Missing from the tournament are Roger Federer and Rafael Nadal who won the BNP Paribas Open last week.
Maria Sharapova who was also recently victorious at the BNP Paribas Open made an appearance at the players' party along with world no.1 Novak Djokovic, David Ferrer, Victoria Azarenka and Agnieszka Radwanska among others.
Maria Sharapova is aiming for a rare double at the Sony Open. Only two players in WTA history have won back-to-back Indian Wells and Key Biscayne titles: Steffi Graf (1994 and 1996) and Kim Clijsters (2005).
If you bet on sports you might want to follow the tournament closely.
Djokovic will try to claim his fourth Miami title in Key Biscayne while Serena Williams attempts to take her sixth career crown at the $8.5 million ATP and WTA event that began since Tuesday. First-round byes are given to seeded players.
Meanwhile, Victoria Azarenka is still dealing with a nagging, painful injury to her right ankle. After withdrew from Indian Wells last week, Azarenka will enter the Sony Open without a loss. However it is still unsure whether she'll be able to play her first tournament match on Friday.
Another notable player to watch is Spaniard David Ferrer who drew strong contender Del Potro in his quarter at the Sony Open. After a spectacular start to the 2013 season, Ferrer suffered a crushing defeat at the hands of Nadal in the finals of Acapulco. That seemed to drag his disappointment with him to Indian Wells. With Del Potro in his half, it could be extremely hard for Ferrer to regain back his no.4 ranking from Nadal.
Looks like the tournament will not lose its shine without Nadal and Federer.
