With her 6-4, 6-0 loss to Kim Clijsters in the fourth round Monday, defending Miami champion Victoria Azarenka will drop to No. 9 in the world rankings, behind Jelena Jankovic and Agnieszka Radwanska, and could drop farther, depending on the outcomes of later matches.

“It was a really bad game for me today,” Azarenka said. “I just wasn’t myself on the court and I need to work harder!”—M.C.
