SAN FRANCISCO (AP) - Jay Don Blake won the Charles Schwab Championship on Sunday for his second victory of the season following a 20-year drought, while Tom Lehman took the season points title and $1 million annuity.

Blake closed with an even-par 71 for a two-stroke victory in the Champions Tour's season finale. He finished at 8-under 276 at TPC Harding Park.

Mark Calcavecchia (69), Loren Roberts (70), Michael Allen (71) and Jay Haas (71) tied for second.

Lehman shot a 72 to tie for 18th at 2 over, enough to hold off Calcavecchia by 74 points. Calcavecchia needed to finish no worse than a tie for second with one other player to have a chance to overtake Lehman.

Almost two months after surviving a five-hole playoff to win the Songdo Championship in South Korea for his first win since 1991, Blake calmly worked his way through the final round while a crowd of contenders took turns making brief runs at the lead.

Blake hit 12 of 14 fairways, made a pair of nice par saves out of the sand on the back nine then made the tournament-winning par on 18 after taking a bogey on the par-3 17th.

Nearly two dozen friends and family members rushed the green after Blake sank a short putt for par on the final hole. He earned $440,000 and finished fourth in the overall standings.

Blake, who had a four-shot lead with five holes to go and got some help from the contenders behind him.

Allen, second at this tournament in 2010, got to 7 under twice but couldn't capitalize. He birdied No. 16 but a bogey on 17 dropped him back.

David Frost, who shared the lead after two rounds, also got to 7 under before fading. Frost had a 72 and finished in sixth at 5 under.

With Blake cruising, the only drama surrounded the points title.

Lehman, a three-time winner this season, struggled most of the tournament and never had more than two birdies in a round. Playing several groups ahead of Calcavecchia, Lehman had to watch from near the 18th green until his title was secured.

Calcavecchia made Lehman sweat it out and hit a solid tee shot on 18 before pushing his approach far right. He two-putted for par, then watched his chances at passing Lehman end when Allen putted out for par, guaranteeing at least a three-way tie for second.

Two-time defending tournament champion John Cook (71) tied for 20th at 3 over.
