Disappointing ending for Madison Keys

— -- LONDON -- A strained abductor muscle prevented Madison Keys from extending a seven-match win streak that included one grass-court title. But the 19-year-old American, who had to withdraw from Wimbledon on Monday before resuming her suspended third-round match, is just one McDonald's sweet tea from feeling much better.

She was one of five American women to reach the third round and, technically, the last to depart. This is the first time in the Open era no U.S. woman reached the fourth round at Wimbledon -- and the first time in any Slam since the 2011 French Open.

Keys, who was trying to level her match with Yaroslava Shvedova -- Shvedova was winning 7-6 (7), 6-6 when darkness intervened Saturday -- said the injury is not serious and she will be able to resume the US Open series schedule after about two weeks of treatment.

She will next play in Washington, where she will try to continue the momentum that included a singles grass-court title two weeks ago in Eastbourne, a result that saw her ranking rise to a career-high No. 30.

"I was trying not to bawl my eyes out," Keys said of leaving the court the other night. "I think there were some tears. I mean, it's definitely not how I want to be leaving Wimbledon, but it happens. [I] just have to take it in stride, just accept it, just try to get better."

Returning home to Florida after two months in Europe, Keys said she already knows the first thing she'll do.

"I think I'm going to have to stop by McDonald's and get a large sweet tea," she said. "It's the biggest thing I miss when I'm here. I visit so much, I know it's exactly $1.06 for a large sweet tea."

Perhaps a future endorsement deal could be in the works for a player whose career has taken a large jump over the past two weeks with victories over No. 7 Angelique Kerber and No. 8 Jelena Jankovic in Eastbourne.

"I don't think I need a McDonald's contract," Keys said. "If I could have a lifetime supply of sweet tea though, I'd be happy."

Bouchard leads the way

Eugenie Bouchard is proving to be no fluke.

The 20-year-old Canadian is through to the quarterfinals of her third major of the year with a 7-6 (5), 7-5 win over Alize Cornet

That gave Bouchard the most 2014 Grand Slam match wins of any woman -- 14 -- one more than Maria Sharapova, who was playing later, and Simona Halep, scheduled to be in action Tuesday. How far and how fast has Bouchard come? Last year she won a total of four matches in majors.

Bouchard is the first Canadian man or woman to reach a Wimbledon quarterfinal in the Open era. Last year, as a teenager, she beat Ana Ivanovic here.

It was worth noting that Bouchard won exactly one more point than Cornet (77-76), but was the better player in the crucial moments. Cornet was serving for the second set at 5-4, but Bouchard won 10 of the last 13 points.

"I've been in situations like that before," Bouchard explained, "so I had full belief and confidence in myself that I wasn't out. The second set wasn't over yet. I just tried to focus on my serve at 5-3. I played some good points at 5-4.

"I think basically I was able to step up on the important moments."

Etc.

Seven years ago, when Lucie Safarova reached the quarterfinals of the Australian Open, she was a 19-year-old with what looked to be a promising career ahead of her. As it turned out, she failed to do as well in her next 29 Grand Slam events. But the 30th was the charm: Safarova defeated fellow Czech Tereza Smitkova 6-0, 6-2 to reach her second major quarterfinal, where she'll play the No. 22 Ekaterina Makarova, who crushed No. 4 seed Agnieszka Radwanska in 6-3, 6-0. Safarova won 54 of 80 points and was credited with only four unforced errors.
