Phil Mickelson drives from the ninth tee in Saturday's third round of the PGA Colonial golf tournament.

FORT WORTH, Texas — The frustration was evident on Phil Mickelson's face during a slow start in the third round of the Crowne Plaza Invitational.

Lefty was feeling a lot better — and still in the lead alone — when he finished the third round Saturday with a 17-foot birdie putt from the front edge.

"A nice way to finish the round," Mickelson said.

Mickelson overcame an early bogey and some missed chances with seven birdies in his last 13 holes for a 5-under 65 that got him to 12-under 198. He led Rod Pampling (63) and Stephen Ames (64) by one stroke.

Pampling was on pace for a record-tying round at Colonial, the course near the Australian native's Flower Mound home that he gets to play often. But he had consecutive bogeys at 16 and 17 before hitting his approach at No. 18 within a foot for a birdie that left him two strokes off the tournament record.

Ames started with three birdies in the first four holes and finished without a bogey.

Tim Clark (64) was alone in fourth, three strokes back. Ben Crane (67), Kevin Sutherland (68) and Brian Gay (69) were at 203.

This is the 27th time Mickelson will lead going into the final round of a tournament and this time he will be going for his second plaid jacket at Colonial. He has gone on to win 19 times, including the Northern Trust Open in February, his only victory this season.

The last six Colonial champions led or were tied for the lead after 54 holes. The last time that didn't happen was 2001, when then-defending champion Mickelson and Brett Quigley were tied going into the final round before Sergio Garcia won.

LPGA CORNING CLASSIC: At Corning, N.Y., even with an arthritic right wrist that hampers her swing, Jeong Jang is a player to be reckoned with. Jang, fresh from two straight top-3 finishes that moved her to fifth on the 2008 LPGA money list, shot a 3-under 69 Saturday to tie Erica Blasberg for the lead after three rounds at the Corning Classic. Playing with a bandage that conceals a painful cyst, Jang sank a 3-foot birdie putt on her final hole to tie Blasberg (70) at 7-under 209. The top two were one shot ahead of Leta Lindley (70) and Katherine Hull (72). Song-Hee Kim (70) was another stroke behind in fifth, and Mi Hyun Kim (68) was in a tie for sixth with Sung Ah Yim (70), Seo-Jae Lee (71), Sun Young Yoo (71), and Meredith Duncan (71). Dina Ammaccapane began the day with a one-shot lead but shot 76 and was five shots behind.

SENIOR PGA CHAMPIONSHIP: At Rochester, N.Y., steady Bernhard Langer held off Jay Haas' late run, which included a stunning eagle on Oak Hill Country Club's No. 17, and took a one-shot lead after the third round of the Senior PGA Championship on Saturday. Langer, the Champions Tour money leader, finished with an even-par 70 to put him at 2-over 212 for the tournament. Scott Simpson and Bill Britton were tied at 216 and Greg Norman was part of a four-man group at 217.
