English grabs 2-shot lead at Torrey Pines

La Jolla, CA ( - Harris English fired a 6-under 66 in Friday's second round and he jumped two strokes clear of the field at the Farmers Insurance Open.

English ended 36 holes at 10-under-par 134. He has two PGA Tour wins to his credit.

Nick Watney, the 2009 champion, fired a 7-under 65 to jump into a share of second place at minus-8. He was joined there by Martin Laird (68) and Jhonattan Vegas (69).

First-round leader Nicholas Thompson stumbled to a 1-over 73 and he dipped into fifth place at 7-under-par 137.

Jason Day (65), Jimmy Walker (66) and Ian Poulter (71) headline a group of 10 players tied for sixth at 6-under-par 138.

For the second straight week, Tiger Woods and Phil Mickelson will not be around for the weekend. Woods withdrew on Thursday with a back injury, while Mickelson managed an even-par 72 on Friday, but finished at plus-4, which was five shots over the cut line.

"It's very frustrating for me right now. I felt really ready to start the year and these first few weeks have been very poor. I feel like I'm hitting the ball tee-to-green quite well, really well, but my putting is beyond pathetic," admitted Mickelson, who missed back-to-back cuts for the first time since 2012. "If I can't get it back to the levels of 2013, I'm not sure what I'm going to do because this is very frustrating."

Play for the first two rounds was spread over the North and South Courses at Torrey Pines. The final two rounds will be played on the South Course.

The first round was completed earlier Friday after fog delays pushed play back on Thursday. There was another 30-minute fog delay on Friday, but the second round was finished on time.

English, who picked up his second tour win at the OHL Classic at Mayakoba in the fall of 2013, opened with a birdie at the par-5 first of the North Course. He reeled off five straight pars from the second.

The 25-year-old dropped in his second birdie of the round at the seventh. He also birdied the par-5 ninth en route to making the turn at minus-7.

English made it two in a row as he also birdied the 10th. After three pars in a row, he converted his fifth birdie of the day on No. 14. English moved to minus-10 as he birdied the par-3 17th. He closed with a par at the last to lead by two.

"It was a lot of fun. Beautiful day out here at Torrey Pines. I got it rolling a little bit today. It's hard to make a lot of birdies on the South Course, but the North, you can tear up a little more. Have a lot more wedges in and I hit some good shots in there close, and made some birdies," English said.

"South Course is a beast. It doesn't give you any room for error. The greens are a little firmer, a little faster. It's so easy to hit an errant shot and make a bogey."

Watney opened with a birdie first and followed with three pars in a row from the second. Back-to-back birdies at five and six pushed him to minus-4.

Around the turn, Watney birdied the 10th. He later birdied the 14th and made it two in a row with a birdie on the 15th. Watney closed his round with a birdie at the last.

Laird played the front nine in even-par with a birdie at the first and a bogey at the sixth. He made eagle at the par-5 14th on the North Course and came right back with a birdie on No. 15. Laird capped his day with a birdie.

Vegas played the back nine first on the North Course and had three pars and a bogey on the 11th in his first four holes. He poured in three straight pars from the 14th and made birdie at 18 en route to making the turn at minus-8. He played the front side in even-par with a pair of birdies and two bogeys.
