SAN DIEGO — Tiger Woods is gone from Torrey Pines, and Phil Mickelson joined him Friday by missing the cut.

In a tournament that quickly lost a big chunk of its star power, Harris English played another bogey-free round for a 6-under 66 on the North Course to build a two-shot lead Friday in the Farmers Insurance Open.

Mickelson, who worked hard to get into shape in the offseason and was as optimistic as ever, was done in by his short game. The best he could managed was a 72 on the North Course, and he missed the cut by two shots.

Woods withdrew after 11 holes Thursday, citing tightness in his lower back.

“My putting is beyond pathetic,” Mickelson said. “And if I can’t get back to the levels of 2013, I’m not sure what I’m going to do. Because this is very frustrating.”

He was in good company leaving early.

Justin Rose, at No. 5 the highest-ranked player at Torrey Pines, also shot 70 on the North and missed the cut.

So did Hideki Matsuyama, who three-putted for par on the closing hole on the South Course to miss by one shot; Jordan Spieth, who needed an eagle on the 18th on the South to make the cut and hit it in the water; and Dustin Johnson, playing for the first time since a six-month break to get professional help for “personal challenges.”
