After what many consider the year's best day of tennis was curtailed by London showers, "Manic Monday" drifts into an unexpectedly tremendous Tuesday. Normally known as "Ladies" Day," the second Tuesday of the tournament is normally reserved for only the four Ladies" Singles quarterfinals. But five rain-postponed men's matches (three of which were in the second set, two of which had yet to begin at all). The men's matches, spread across five courts, are up first. The women's quarterfinals, divided evenly between Centre and No. 1 Court, will follow. Rain could again play a role in the day's matches, so expect to hear even more about the all-important Centre Court roof. The day's highest profile match, four-time Wimbledon champion Serena Williams vs. 2011 champion Petra Kvitova, is scheduled to be the second match on Centre Court. Coverage of the matches will appear here throughout the day.
