Matthieu Pavon made an 8-foot putt for a dramatic birdie on No. 18 at Torrey Pines South for a one-shot victory in the Farmers Insurance Open on Saturday that made him the first Frenchman to win on the PGA Tour. Pavon raised his arms in celebration and shouted before hugging his caddie after the putt rolled in as dusk began falling at the municipal course high above the Pacific Ocean. His only birdie on the back nine saved him from a playoff. His final-round 3-under 69 put him at 13 under, one stroke better than Nicolai Hojgaard. Pavon was two shots ahead of Stephan Jaeger, who led after the second and third rounds, and Nicolai Hojgaard and Nate Lashley.
