Photo Gallery: Miami Open Moments, Wednesday, 3/30

During the second week of the Miami Open, we'll bring you exclusive photography from Anita Aguilar, who is covering the tournament for TENNIS.com. Steve Tignor provides the captions.

As always, Bethanie Mattek-Sands came dressed to play. She and doubles partner Lucie Safarova opened the day on the stadium.

Their opponents, Lucie Hradecka and Andrea Hlavackova—a.k.a, the Silent H's—shared a laugh...

While Mattek-Sands shared an idea—or a secret?—with Safarova.

In the end, the winners shared a hug.

One of these forearms is not like the others.

Johanna Konta making her signature move, the elegantly exaggerated pre-serve ball bounce. If she keeps rising up the rankings, will she start a trend?

Victoria Azarenka, in action against Konta, was even more intense than normal, which is saying something. She needed to be, because she wasn't hitting the ball that well in the wind to start.

Vika spent much of her day looking like this...

...and this...

...and this.

But she still won, 6-4, 6-2. Azarenka is now 20-1 on the year, and back in the Top 5.

Konta sent her ponytail into full flight with this forehand. Her quarterfinal run was another strong result.

Speaking of strong results, David Goffin beat Gilles Simon to reach his first Masters 1000 semifinal.

Simon showed us his teeth, but couldn't show his best tennis over the last two sets.

Here, he finally had enough of whatever his coach was trying to tell him.

But like many of his fellow ATPers, Simon remains a threat in his 30s.

The ever-impassive Goffin was excited enough by the win that even he cracked a semblance of a smile.

After a quarterfinal run at Indian Wells, he's getting used to signing the Masters lens.

Angelique Kerber leaped for a return in her win over Madison Keys.

Then she leaped again...

...and again. From up close, you can really appreciate her athleticism.

"It was a really bad night," Keys said. She made almost as many unforced errors (39) and she won points (43). But she and coach Jesse Levine still managed a smile.

Kerber had the last smile. She says she'll be ready for a highly anticipated semi with Azarenka tonight.

Novak Djokovic, in flexible form, was the evening's headliner.

His opponent, Tomas Berdych, made it interesting, but ultimately lost his 23rd match in 25 meetings with Djokovic.

This time Djokovic may have been a little too flexible...

...because he ended up tweaking his back.

But it didn't matter. Tomas didn't need to be told how this story ended.
