In a week which saw so much rain that the TPC Four Season Resort’s par-4 14th hole had to be converted to a par 3 of barely 100 yards for the final three rounds, Australian Steven Bowditch won for the second time on the PGA Tour, cruising home to a four-shot triumph at the AT&T Byron Nelson.  Bowditch, an area resident who was married in the resort’s hotel, was a wire-to-wire winner, initially taking control on Thursday when he carded a bogey-free eight-under-par 62 on the full par-70 layout.  But five inches of overnight rain - added to the region’s already downpour-softened ground - changed the complexion of the event, with par being reduced to 69 (the Tour’s first sub-70 par in more than 30 years) and Friday’s second round ultimately not being completed until early Saturday morning.  Bowditch, for his part, played up-and-down golf on Friday, carding a seven-birdie, six-bogey 68 before settling into a much steadier 65 on Saturday that saw him take a two-shot lead over a quintet of pursuers into the sunny and dry finale.  And while two early bogeys might well have derailed his Sunday momentum, the long-hitting Bowditch bounced back with birdies at the 6th and the 8th before marching home in four-under-par 30, the resulting 64 allowing him to win going away............Hosted by world number one Rory McIlroy, and played in Northern Ireland at one of the world’s truly great links, the Dubai Duty Free Irish Open was intended to be a showcase for McIlroy, as well as several top-shelf international stars that his involvement helped to draw.  Instead, with capricious Irish weather greatly affecting play, McIlroy opened with an 80 and was gone by Friday evening, opening the stage for a dramatic finish in which 40-year-old Dane Soren Kjeldsen ended a six-year victory drought to claim his fourth career European Tour title.  Kjeldsen went steadily about his business early on, posting opening rounds of 69-70 before carding six birdies over his first 13 holes on Saturday.  A pair of closing bogeys saw him home in 67, however, but still good enough to take a two-shot lead into Sunday’s finale.  That lead lasted exactly one hole (Kjeldsen bogeying the par-5 1st while playing partner Max Kieffer birdied it), and Kjeldsen then bogeyed the 2nd and double-bogeyed the 8th to turn in in 39.  But with heavy wind and rain buffeting the legendary Royal County Down links, only Eddie Pepperell (69) among the challengers could mount a serious charge.  A three-putt bogey at the 17th dropped Kjledsen into a tie with Pepperell and Bernd Wiesberger, and when he couldn’t birdie the par-5 18t h, it was off to a sudden death.  And sudden it was, as Kjeldsen this time reached the 18th green with a fine 3 wood second, then two-putted for birdie to linch the title.  In addition to Kjeldsen, Pepperell and Tyrell Hatton also earned sopts in July’s Open as top 10 finishers here not already exempt............Forty-six-year-old Taichi Teshima claimed his eighth career Japan Golf Tour victory at the Mizuno Open, and in the process secured a birth in July’s upcoming Open Championship at St Andrews.  Teshima opened his week with steady rounds of 69-69 before moving rapidly up the board with a run of five straight birdies to close out his front nine on Saturday.  Later birdies at the 16th and 17th brought him home in  66, good enouh to tie him with Australian Scott Strange for the 54 hole lead.  Strange would play mostly steady golf on Sunday, standing two under par through 10 holes before a double-bogey at the 12th cooled his momentum.  Teshima, meanwhile, turned in 33 before adding birdies at both the 10th and 11th, opening up a lead big enough to easily withstand bogeys at the 13th and 16th.  Strange, Shinji Tomimura and Tadahiro Takayama joined Teshima in earning Open Championship berths, all  as top 10 finishers not already exempt............Forty-seven-year-old Mardan Mamat of Singapore won his fifth career Asian Tour title, leading wire-to-wire in claiming the inaugural Bangladesh Open, in Dhaka.  Mamat carded six birdies during an opening 66 that tied him for the lead with American Casey O’Toole, then backed that up with a 67, which left him one ahead of Spain’s Carlos Pigem and two up on Finland’s Janne Kaske and Panuphol Pittayarat of Thailand.  These three pursuers all failed to break 70 on Saturday, allowing Mamat to expand his lead to three despite carding his worst round thus far (a 68) – and it was only that close because little-known Khalin Joshi of India fired a smart 65 to move within reach.  Mamat bogeyed the par-4 3rd hole on Sunday but left little to doubt thereafter, bouncing back with birdies at the 5th and 6th, then making one more birdie (at the par-3 12th) on his way to a 69, which was good enough to win by two.
