Baddeley shot a final-round 69 for 12-under-par total of 272. Singh shot a 69 for a 274 total. The victory for Baddeley, who last won in 2007 in Phoenix, was a combination of great ball striking and improved putting, which had been a weakness in the past. “These last few weeks have really been nice to start to put some scores on the board. This week has been really nice. I feel like I've played really well pretty much all week,” a smiling Baddeley said.

He raised his arms in victory on the 18th green at historic Riviera Country Club. It was his third career victory, the first his kids had been able to see in person and his first after reuniting with his original teacher from Australia. “It’s fun to be getting results from what I’ve been doing.”

After taking a one-shot lead going to the final 18 holes, Baddeley played so well and steady, he never gave the rest of his challenges, including Singh and two-time winner Fred Couples, a chance to take the lead. Kevin Na, the young American golf star, was alone in third place at 9-under-par after a birdie on 17 for a 275 total. Couples struggled with a final day 74. American Jimmy Walker was tied for fourth at 8-under-par 276 along with Australian Robert Allenby and American Ryan Moore.

Vijay Singh waits to play on the second tee during the fourth round of the Northern Trust Open.

After Singh made a 10-foot birdie putt on the par 5 16th hole to cut his deficit from three shots to two, Baddeley hooked his drive into the left rough on the 17th hole. But he played a beautiful recovery shot back into the far right side of the fairway to stop the Singh rally.
