Perhaps it says something about the nature of the FedEx Cup Playoffs that their 2014 champion, Billy Horschel, logged but a single top 10 PGA Tour finish from January through August, making him the biggest longshot winner in the Playoffs’ history.  On the other hand, after a chunked 72nd-hole 4 iron cost him a chance at the Deutsche Bank Championship (where he finished second), Horschel won the final two FedEx Cup events in succession and, lest there still be doubters, closed out his Tour Championship victory by playing head-to-head with world number one Rory McIlroy over the final 36 holes.  And while McIlroy seemed to be running on fumes after a long summer of spectacular golf, Horschel was just reaching cruising speed at Eastlake, putting together four impressively steady rounds to roll to a three-shot victory.  He grabbed a share of the first round lead (with Chris Kirk) by posting a bogey-free four-under-par 66, then matched that (despite two bogeys) on Friday to take a two-shot halfway lead over McIlroy, Kirk and the recently hot Jason Day.  Seemingly unfazed by the first of his two pairings with McIlroy, Horschel turned in three-under-par 32 on Saturday, but just as his lead began to look imposing, he bogeyed both the 10th and 13th which, combined with McIlroy eagling the par-5 15th en route to a 67, left the pair tied atop the leaderboard after 54 holes, two ahead of Furyk, who posted a 67 of his own.  With birdies at the 4th and 5th, Horschel nosed one ahead in Sunday's early going before McIlroy seemed to abruptly run out of gas, double-bogeying the par-3 6th with a tee shot in the water, then spinning out entirely with bogeys at the 9th, 10th and 11th.  He would eventually recover with birdies at the 15th, 16th and 17th, just as Furyk would mount a late charge by birdieing the 12th, 13th and 16th.  But in the end, Horschel played steady, even-par golf on the inward half to comfortably claim both his third PGA Tour win and the $10 million top prize for clinching the FedEx Cup...................Some pretty long odds might have been obtained by anyone wishing to wager on Paul Casey's chances of winning the KLM Open had their bet been placed on Friday night, as the 37-year-old Englishman, making his first competitive start since becoming a father, stood tied for 32nd, eight shots behind halfway leader Pablo Larrazabal.  Indeed, Casey was far enough in arrears that he actually started on the 10th tee on Saturday - but he wasted little time thereafter lifting himself back into the fray, carding five back nine birdies (including on all three of the loop's par 3s) to turn in 29, then adding four more on the front side to reach the 9th at nine under par.  Remarkably, his approach at the 418-yard par 4 nearly went in the hole (which would have meant shooting 59) before spinning back off the green, leading to an unlucky bogey and a round of 62 - good enough to stand alone in third, but still four shots behind 54-hole leader Romain Wattel.  But Wattel would stumble to a 74 on Sunday, paving the way for Casey (who closed with 66, but left the door slightly ajar with an untimely bogey at the par-3 15th) to win by one when three-time KLM winner Simon Dyson could manufacture only one birdie over the final four holes in attempts at catching him..................Thailand's Prom Meesawat won for the second time on the Asian Tour, getting some late help from touted Philippine prospect Migual Tabuena before defeating Tabuena in a playoff at the Yeangder Tournament Players Championship.  Initially, this looked like it might be the 19-year-old Tabuena's breathrough week, particularly after he followed up a disappointing opening 73 with a bogey-free 68 on Friday and an even better 65 on Saturday, a near-flawless round which included a back nine 30 and left him with a one-shot 54-hole lead.  Two early bogeys on Sunday quickly took Tabuena out of the top spot but he rallied gamely, carding four birdies between the 9th and 16th to charge back into a one-shot lead.  But staring victory direrctly in the face, the diminutive Tabuena bogeyed the par-3 17th to fall back into a tie with the 30-year-old Meesawat, then lost the playoff by bogeying the par-5 18th, essentially handing Meesawat the title..................Twenty-six-year-old Australian Adam Stephens won for the first time on the Australasian Tour, building a big 54-hole lead before eventually marching home to a five-shot victory at the second playing of the South Pacific Open Championship, in New Caledonia.  Competing against a relatively light field (world number 304 Matthew Griffin was the top-ranked entry), Stephens opened with rounds of 67-64-68 over the undersize Tina Golf Club layout, numbers which somewhat surprisingly lifted him to a five-shot Saturday night lead.  Stephens then three-putt bogeyed the first hole on Sunday, but on a day when his scrambling outpaced his ball-striking, he still managed to turn in 36 before rattling off three birdies between holes 10-14 which effectively secured the title.
