PHOENIX (AP) — Phil Mickelson birdied three of the final holes Sunday to win the season-ending Charles Schwab Cup Championship, and Bernhard Langer held on to win his sixth PGA Tour Champions season points title. Mickelson shot a 6-under 65 at Phoenix Country Club, getting up-and-down from short of the par-5 18th for birdie to reach 19 under. He joined Jack Nicklaus as the only player to win four of his first six PGA Tour Champions starts. Langer, who battled back pain all weekend, labored through a 2-under 69. The 64-year-old German finished at 12 under and had to wait for Jim Furyk to see if he would win the Schwab Cup. Furyk shot 71 to tie for fifth.
