When and Where: Saturday's play from Miami gets underway at 11 a.m. ET. A live stream will be available of the whole day's play, including the evening session, via ESPN3. You can also access a live stream through the tournament Web site, via a subscription to Tennis TV.

Tournament Update: The Sony Ericsson Open has long been seen as one of the most prestigious events on the tennis calendar, a fact borne out by its billing as the sport's fifth major.

Just like in Indian Wells last week, the tournament features both the ATP and WTA tours, with all the world's top players involved.

And the event has already witnessed some memorable moments this year.

Fernando Gonzalez bowed out of professional tennis on the opening night following a defeat to Nicolas Mahut. After which a video tribute was played on court from some of the world's top players, illustrating what a popular competitor the Chilean was on tour.

There was even more emotion on show as Alisa Kleybanova made a miraculous comeback after a 10 month layoff following her diagnosis with Hodgkin's lymphoma. Although she has since exited the tournament, her first-round victory will surely go down as tennis' inspirational moment of the year.

Preview: Arguably the stand-out match on the men's side on Saturday sees Roger Federer go up against highly-rated young American Ryan Harrison.

After a first-round bye, Federer will be competing his first match in Miami since playing superbly to claim the title in Indian Wells last week. The highlight of Federer's run being a straight-sets semi-final win over his long-time rival Rafael Nadal.

Federer will have to avoid any hangover form last week, though, against the emerging Harrison. Still only 19, the Louisiana-native has been talked about as a future top-10 player and is already a threat on his day.

The other match to look out for in the men's draw features Novak Djokovic taking on Marcos Baghdatis.

After the disappointment of losing to John Isner in Indian Wells, the World No. 1 will be eager to reassert his dominance in the men's game by taking home the title in Miami.

While Baghdatis has struggled to live up to the expectations resulting from his run to the Australian Open final in 2006, the popular Cypriot is always entertaining to watch.

The play gets underway on Saturday with Serena Williams in action against 21st seed Roberta Vinci.

Serena did not show any signs of rustiness in quickly disposing of Zhang Shuai in her opening round and will be looking to add to her already joint-record tally of five Miami titles--currently shared with Steffi Graf.

Another intriguing match on the women's side sees an all-Belgium battle between Kim Clijsters and Yanina Wickmayer.

Clijsters is playing in her first tournament since a semi-final defeat to Victoria Azarenka at the Australian Open and will be keen to show that she is still a forced to be reckoned with at the top of the women's game.

Finally, it will be fascinating to assess how 19-year-old American Sloane Stephens fairs against world No. 2 and runner-up in Indian Wells last week Maria Sharapova.
