How best to summarize the action at the Sony Open through the early rounds? Rafael Nadal has been dashing, Maria Sharapova has been hot, and the Americans haven't had an easy one.

As we enter the business end of the tournament, here's a look back at some of our favorite photos from the early rounds in Miami.

 Venus Williams: Her tennis wasn't as sharp as it was last month when she won the Dubai Championships, but once again, Venus put on a clinic on how to compete and leave no doubt in anyone's mind that you gave 100 percent on court. (Clive Brunskill/Getty Images)

 Madison Keys: Being in the shadow of Sloane Stephens has its advantages. While the attention is on Stephens, Keys has been able to plug away quietly. (Al Bello/Getty Images)

 Ryan Harrison: The draw opened up and Harrison couldn't take advantage. The frustration was understandable. (Al Bello/Getty Images)

Grigor Dimitrov:  It was a focused but overall disappointing few weeks for Dimitrov after his big win at the Mexican Open. (Clive Brunskill/Getty Images)

Sloane Stephens: That look during her 6-0, 6-1 loss to Caroline Wozniacki said it all. (Matthew Stockman/Getty Images)

Rafael Nadal: Everyone loves towels! (Matthew Stockman/Getty Images)

Serena Williams: Bending but not breaking. (Clive Brunskill/Getty Images)

Nadal: You can blame that sweat on the humidity, not the opposition. He's lost just nine games in six sets so far. (Al Bello/Getty Images)

Agnieszka Radwanska: The shot never gets old but that colorful knee tape is certainly new. (Joel Auerbach/AP)
