Justin Rose carves out four-shot lead in San Diego as Brooks Koepka makes cut

Justin Rose shot a seven-under 65 to extend his lead at the Farmers Insurance Open on the PGA Tour. 

The Englishman, 45, shone brightest on day one and was superb once again on Torrey Pines' South Course. 

Rose, who won this tournament in 2019, hit six birdies, one eagle and one bogey on Friday beat the 36-hole record by two shots.

He sits atop the leaderboard on 17-under par, with a chasing pack that includes Seamus Power, Justin Lower, Joel Dahmen and Si Woo Kim. 

His only blemish came at the par-four 12th hole when his approach from a fairway bunker caught the lip and shot straight right into the thick rough. 

Brooks Koepka carded a second-round 68 to make the cut by on the number on his first start on the American circuit since quitting LIV Golf. 

Several big names missed the cut. 

Rose said: "I'm feeling great. Obviously, yeah, that was two special rounds of golf. 

"Today probably even more so just given it's hard to often follow up a low one. 

"Obviously this week you kind of go from the easy course to the tough course but it was really kind of cool to keep momentum up out there. 

"I felt like decision making was spot on in terms of how I managed my game, and obviously every shot was not going to be perfect out there, but when I was in a little bit of trouble, the putter would come through for me or I'd be disciplined."

Pace of play at Torrey Pines over the years has been a problem. 

Last season, on-course CBS analyst Dottie Pepper criticised the group she was following after they took three hours to complete 11 holes. 

Her comments sparked a wide-ranging debate about pace of play on the PGA Tour.  

Rose told reporters his group were put on the clock when they reached the 11th hole. 

"Everything felt uncomfortable actually for sort of an hour, hour and a half," Rose said

"I felt like I weathered that storm of the round where I felt like out of my routine, out of my flow, out of my out of the zone but kind of did a good job of managing my game for that period and obviously the two birdies to finish made it a really strong day."
