Day 9 Recap

Sharapova won two of her first three meetings with Williams. It's been all downhill since then, however, as the American quickly turned the tables and has now tallied 18 consecutive victories over one of the era's other top players.

That's a testament to how much better Williams is than the rest of the field when in top form. Sharapova is a player who can hit a lot of opponents off the court with her forehand. But the tournament's No. 1 seed completely overpowered her with 31 winners and 13 aces en route to the comfortable victory.

Afterward, the 21-time Grand Slam singles champion tried to explain why she's been so successful against such a dangerous foe, as noted by Christopher Clarey of the New York Times.

"I don't know, something about her game," Williams said. "I like the way she hits the ball. Plus, when I play her, I know automatically I have to step up my game. I think that makes me play better."

Radwanska presents a completely different kind of challenge. She finished her victory over Suarez Navarro with just 15 winners and one ace. Instead, she relies on a consistent all-court game, highlighted by strong defense, to wear down opponents and force them into mistakes.

A similar player—Roberta Vinci—ended Williams' run at the 2015 US Open last summer with the calendar Grand Slam on the line. There are times when the top-ranked player in the world can get sluggish with her movement, and that's when she ends up on upset alert.

That said, ESPN Stats and Info pointed out the lopsided nature of their previous encounters:

Djokovic rebounded from a lackluster outing, at least by his incredibly high standards, that forced him to go five sets against Gilles Simon to sweep aside Kei Nishikori in a convincing manner. It represented a far more typical outing for the top seed.

His ability to adapt to any opponent is what's made him so tough to beat over the past couple years. He failed to find his usual rhythm in the Simon match, but he got right back on track. He won 49 percent of the points while returning serve to keep constant pressure on Nishikori.

He also significantly cut down on his unforced errors, as highlighted by Jon Wertheim of Sports Illustrated, to keep himself out of trouble and punch his ticket to the semifinals:

Djokovic must still raise his level further as he prepares to face Federer. The No. 3 seed has dropped just one set en route to the penultimate round despite a tricky draw that featured Alexandr Dolgopolov in Round 2 and has only become more difficult from there.

Sometimes it's easy to forget Federer is 34 because he still plays with such effortless grace. The usual signs of wear and tear when a player has been on tour for that long are few and far between for him, which is a testament to his desire to remain among the best.

ESPN Tennis provided some key numbers as he prepares to face off with Djokovic once again:

Four more semifinal berths are available Wednesday. Angelique Kerber will battle Victoria Azarenka in a match that figures to have its fair share of twists and turns. Whichever player survives that clash will take on the winner of a surprising matchup between Johanna Konta and Shuai Zhang.

Andy Murray will look to join his "Big Five" counterparts, Djokovic and Federer, in the semis with a victory over David Ferrer. Finally, Milos Raonic and Gael Monfils figure to put on quite a show with several highlight-reel moments before a winner emerges.
