Dustin Johnson has won the AT&T Pebble Beach National Pro-Am after Monday&aposs final round was cancelled due to inclement weather. The final round of the event was first called off on Sunday as wind and rain lashed the course. Organisers hoped to get it in on Monday, but it became apparently early in the morning that the course was not in good enough condition. The weather proved beneficial to the 24-year-old Johnson, who claimed his second career PGA Tour title with an overall score of 15-under-par 201. Currently in just his second full year on the PGA Tour, Johnson joined Anthony Kim as the only players under 25 with two titles. Johnson picked up six shots in Saturday&aposs third round to overtake Retief Goosen. Johnson was two strokes off the lead entering the third round before surging past Goosen with a five-under-par 67 at Poppy Hills. Goosen fell from the lead after a 74 at Spyglass Hill. Australian Jason Day finished in a tie for 14th place at six-under. Johnson&aposs victory pushed him up to 45th in the world, knocking Aussie Richard Green down to 65th, and left him as first reserve for next week&aposs Accenture World Match Play in Arizona. The left-hander will come into the field, however, if Tiger Woods chooses to delay his comeback.
