( CNN ) -- American golfer Nick Watney produced a fine closing round at the WGC-Cadillac Championship in Florida to secure the third PGA Tour win of his career . The 2009 runner-up teed off two shots behind overnight leader Dustin Johnson on the Blue Monster course at Doral on Sunday , but summoned a five-under-par 67 to steal victory away from his compatriot . `` Top-10 finishes are nice , '' Watney told the PGA Tour website after claiming the $ 1.4 million first prize . `` But winning is what counts out here , and that 's how you 're measured . To win this tournament against this field , it 's a huge honor . I 'm very excited . I 'm very proud . '' By the time he arrived at the last , the 29-year-old Watney had opened up a one-shot lead over close friend Johnson -- with whom he shares a coach in Butch Harmon and regular practice rounds . Johnson 's challenge was extinguished when Watney made a birdie at the par-five 18th -- the same hole he had double-bogeyed on Saturday . `` I was n't nervous . I really wanted to take care of business and to grasp this opportunity , '' said Watney , who rose to 15th in the world rankings after his win . `` I actually love that feeling ; you do n't get it too often . `` That 's why you play . I 'm thinking , ' I have to be in this moment -- right now -- because this is all that counts . ' `` Johnson was left to reflect on an opportunity missed , having bogeyed the 16th on his way to a disappointing closing round of 71 . But he was full of praise for Watney . `` Nick is a good friend of mine , '' Johnson said . `` I told him walking off that if I was going to lose to somebody , I was glad it was him . And he played really well . I did n't give him the tournament . He earned it . He played well . '' Tiger Woods produced a stirring final round of 66 to achieve a tie for 10th -- his first top-10 finish in an official PGA Tour event since the 2010 U.S. Open last June . `` I want to win golf tournaments and I did n't do that this week , '' Woods said . `` But I showed positive signs for the next time I play , which is a good thing . '' Woods ' round of 66 on Sunday was matched by his 22-year-old U.S. Ryder Cup teammate Rickie Fowler , who finished eighth to make it back-to-back top-10s in WGC events . Meanwhile , world No . 3 Luke Donald slipped out of contention with a closing round of 72 . The Englishman was seeking a second WGC title of the season after winning the match play event in February , but his challenge faded with bogeys at the 11th and 13th holes . Donald had to make do with seventh , with fellow Europeans Anders Hansen of Denmark and Italy 's Francesco Molinari in a tie for third .
