I.J. Jang carded a four-under 66 on Sunday to win The Crowns 2012 by two strokes.
Jang, who won for the second time on the Japan Golf Tour, finished at eight- under-par 272. He erased a two-stroke deficit in the final round.
He carded three birdies on the front nine to move to seven-under. After a birdie on the 12th, Jang tripped to a bogey on No. 13. He atoned for that mistake with a birdie at 16, then parred the final two holes to seal the win.
Third-round co-leaders Steven Conran and Yoshikazu Haku both managed even-par rounds of 70 to share second place at minus-six.
Prayad Marksaeng and Hideto Tanihara tied for fourth at four-under-par 276. They both closed with one-under 69s. S.K. Ho (67) was among five players tied for sixth at minus-three.
