Hometown boy Jimmy Walker held his nerve to close out victory at the Valero Texas Open at TPC San Antonio . The Ryder Cup player added to his Sony Open title this season and three PGA Tour victories in 2014 as a closing 70 maintained his four-shot overnight lead . Jordan Spieth was second on seven under , having perhaps left his run too late before finishing with four birdies in the last five holes . Jimmy Walker poses with the Valero Texas Open trophy after recording a four-shot win . Walker took the trophy at his hometown tournament and now has six wins since the start of 2014 . Walker went into his final round with four-shot lead and managed to preserve his advantage . Walker birdied the par-five second when he laid up short of the green , pitched on and holed a straight eight-foot putt - though he gave the shot back at the fourth . Another bogey at the seventh was off-set as he pitched stone-dead from an awkward bunker stance at the next , and he birdied 10 as well before dropping a shot at 12 . Playing partner Spieth made a late bid to exert some pressure with birdies at the 14th - via a 45-foot putt - and 15th and when his tee shot at the showpiece 16th spun back out of the fringe , there was scope for Walker to crack . Instead , the San Antonio resident struck a lovely pin-high tee shot and read the left-to-right break to perfection on the ensuing 16-foot putt . His birdie was matched by Spieth but the four-shot margin remained and despite a poor tee shot , Walker also birdied the penultimate hole with a good putt from 18 feet . Spieth did likewise and both parred the last to leave Walker as the tour 's first repeat winner this season . He told NBC : 'It 's at home and it 's cool , you can feel support of friends , family and fans . It does n't happen often , to win in your home town . 'It played hard today , sometimes it 's hard to make pars . I was n't putting very good but I finally got the putting stroke smoothed out and holed a couple . 'And Jordan ... holy cow ! I 'll be having nightmares about that guy ! ' Spieth 's efforts mean he has now finished in the top seven in eight of his last 10 starts . Walker , meanwhile , is building momentum for the Masters in two weeks ' time and he said : ' I like Augusta . Walker adds the Valero Texas Open to the Sony Open title which he has already won this season . Jordan Spieth finished as runner-up , despite carding four birdies on the last five holes . Spieth said he found it hard to make par at times on the course but was Walker 's closest challenger . 'All this keeps adding momentum and confidence and I 'm excited to go . I 'll head over tomorrow and take another look at it . ' Billy Horschel , the third player in the group , finished third outright at four under . Chesson Hadley birdied the last hole to finish joint fourth with Daniel Summerhays at three under . Several players went into the tournament with hopes of breaking into the world 's top 50 and qualifying for the Masters , but none were able to produce the finish they required .
