Photo Gallery: Miami Open Moments, Friday, 4/1

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.

David Goffin was pushed to the limit, and beyond, by Novak Djokovic on Friday.​

This match never turned into a full-fledged death march...​

But it came close at times. Fortunately for Djokovic, he closed it out in two sets, 7-6 (5), 6-4.

"You have to hit the shot. You have to make every point," Goffin said about playing Djokovic. If you let down "for a few seconds," you're lost.​

That's pretty much what happened to the Belgian in the first-set tiebreaker.​

Djokovic stole that breaker by winning two highlight-reel points at the end. "I was in the right place at the right time," he said.

Or was he there because he can fly?

Blocking out the sun wasn't easy.

Djokovic's temper flared after he was called for a time warning. In the end, it helped him: He played with irritated aggression in the next game and broke serve.

The Serbian fans, and a passing bird, appeared to approve.

Nick Kyrgios was the night-session headliner. While he didn't win...

...he gave a packed house plenty of examples of his vaulting athleticism.

Kyrgios dared his coaching team to tell him something useful.

Could Kyrgios play the game from five feet off the ground? He might like the sport more if he could.

Back down on Earth, though, he was soundly beaten by Kei Nishikori.

Nishikori served well to start and dominated from the baseline. "He's always so aggressive against me," Kyrgios said.

Here, Kei gets a little air of his own.

The fans may have come for the Kyrgios show, but it was Nishikori, who reached his second Masters 1000 final, who put on a memorable display of tennis.​
