Tuesday's weather: Cloudy and cool with sunny breaks. High of 70.
• Clijsters embarrasses Safina on center court. In 2009, Dinara Safina advanced to the Australian Open final before falling to Serena Williams. Two years later, she's going home without having won a single game. In Tuesday's first-round clash with Kim Clijsters, Safina became the first former No. 1 player to lose 6-0, 6-0 at a Grand Slam in Open Era history. The 24-year-old Russian, who advanced to the fourth round here in 2010, will drop out of the Top 100.
• Top seeds on cruise control. No. 1 Rafael Nadal, No. 4 Robin Soderling, No. 5 Andy Murray and No. 7 David Ferrer advanced on the men's side, with No. 2 Vera Zvonareva, No. 5 Sam Stosur and No. 7 Jelena Jankovic among the women's winners.
• Tsonga digs deep for victory. France's Jo-Wilfried Tsonga, a runner-up here in 2008, rallied from two sets down for a 4-6, 2-6, 6-2, 6-3, 6-4 victory over Philipp Petzschner of Germany. The 25-year-old Tsonga improved to 5-0 lifetime in five-set matches.
• Del Potro makes winning return. 2009 U.S. Open champion Juan Martin del Potro, who played just three matches in 2010 while plummeting to No. 258 in the rankings, won 7-6(13), 6-4, 6-4 over Israel's Dudi Sela. "It's nice to be here with these players and playing in a Grand Slam," Del Potro remarked afterward. "I met with all the players, especially the top 10 players. They supported me when I was very bad. So now I say thank you."

They Said It
"I didn't know how to win a point. There was nothing I could do to hurt her. I'm scratching my head thinking what the hell I am doing. I couldn't find the answer. Embarrassing."--Dinara Safina, still looking for clues after a 6-0, 6-0 loss to Kim Clijsters
