Keys overcomes Vandeweghe in all-American Stanford final

Madison Keys outdueled fellow American CoCo Vandeweghe 7-6(4) 6-4 on Sunday to win the Stanford Classic and capture her first title of the year.

In an evenly matched contest between two friendly opponents, third seed Keys was impregnable on serve but claimed the only break in the second set before closing out a confidence-boosting win ahead of the U.S. Open.

“It hasn’t been the easiest season, but it finally feels like I’m on the right track and feeling good about my tennis again,” Keys told reporters. “It feels amazing to have a title at home and on hard courts. I’m really, really happy that this is kind of the start of my US Open Series.”

Alexander Zverev issued a warning to top ATP rivals Sunday after winning the Citi Open for his fourth title of the year.

The 20-year-old German defeated South Africa’s Kevin Anderson 6-4, 6-4 to take top prize at the US Open tuneup event on the Washington hardcourts.

“I improved a lot in the last few months to get where I can win tournaments,” Zverev said. “The longer the tournament goes for me the better I’m able to play. Hopefully this can continue to be like that.” Russian Ekaterina Makarova turned on the marathon magic again to defeat Julia Goerges 3-6 7-6(2) 6-0 and win the Citi Open in Washington DC on Sunday. Seventh seed Makarova came from a set behind for the third successive time to claim her first WTA title in more than three years.

“Every time when I was coming back, I was really enjoying (it) and dreaming to win this tournament and here it is,” Makarova told reporters. “I don’t have a coach this week with me but I have some great supporters. The crowd was just amazing and I heard a lot of

Russians today. ”
