( CNN ) -- American Bill Haas claimed a one-shot victory in the Bob Hope Classic on the final hole to join his father as a winner of the tournament . The 27-year-old went into the final day in California a stroke behind the lead but was able to break clear of the pack with a flawless 64 to finish on 30 under par . Tim Clark , Matt Kuchar and Bubba Watson all finished tied for second place on 29 under . Haas led by two strokes after an fine start but the chasing pack reduced his lead and a birdie on 17 put him level with leaders Clark and Kuchar . He completed victory with a birdie four at the last hole after he struck a brave tee shot . Haas fired his approach at the last to within 27 feet and two putts were enough to seal a victory that matches the win his father - Jay Haas - secured at the same event in 1988 . Haas , who was watched by his father , admitted the victory was even sweeter with a large family contingent present . `` It 's pretty special as I did n't know my dad was here . My dad and my brother and his uncle were there , '' Haas told the tournament 's official Web site . `` They knew they flew back from Hawaii last night , I thought maybe if I was in contention they might show up , but did n't see them until the end there . `` It 's not easy to win . I was so nervous coming down the stretch . I still do n't know how I hit the shot on 18 - my hands were shaking . ''
