Twenty-one-year old American Jordan Spieth may have surprised American viewers by not winning on the PGA Tour during 2014, but he certainly ended the year in style, sprinting to a runaway six-shot victory at the Australian Open.  Spieth’s victory was made all the more impressive by the manner in which he did it, posting a dazzling Sunday 63 (which beat the field by fully three shots) to break open a tournament whose scoring was consistently high due to fast greens and steady breezes.  Spieth began the final round tied atop the leaderboard with Australians Greg Chalmers and Brett Rumford, one stroke ahead of Rod Pampling and world number three Adam Scott.  But while most of the field struggled to make final round birdies, Spieth reeled off eight of them, carding four on the outward half at the 3rd, 5th, 6th and 7th.  Now staked to a multi-shot lead, he padded his margin with additional birdies at the 14th and 15th, then ran away and hid by adding two more at the 17th and the par-5 18th.  It was the sort of round that generates a buzz – such as a Tweet from world number one Rory McIlroy, who said simply: “You could give me another 100 rounds today at The Australian and I wouldn't sniff 63.  Congratulations Jordan Spieth.”………………In an up-and-down week that twice saw him twice fail to break 70 while also posting the event’s two lowest rounds, Shingo Katayama claimed his 28th career Japan Tour title at the Casio World Open, in Kochi.  The 41-year-old Katayama, who last won at the 2013 Tokai Classic, stood tied for 28th after opening with a 70, then pushed into the halfway lead on Friday behind a bogey-free eight-under-par 64.  But such strong form deserted him on Saturday, when he stood two over par through 13 holes before birdies at the 15th and 18th brought him home in 72, leaving him tied for second, one shot behind Satoshi Kodaira, Shugo Imahira and Yasuki Hiramoto.  Not one of these tri-leaders would break 70 on Sunday, however – though in the end the point might have moot as Katayama  came loaded for bear.  Indeed, after turning in two-under-par 34, he ran off four straight birdies at holes 12-15 to pull clear, then added a final birdie at the 530-yard finisher to give him a three-stroke margin of victory.  Satoshi Tomiyama, who closed in 67, took solo second, with the rest of the field no closer than six off Katayama’s 271 aggregate………………In one of the more memorable finishes of the 2014 season in South Africa, 32-year-old veteran Jaco Ahlers broke through for his second careerSunshine Tour victory, winning a three-way playoff at the Lion of Africa Cape Town Open.  After opening with steadily improving rounds of 71-69-68, Ahlers began Sunday’s final round four shots behind co-54-hole leaders Hennie Otto and Danie van Tonder, and on a day which saw the wind pick up during the afternoon, he started slowly, bogeying the long par-4 3rd.  But a run of three straight birdies at holes 5-7, then one more at the short par-4 10th, got him going, and he would eventually come home in 68, for a 276 aggregate.  This total was matched by England’s Ross McGowan (who also closed with a pair of 68s) as well as Otto, who struggled with his putter all day before holing a 15-foot birdie putt at the last to tie.  Otto would drop out of the payoff by bogeying the 385-yard 18th on its first extra playing, but the hole would be played four more times before matters were settled – and then only because McGowan missed a three-footer on the final go-round………………Less than 12 months after Prayad Marksaeng won the event’s previous playing, Thaworn Wiratchant became the second late-40s Thai star to win the King’s Cup on native soil, claiming his 18th career Asian Tour win by a two-stroke margin.  Wiratchant played some very solid golf throughout the week, opening with rounds of 68-67 to trail halfway leader Anirban Lahiri by three, then added a bogey-free 66 (anchored by five straight birdies at holes 2-6) to narrow the gap to one on Saturday night.  Lahiri would get off to a slow start on Sunday, eventually birdieing the 8th hole to turn in 35, then making two birdies and a bogey coming home to post a 270 aggregate.  That number was matched by Australian Andrew Dodt, a recent qualifier for the 2015 European Tour who charged home with birdies on each of his final three holes to push into contention.  But in the end, Wiratchant’s domination of the front nine again proved the story as he made birdies on five of his first 10 holes, eventually marching home in 67 to claim the trophy.
