HONOLULU — Zach Johnson closed with a 5-under 65 on Sunday for a two-shot victory in the Sony Open, ending his two-week stay in Hawaii by playing his final six rounds in 30-under par.

Johnson, whose 64-67 last weekend at Kapalua gave him a tie for sixth, outlasted David Toms in a well-played duel along the back nine of Waialae to build a two-shot lead, then eliminated any drama with a two-putt birdie on the 18th for the second victory in his last six starts.

Tadd Fujikawa, the 18-year-old from Honolulu trying to become the youngest winner in PGA Tour history, started the final round two shots out of the lead, but never got any closer as he struggled to a 73 and tied for 32nd.

"I just couldn’t get anything going," said Fujikawa, who resumes his senior year in high school today.

Johnson finished at 15-under 265 to earn his fifth career victory.

Toms, who won the Sony Open three years ago, had to settle for a strong start to his season. He finished out of the top 125 on the money list last year and is trying to qualify for the big events that for years were a regular part of his schedule.

Toms closed with a 66 and tied for second with Adam Scott, who gave himself a late chance with a 64.
