The 2012 Sony Ericsson Open continues play on Tuesday in Miami. The tournament has already seen thrilling performances by Venus and Serena Williams and the continued dominance of No. 1 women's player Victoria Azarenka.
Tuesday marks Day 9 of the event. The day's action will feature the fourth round of men's singles play, as well as the women's singles quarterfinals. Maria Sharapova will join the Williams sisters and Azarenka as the notable names remaining in the competition. If Azarenka succeeds in defending her title at the event, it will mark her 29th straight win to begin the year.
The men's fourth round matches will not be lacking at all in star power. Novak Djokovic, Rafael Nadal and Andy Murray will all be in competition as they hope to advance to the quarterfinals on Wednesday.
