John Merrick never allowed himself to think about winning at Riviera in Los Angeles.Not when he was a kid attending his local PGA Tour event. Not when he was at UCLA and could play the fabled course. And certainly not late Sunday afternoon in a playoff when he faced a daunting 3-iron shot under a row of eucalyptus trees, and his opponent was in the middle of the fairway with a wedge in his hand.But Merrick hit the perfect shot under the trees on the 18th to escape with par, and he followed with another flawless shot to a skinny section of the 10th green on the second playoff hole to 18 feet. He made another par, and won when Charlie Beljan missed a 5-foot par putt.It was the second straight year the Northern Trust Open was decided in a playoff on the 10th, a diabolical par 4.Fredrik Jacobson missed a 4-foot par putt on the 18th hole that would have put the Swede in a playoff. He wound up with a 69 and tied for third with Charl Schwartzel (70) and third-round leader Bill Haas (73).BrieflyMatch Play: Rory McIlroy will be the No. 1 seed for the Match Play Championship, which begins Wednesday at Dove Mountain, north of Tucson, Ariz., and will face Shane Lowry.
