Playing only 35 minutes from his home, San Antonio resident Jimmy Walker tamed both a strong field and a stronger golf course to become the PGA Tour’s first multi-time winner of 2015, holding off a late-charging Jordan Spieth to claim the Valero Texas Open.  On a TPC San Antonio layout whose scoring average (74.581) was the highest of the year to date, Walker opened with a 71 to trail Charley Hoffman by four and Aaron Baddeley by three – Baddeley’s round finding a page in the history books for his play at the 336-yard 17th, wherein he hit his tee ball into an unplayable lie, marched all the way back to the tee to play his third, then promptly holed a full driver for birdie.  On a less-windy Friday, Walker carded a near-flawless 67 to nose into the halfway lead, standing one ahead of both Hoffman and Baddeley.  But it was on Saturday that Walker took command, playing his first 12 holes even par before logging late birdies at the 14th, the 17th and the 18th to post a 69, good enough to move four ahead of Spieth (who double-bogeyed the par-3 16th en route to a 71) and six up on Billy Horschel, who birdied the last three holes to shoot 69.  With Spieth turning in one-over-par 37 on Sunday, Walker’s lead ballooned as high as seven shots, and while the 21-year-old Spieth would mount a spirited charge via four straight birdies at holes 14-17, Walker carded clutch birdies of his own at the 16t h and 17t h, effectively slamming the door and giving him a four-stroke margin of victory…………………Thirty-one-year-old Scot Richie Ramsay won for the third time on the European PGA Tour, recovering from some mid-round Sunday stumbles to log a one-shot victory over France’s Romain Wattel at the Trophée Hassan II.  The 2006 U.S. Amateur champion, Ramsay began his week quietly, trailing first round leader Adrien Saddier by seven after carding an even-par 72.  But with Saddier stumbling to a Friday 77, Ramsay perhaps unexpectedly found himself in a four-way tie for the halfway lead (with Richard Green, Oliver Farr and Rafael Cabrera-Bello) after posting a bogey-free 66, then remained among the threesome that topped the third round leaderboad (a group which included Wattell and Andrew McArthur) upon adding an up-and-down 71.  McArthur, for his part, would play himself out of contention early, his eventual 77 anchored by a triple-bogey at the 200-yard 8th.  Thus while a quintet of players would get into the clubhouse on eight-under-par 280 before them, the battle would ultimately come down to Ramsay and Wattell, with the former jumping out to a three-shot lead after recording four straight birdies at holes 4-7, then falling two behind after bogeying the 368-yard 7th, then matching McArthur’s six at the short 8th.  But Ramsay eventually drew himself even with birdies at the 12th and 13th, then jumped two ahead with a birdie at the 14th as Wattel made bogey.  A Wattel birdie at the par-5 17th closed the margin to one, and that was how it ended.
