Unheralded Adam Schenk birdied eight holes in a row to share the lead with top-ranked Jon Rahm and Justin Thomas after Thursday’s second round of The Farmers Insurance Open. A day after his 30th birthday, Schenk torched the North Course at Torrey Pines for a career-low 62, 10-under par, to stand on 13-under alongside fellow American Thomas and Rahm, who won last year’s US Open on Torrey’s South Course. It was a good day too for Si Woo Kim, who got himself back into contention with an 8-under 64. The South Korean rattled in seven birdies and an eagle on the North Course to move himself to 9-under at the halfway stage. Kim has had a consistent if unspectacular 2021-22 PGA Tour season, enjoying five top-25s and missing only a single cut in six starts so far. He finished tied for 11th in his title defence at The American Express last week. “Everything went pretty well today,” he said. “With a birdie on the first hole, it gave me momentum until the end. I was confident after that first birdie. I was not anxious and ended with a decent score.” The day though belonged to Schenk, whose birdie run was largely down to his hot putter. His streak began at the par-4 fourth and included a 30-footer at the par-5 fifth, a 40-footer at the par-3 eighth, a 35-footer to begin the back nine and a 30-footer from off the 11th green. “Unbelievable day,” Schenk said. “I didn’t know how many I made in a row. I knew I needed to capitalise while I was playing good golf and that’s what I tried to do. “I lost track of how many I made,” he said. “I knew there were a lot of gettable holes and I needed to keep going if I wanted to get on top of the leader board and hopefully stay there throughout the weekend. I had to try to keep the pedal down and not get satisfied.” This close to tying the course record (61) @FarmersInsOpen . 😫 pic.twitter.com/AQ0sK40g0Y — PGA TOUR (@PGATOUR) January 27, 2022 Schenk finished one shy of the US PGA record birdie streak set by Mark Calcavecchia at the 2009 Canadian Open and matched in 2019 by Kevin Chappell at Greenbrier. Kim’s compatriot Sungjae Im put in a solid performance for his 66 on the more difficult South Course, and moved into a tie for 12th on 8-under. Although too far back to challenge for the top spots, Im is hunting a first top-10 at Torrey Pines in his fourth start. Taiwan’s CT Pan and Japan’s Masters champion Hideki Matsuyama will enter the final two rounds on 5-under after rounds of 72 (South Course) and 67 (North Course) respectively, while India’s Anirban Lahiri enjoyed a bogey free 70 on the South Course to finish on the cut line at 3-under. However, Kevin Yu missed the cut after a 4-over 76 dropped him to 3-over for the tournament. Pan’s fellow countryman started badly with a bogey on the first, which came after he found sand with his drive and second shot. That was the start of a front nine that included three more bogeys and two birdies. Two-over at the turn, any hope Yu might have had of making the weekend evaporated on the par-4 12th, where he found trouble off the tee and eventually finished with a triple-bogey 7.
