In what was a quick and significant response to Jordan Spieth’s Masters arrival as a potential rival for the world number one spot, Rory McIlroy claimed his second career World Golf Championship title via a 4 & 2 final round victory over Gary Woodland at the WGC-Cadillac Match Play, in San Francisco.  With the event debuting a new format that required round robin play within 16 groups of four in order to determine 16 knockout round participants, McIlroy was required to win seven straight matches in order to raise the trophy – and, in a WGC first, actually won three separate matches on Sunday as his quarterfinal tilt with Paul Casey had been suspended due to darkness on Saturday evening.  McIlroy initially emerged from a group which included Jason Dufner (whom he beat 5 & 4), Brandt Snedeker (2 up) and Billy Horschel (20th hole) before heating up to rout Hideki Matsuyama 6 & 5 in Saturday morning's round of 16.  Following his overnight victory over Casey (whose extended Saturday play forced him to cancel a planned evening trip to Las Vegas to watch the Floyd Mayweather-Manny Pacquiao fight), McIlroy then vanquished Jim Furyk 1 up in a spirited match in which Furyk repeatedly put on late pressure, only to lose when McIlroy finished birdie-birdie-eagle.  Woodland, meanwhile, emerged from a group which included Jimmy Walker, Webb Simpson and Ian Poulter before beating Marc Leishman 2 & 1 in the round of 16, John Senden 5 & 3 in the quarterfinals, and England's Danny Willett in 3 & 2 in the semis.  But with the exception of a few brief moments early in the back nine, the final was all McIlroy, as he rode three birdies to win four consecutive outbound holes, building up a lead which would eventually prove insurmountable.  Among other notable facts, the win made McIlroy only the third player (after Jack Nicklaus and Tiger Woods) to log 10 PGA Tour victories at age 25....................Forty-two-year-old I.J. Jang recorded his third career victory on the Japan Golf Tour, cruising home to a four-shot triumph at The Crowns, in Aichi Prefecture.  Jang spent most of his week near the top of the field, trailing Kyoung-Hoon Lee by one after opening with a 66, then stood three behind Lee, after posting a Friday 69.  Lee would stumble to a back nine 40 on Saturday, however, and with four birdies over his first 13 holes, Jang found himself out front - at least until late bogeys at the 16th and 18th left him tied for the lead with 28-time Japan Tour winner Shingo Katayama, who bounced back from an opening 72 with rounds of 65-66.  Katayama would falter on Sunday, however, bogeying four of his first seven, and with veterans like Kazuhiro Yamashita, Hideto Tanihara and Tomohiro Kondo charging, things might have gotten exciting.  But instead, Jang steadily recorded three birdies over his first 10 holes Sunday, and steadily pulled away to victory...................Forty-year-old veteran Vaughn Groenewald broke a nine-year victory drought on the Sunshine Tour, cruising home to a four-shot win over a relatively light field at the Zambia Sugar Open.  A two-time winner during a 2006 season which saw him finish a career-high 18th in the Sunshine Order of Merit, Groenewald has since played the journeyman's role, though he did accumulate four runner-up finishes during the interceding years.  But this week in Zambia would prove a different story, even if his being tied for the halfway lead (with rounds of 68-65) was largely overlooked due to a spectacular Friday 62 carded by Andrew Georgiou - a round which beat the field by three shots.  But after holding himself steady with a Saturday 71, then bogeying the par-5 2nd to begin his Sunday round, Groenewald bounced back with birdies at the 3rd and 4th before turning on the jets on the final nine, birdieing the 10th, 13th, 16th and 18th to open up his final margin of victory.  Jean Hugo closed with a 68 to take solo second, while recent Zimbabwe Open champion Dean Burmester claimed third.
