defending champion Phil Mickelson (70), J.B. Holmes (67), Tommy Gainey (67), and Greg Owen (69) finished their second rounds and were two shots behind the leaders at 9 under.

Three-time major champion Ernie Els, who must win to qualify for next week's Masters, was in the group at 5 under after a second-round 69.

Davis played a total of 32 holes on Friday, finishing a first-round 68 and then making seven birdies on his way to his best score of the year.

The 37-year-old Englishman took a hard look at his life late last year after his father, Robert, died of cancer. He changed caddies, hired a sports psychologist and retooled his swing.

"Probably the highlight of the offseason and to this season was taking a look at everything I did on and off the golf course," Davis said. "I think I'm more prepared going forward now this year."

Davis felt recharged at the start of the season, but missed the cut in three of his first four starts. He finally saw signs of improvement when he tied for 47th at the Honda Classic, then tied for 63rd in Puerto Rico the following week.
