With Tiger Woods still in absentia attempting to salvage his career, Matt Every did his best imitauion of the former world number one player, holing an 18-foot birdie putt on Bay Hill's famed 18th hole to successfully defend his 2014 title at the Arnold Palmer Invitational.  Every lingered around the lead throughout the week but seldom looked like he'd emerge with the trophy, largely because of the hot form of current world number three Henrik Stenson, who pieced together rounds of 68-66-66 to enter Sunday's finale two ahead of Morgan Hoffmann and three up on a quartet of players which included Every.  But Stenson would only turn in 35, and with Every bogeying the par-4 1st, it was left to Hoffmann to sprint out early - a feat he accomplished by birdieing five of his first eight holes en route to turning in 32.  Every, meanwhile, bounced back with four outgoing birdies to turn in 33, then added two more at the 10th and 11th to reach 18 under par.  By this time Hoffman, a third-year player seeking his maiden victory, was fading, bogeying the 12th (a par 5) and 13th to fall back to 16 under par.  Stenson, meanwhile, made the sort of move that one might expect off him, birdieing the 11th and 12th to re-take control on 19 under.  But after having his group put on the clock, he promptly three-putted for bogey at the 15th, then three-putted for par at the three-shot 16th - and just like that, he and Every were tied.  And in the the end, it was the two men's respective putters that sealed the deal, as Every coolly holed his biridie effort at the last, while Stenson missed a 15-footer wide left that would have forced a playoff.................. Continuing the good form that saw him claim his second Sunshine Tour victory at November's Lion of Africa Cape Town Open, Jaco Ahlers survived a three-hole playoff to defeat Jaco Van Zyl at the limited-field Investec Cup, and thus pocketed the year-long competition's R3.5 million bonus pool prize in the process.  In a field determined by an accumulated points system - and which was strong enough to include world number 33 Charl Schwaertzel - both Ahlers and 13-time Sunshine Tour winner Van Zyl began Sunday's final round at the Lost City Golf Club four shots behind another established international star, George Coetzee, before closing with fine 66s, Van Zyl by birdieing four of his last five holes.  With Coetzee stumbling home with a 71, that left the two Jacos to go to extra holes, a playoff which would require three trips over the watery par-5 18th.  On the third playing, both men found water off the tee but Ahlers, playing safely, laid up his third, then wedged to within six feet to save par.  Van Zyl, meanwhile, found water a second time, with the resulting bogey handing Ahlers the title.
