Justin Rose surged into a four-shot lead at the halfway point of the Farmers Insurance Open as he seeks a second victory at Torrey Pines. The 45-year-old Englishman added a seven-under 65 on the tougher South Course to his opening 62 over the North Course to sign for a 17-under-par total. After dropping a shot on the 12th, Rose added further birdies at the 13th, 17th and the last to pull four clear of Ireland’s Seamus Power. Power carded a 66 to reach 13 under, with Americans Joel Dahmen and Max McGreevy sharing third on 11 under. Brooks Koepka extended his return to the PGA Tour by making the cut on three under after improving on his opening round by five shots with a 68.
