( CNN ) Jordan Spieth has Rory McIlroy and the world No.1 spot firmly in his sights after winning the Valspar Championship on Sunday . Spieth won a three-way play-off with a 28-foot birdie on the third extra hole to become only the fourth player since 1940 to win twice on the PGA Tour before turning 22 . It is a feat that not even McIlroy mastered with Tiger Woods , Sergio Garcia and Robert Gamez the only players to have achieved that particular accolade in the past 75 years . But it is the Northern Irishman that is within Spieth 's focus heading towards Augusta . `` I like studying the game , being a historian of the game , '' Spieth told the PGA Tour website . `` It 's really cool to have my name go alongside those . `` But right now currently what I 'm really focused on is Rory McIlroy and the No.1 in the world . That 's who everyone is trying to chase . `` That 's our ultimate goal to eventually be the best in the world and this is a great , great stepping stone . But going into the four majors of the year , to have closed one out in this kind of fashion is going to give me a lot of confidence . '' Spieth has long been heralded as the next big thing in golf -- shining in the amateur ranks with two U.S. junior titles and leading last year 's Masters after the third round before eventually finishing tied for second , three shots behind Bubba Watson . On Sunday , he held his nerve at the Innisbrook Resort in Palm Harbor , Florida , to hold on for the victory . He first rescued par on the 16th with a 60-foot bunker shot and needed a 32-foot putt to ensure his place in the playoff , which he duly holed . It was a putt of similar length that ensured a second Tour win to add to his John Deere Classic success in July 2013 , which he also won courtesy of a playoff making him the youngest PGA Tour winner for 82 years at the time .
mark Spieth only the fourth golfer since 1940 to seal two consecutive Tour wins under age of 22 . Golfing 's newest star sets his sights on usurping Rory ##dom as the world 's No.1 . Confidence is high enough into the majors , in which he finished second a year ago .
