Andy Murray and Sam Stosur were among the top names on show during a packed Wednesday schedule at the Citi Open.
The intensity is picking up on the ATP and WTA Tours with the U.S. Open now less than four weeks away.
And it appears Murray has plenty of work to do to be ready for the year's final slam after he became the day's biggest casualty, losing to Teymuraz Gabashvili.

The biggest upset of the day came when Gabashvili downed Murray, the No. 1 seed on the men's side of the bracket.
While Murray appeared to be in control midway through the third set after breaking Gabashvili, the Russian broke right back and assumed control in the match's decisive tiebreak.
"I normally back myself to return a little bit better than I did," Murray said after the loss, according to ATPWorldTour.com. "I think in the tie-break I don't think I put one return in the court when he was serving. I feel like I didn't do a good enough job of putting enough first serve points in the court."
Gabashvili credited his win to a new-found mental toughness: "I'm confident now and for sure this helped me in this match and also in the first round against Benjamin Becker, which was really difficult," he told ATPWorldTour.com. "I knew if I just played confident and try my weapons and let's see how it goes and it went to my side."
Another upset on the men's side saw Steve Johnson knock off No. 11 Bernard Tomic in three sets. This is the first time since the French Open that Johnson has won two matches in an ATP tournament.
Tennis reporter Christopher Beck had an interesting take on the way Tomic performed in the match after winning a difficult first set:
Tomic hasn't been doing much different this year, but it's shaping up to be his first season without a tournament win since 2012. His return game was off the mark, as Johnson beat him for 20 aces in the win.
Johnson has not made it past the third round in any tournament this season, so a win in his next match would be a huge confidence boost as he looks to move up the rankings.
There was no danger of an upset for John Isner, who just outmuscled Victor Estrella Burgos with 17 aces and won 37 of his 40 first-serve points. It was an excellent start to the tournament for the 30-year-old.
Isner is starting to find momentum, building off of his win at the Atlanta Open last week. He needed a drastic turnaround after losing in the third round at Wimbledon and first round at the Hall of Fame Tennis Championships.
It's been a long struggle for men's tennis in the United States, but at least Isner is showing signs of life. When his serve is working, good things are going to happen.
As the Washington Post's Ben Raby noted, Isner is one of two players who stands to benefit from Murray's early and uncharacteristic exit:
For the second consecutive day, Stosur made it through her match in straight sets. This time she knocked off Irina Falconi, though it was close in the second set with Stosur needing to win the last five games to do it.
As a prize for her victory, Stosur gets to take on Monica Niculescu in the next round. Niculescu had her own fight, losing the first set against Lauren Davis 6-1 before losing only five sets in the next two matches combined.
Davis' serve really hindered her performance, as she had six double-faults and no aces. Niculescu didn't dominate on the serve, having just three aces, but she did win 12 of 15 first-service games in the final set.
By comparison, Stosur had eight aces in her two-set victory Wednesday.
The biggest upset on the women's side came from unseeded American qualifier Louisa Chirico when she upended fifth-seeded Alize Cornet in three sets. This http://texastennisopen.com marks the first appearance in a WTA quarterfinal for the 19-year-old.
Per WTA Insider, Chirico has been making more waves than simply making it into the quarterfinals:
It's been a huge week for Chirico that will continue, but Cornet's loss continues an unfortunate pattern for the 25-year-old this season. She is actually under .500 with a 17-19 record in singles matches, causing her to drop to 27th in the world rankings.
Chirico's win and momentum this week could lead to bigger things in the future, given how young she is and how composed she's looked on the court.
All told, Wednesday was exactly what the Citi Open needed. The marquee players have all played at least one match now, with some big upsets occurring along the way and plenty of drama heading into the quarterfinals.
