(CNN) -- Martin Kaymer became the youngest winner of the Scottish Open after triumphing by two shots at Loch Lomond on Sunday.
Martin Kaymer has climbed up the Order of Merit after successive victories in Europe.
The 24-year-old German claimed his second title in successive outings on the European Tour as he headed off overnight leader Gonzalo Fernandez-Castano and France's Raphael Jacquelin.
Kaymer, who was the tour's rookie of the year in 2007, became the second player this season to win back-to-back after South Africa's Richard Sterne won twice on home soil in December.
He is now second to Paul Casey on the European Tour's money list after taking home $1.7 million in prizes in the past fortnight, and he is just outside the top 10 in the world heading into the British Open at Turnberry next week.
Kaymer, who clinched his fourth title, started the final round one stroke behind Fernandez-Castano and fell further adrift of the Spaniard with a bogey at the second hole.
But three birdies before the turn put him ahead going down the inward nine, and then his fifth of the round after a superb approach to the par-four 15th hole put him three shots clear.
Jacquelin charged up the leaderboard with four birdies in his last six holes to close with a five-under-par 66, but Kaymer could afford a bogey at 16 before parring his final two holes to end on 15-under 269 after a 69.
Fernandez-Castano, who won the British Masters in a play-off last September, dropped shots at the fourth and 13th holes, then picked up a stroke at 14 and parred his way home for a 72.
Australia's Adam Scott finished strongly with a 66 to share fourth place on 12-under with Denmark's Soren Hansen, who closed with 70.
South Africa's Retief Goosen had been tied for second with Kaymer going into the final round, but shot a disappointing 73 to share sixth place on 11-under with American golfer Nick Watney (67).
Lee Westwood, who charged up to equal sixth place on Saturday with a fine 64, had to settle for a share of eighth place with fellow Englishman Ross Fisher (67) on 10-under after ending with a level-par 71.
