Miguel Angel Jimenez clung on to win the Senior Open Championship by a single stroke to defending champion Bernhard Langer.
The Spaniard poured in a clutch par save at the famous 17th hole to keep hold of his lead and when Langer could not birdie the last, Jimenez was able to make the simplest of fours for the title.
Jimenez led by two entering the final round and was a flawless four-under for the day through 14, but a bogey at the 15th hole saw his lead reduced to one.
Langer, who birdied the same hole in the group ahead having earlier made a mistake at the 13th, was unable to leave himself a realistic birdie chance at the last as his title defence came up one short.
Back-to-back bogeys at the 12th and 13th holes derailed Kirk Triplett's threatening run but the early leader nonetheless shared second with Scott McCarron and Stephen Ames.
Colin Montgomerie got off to a promising start on Sunday but fell to 14th as Jimenez added a second major to the Regions Tradition title he won earlier in the year.
