The 2010 British Amateur champion went fairway-green-two putt on the par-4 18th hole at Lake Karrinyup Country Club to eliminate Ross Fisher, who failed to find the putting surface in regulation and eventually missed an eight-foot par save. The duo completed regulation in 10-under-par 278. Fifty-four-hole leader Brody Ninyette settled for a three-way share of third place two strokes back; the Aussie shot a Sunday 72. “I was nervous, I was shaking but I controlled myself pretty well all day I thought,” said Jeong, who closed with a 69 to Fisher’s 68. “I don’t know what I’ve done to be honest. ... I had played playoffs in mini tour events, but playing with Ross Fisher, he’s one of my heroes. Playing with him in the playoff, it was unbelievable.” Among Jeong’s spoils is an exemption into next week’s WGC-HSBC Champions. The 23-year-old started the week at 1,066th in the Official World Golf Ranking. He’ll now encroach on the top 325 when the next edition is released.
