US Open Women's Semis an All-American Affair 

What a day for Team USA. 

The stage has been set for an American woman to raise that silver Tiffany trophy at the end of the fortnight in Flushing Meadows. 

On Day 10 of the US Open, wins by CoCo Vandeweghe and No. 15 seed Madison Keys pushed the last two Americans into an All-American final four, alongside compatriots Venus Williams and Sloane Stephens.  

Vendweghe led the charge on Wednesday, topping No. 1 seed Karolina Pliskova, 7-6, 6-3. Vandeweghe banged out forceful forehand after forceful forehand, and unleashed a 103 mph serve past Pliskova on second match point, securing her spot into her first-ever US Open semifinal – and her second of the year, in addition to the Australian Open.

"I always dreamed of being on the real big stage," said Vandeweghe, 25. "I couldn't wish for anything more." 

With her win, Vandweghe will rise to a new career-high ranking of at least No. 15 by the end of the tournament. 

Keys victory followed later that day under the bright lights of Arthur Ashe Stadium, defeating Estonia’s Kaia Kanepi in two tidy sets, 6-3, 6-3. 

Keys was in fine form, putting away 23 winners and eight aces to take the match in just over an hour. 

Four Americans in the semifinals is "pretty awesome," said Keys, post-match. 

Keys' win secured the first All-American semifinals since 1981, and guarantees the first All-American final since 2002, where Venus fell to sister Serena Williams. 

Day 11 will see the final four U.S. women take to the court and battle for the final spot. 

The action will kick off at 7 p.m. in Arthur Ashe Stadium, where Venus Williams will first face off against Stephens, followed by the Keys and Vandeweghe clash. 

Day 11 will also see Bob and Mike Bryan in the men’s doubles semifinals, where the No. 5 seeds will face the No. 11 seeds Feliciano Lopez and Marc Lopez.
