The biggest storyline going into the Miami Open was who was not playing instead of who was scheduled to take the court.

Serena Williams pulled out of the tournament Sunday because of oral surgery, which meant she joined the likes of Novak Djokovic, Rafael Nadal and Roger Federer on the men's side.

Even though Williams wasn't in the tournament, there were still a number of Americans in the field.

Querrey didn't last long, though, losing in straight sets to Yen-Hsun Lu. The serve let him down, as he finished with six double-faults and landed just 45 percent of his first serves in bounds. He also failed to convert either of the break points he created as he fell behind and never bounced back.

It looked as if Stephens were going to lose in straight sets as well when she dropped the first set to Oceane Dodin in a tiebreaker and fell behind in the second.

However, Stephens rallied to even the match at a set apiece and kept that momentum while steamrolling Dodin in the third set. Dodin finished with seven double-faults and won just 39.6 percent of her second-service points while failing to parlay her early lead into a victory with overall service troubles.

On the men's side, Tiafoe also prevailed with a comeback after dropping the first set.
