London: American Marco Dawson fired a final round 64 to win the Senior Open at Sunningdale on Sunday and deny Scotland`s Colin Montgomerie a maiden victory in the tournament.
It was only the third career win for the 51-year-old, German-born Dawson who finished on 16-under, one shot ahead of German star, and last year`s winner, Bernhard Langer.
Montgomerie had held the lead on the final day only to slip three strokes adrift at the finish with a 67.
"Bernhard made a phenomenal par on the 16th and Colin made a phenomenal par at the 17th, and I thought `Wow, these guys aren`t going away, it`s going to be a little harder than I thought`. Dawson told Sky Sports.
"It was great to play with them to see how they play and how they react, and I thought, `They`re not doing anything different than I am.
"They`re hitting the same shots, making the same swings, making the same mistakes and making the same putts`, so I just made a few more putts."
