LOS ANGELES (AP) -- Jason Kokrak made birdie on all the par 5s at Riviera and shot a 7-under 64 to build a one-shot lead over Chez Reavie going into the weekend at the Northern Trust Open.
There was plenty of power at the top besides Kokrak, who has never won on the PGA Tour.
Dustin Johnson had a 66 and Bubba Watson played bogey-free in his round of 68. They were two shots behind. Johnson has been runner-up the last two years. Watson won two years ago.
Rory McIlroy, Adam Scott and Hideki Matsuyama were four behind.
