THOUSAND OAKS, Calif. -- Thanks to back-to-back bogeys by Zach Johnson, Tiger Woods is again in the lead again at Sherwood Country Club.

Woods is 1 under through his first four holes with a birdie and three pars. The lone birdie came on the par-5 second, where Woods found the hazard off the tee but was able to hit out before sticking a wedge shot to a few feet.

Johnson, on the other hand, has struggled the last two holes with a bogey on the par-3 third after missing the green then running his chip shot well past the hole. He then bogeyed the par-4 fourth to drop back to 7 under and one shot back of Woods.

Matt Kuchar, meanwhile, has moved into contention at 5 under after playing his first holes in 2 under.

K.J. Choi is another stroke back at 4 under. Click here for live scores .
