McGladrey Classic (and first-time) winner Tommy Gainey comes quickly to mind this week, for even in an era of unchecked equipment, it’s not often that a PGA Tour player cards a final round 60, nor that someone beats a Sunday field by three full shots – and, were it not for David Toms’ 63, the margin would have been an almost unthinkable five.  Beyond routing the field’s average score by more than nine strokes, adding to the round’s considerable shock value is the fact that Gainey had been playing largely mediocre golf in 2012, having logged but a single top 10 (a 3rd-place finish at Colonial, back in May) and never bettering 31st since tying for 13th at July’s John Deere Classic.  But after opening with solid-but-unspectacular rounds of 69-67-68, the former Big Break champion made four front nine birdies to go out in 31 on Sunday, then logged four birdies and an eagle from the 11th to the 16th holes en route to an incoming 29.  A missed 20-foot birdie putt at the last deprived Gainey of a record-tying 59, but as par for the Sea Island Resort’s Seaside Course is only 70, such an 11-under-par total would be marked with an asterisk anyway……………Bo Van Pelt joined Gainey as American major tour winners this week, carding a 272 aggregate to claim the European circuit’s inaugural ISPS Handa Perth International.  Clearly comfortable competing on faraway foreign soil (he is also defending champion at this week’s PGA Tour semi-sanctioned CIMB Classic in Malaysia), Van Pelt’s 16-under-par total was enough to beat Jason Dufner by two at the highly thought of Lake Karrinyup Golf Club – a rare daily double in that Van Pelt and Dufner were the only Americans in the field……………Also notable were a pair of victories logged by the old but not-so-infirmed: 44-year-old Toru Taniguchi’s triumph at the Japan Tour’s Bridgestone Open and 45-year-old Thaworn Wiratchant’s victory at the Asian Tour’s Hero Indian Open.  In Taniguchi’s case, a closing 66 was enough to edge Hiroyuki Fujita by one, allowing Taniguchi to successfully defend his 2011 Bridgestone title, to claim the event for a third time overall, and to log his 19th career Japan Tour triumph.  Meanwhile in India, Wiratchant closed with rounds of 67-66 to post a 270 total, then edged Scotland’s Richie Ramsay on the first hole of sudden death to claim his third Asian victory of 2012 and his 15th overall.
