Johnson shares lead at Pebble Beach

PEBBLE BEACH, Calif. — Dustin Johnson overcame a sloppy back nine by making a 10-foot birdie on the 18th hole at Pebble Beach for a 2-under 70 that gave him a share of the lead going into the final round of the AT&T Pebble Beach National Pro-Am.

Ted Potter Jr. needed to birdie one of his final three holes for a 59 at Monterey Peninsula. He finished par-bogey-bogey for a 62 and was tied with Johnson.

They were at 14-under 201.

Jason Day, coming off a victory two weeks ago at Torrey Pines, shot a 69 at Pebble Beach and was two shots behind.

Johnson is going for his second straight PGA Tour win as he closes in on a full year at No. 1 in the world.

PGA TOUR CHAMPIONS: Mark Calcavecchia birdied the last three holes to take a two-stroke lead over Bernhard Langer into the final round of the Boca Raton Championship.

Calcavecchia shot a 6under 66 at The Old Course at Broken Sound, rebounding from bogeys on Nos. 14 and 15 with the late birdie run. He made a 25-footer on the par-4 17th and set up a 3-foot putt on the par-5 18th with a chip after leaving an approach from the right pine straw to the right of the green.

Langer, the 2010 winner in his home event, had his second straight 66. The 60-year-old German star won seven times last season, three of the victories majors.

The 57-year-old Calcavecchia had a 14-under 130 total. He opened with a 64 for a one-stroke lead in the senior tour’s first full-field event of the season.

Bart Bryant had a 64 to match Jerry Smith (67) at 10 under. Paul Broadhurst (66), Steve Flesch (68) and Michael Allen (68) were 9 under. John Daly followed an opening 67 with a 73 to drop to 4 under. Defending champion Scott McCarron was 2 under after a 69.

PERTH SUPER 6: Thailand’s Prom Meesawat took a two-stroke lead after three rounds with a 5-under 67 while Lee Westwood went from a tie for first place to being out of the tournament.

The Thai golfer had a three-round total of 12under 204 at Lake Karrinyup Country Club, with three golfers tied for second: American Sean Crocker (67), Australian Lucas Herbert (69) and Denmark’s Thorbjorn Olesen (69).
