Serena Williams has spent most of her career matching — and often breaking — older sister Venus' records. After tying Venus for the most WTA Tour titles among active players, there's little left for her to equal.Except Olympic gold.Williams overcame a shaky start and two service breaks to beat lucky loser Coco Vandeweghe 7-5, 6-3 Sunday for her second straight Bank of the West Classic title in a final tuneup before the London Olympics, reports The Associated Press.Serena and Venus won gold in doubles in 2000 and 2008 and will go for a third again this year when play begins July 28 on Wimbledon's grass. While Venus took home gold in singles in 2000, Serena has never medaled on her own."It would mean a lot to me, but I can't lay all my hopes and dreams on just that," she said. "But it would mean a lot. I would like to try to get one."Sustaining the moment has been a big reason behind Williams' busy schedule.Eight days after winning Wimbledon, Williams saved a set point and won the final four games of the opening set. It was the 43rd WTA Tour championship of Williams' career, tying older sister Venus for the most among active players.Williams even summoned her father, Richard, all the way from Europe for her final two matches to soak in the moment.The first all-American WTA final on home soil in eight years was hardly a one-sided affair.
