WIMBLEDON, England -- Aryna Sabalenka is one win away from ending Iga Swiatek’s 67-week run as the Hologic WTA Tour’s No.1-ranked player.

After defeating No.25seed Madison Keys 6-2, 6-4 on Wednesday in the Wimbledon quarterfinals, Sabalenka will need to defeat No.6 Ons Jabeur, who knocked off defending champion Elena Rybakina in three sets. 

What motivates Sabalenka more -- the chance for her first Wimbledon title, or the No.1 ranking?

“To be honest,” Sabalenka told reporters, “I want both. But I’m trying to focus on myself because I know if I start thinking about all this stuff, I’m going to lose my focus on court, my game.

“Later on we'll see if I’m ready to become World No. 1, or if I’m ready to play another final."

Sabalenka is the only woman to reach at least the semifinals of the past four Grand Slams. The reigning Australian Open champion has won 17 of 18 matches at this year’s majors, equaling Serena Williams’ feat of 2015.

Her match against Keys was the expected slugfest. Sabalenka, in particular, was going after everything -- especially second serves. For the match, 62 rallies were shorter than four shots. The average rally: 2.78 shots.

Sabalenka hit 17 winners and suffered only 14 unforced errors. Keys was 19 and 22.

Keys entered the match with a flawless 9-0 record this year on grass, going back to her second title at Eastbourne. This was the 28-year-old American’s second quarterfinal here, but Wimbledon remains the only major she hasn’t advanced to the semifinals.

The first game was a six-minute odyssey. Keys saved three break points, but not the fourth as Sabalenka sent a backhand slice winner knifing off the court.

Sabalenka broke a second time to take a 4-1 lead. But serving for the set at 5-2, Sabalenka encountered some resistance, especially from Keys’ backhand. Ultimately, Sabalenka closed out the first set, converting her third set point with a 100 mph serve Keys couldn’t handle.

The second set sailed along smoothly until the sixth game. That’s when Keys dug in and scored her first break. Two powerful service return winners set the tone and when Sabalenka’s looping forehand drifted just wide, Keys appeared to be in a commanding position at 4-2.

One game later, however, they were back on serve. Sabalenka broke through when a Keys backhand flew wide.

Sabalenka won her third game in a row, breaking Keys for the fourth time in the match and served for the victory at 5-4, winning her fourth straight game. Sabalenka has shown a closer’s instinct at these Championships. She won the last eight games in the fourth round against Ekaterina Alexandrova.

Sabalenka has now reached 40 match-wins for the year, behind only Swiatek. 

This run is particularly meaningful to Sabalenka considering she was unable to play a year ago. 

“I was really sad, but at the same time I was thinking that, 'OK, it’s a good time to kind of like reset and start everything over again,"' she said. "I was struggling a lot with my serve, with these emotions, with a lot of stuff. I just took that time as a good preparation, as a good little switch.

“I did really good work, and it helped me at the US Open. Then I started believing in myself more, I start playing better, I start feeling better on court. Emotionally, I start feeling better. I think this period gave me so much belief in myself.”
