Top-ranked Serena Williams looks in a relaxed mood as she prepares to face former finalist Sara Errani in the French Open quarterfinals.
As they prepare to come out, Williams is wearing headphones and jogging up and down on the spot, while Errani has good reason to look pensive.
Williams, seeking to win her 20th Grand Slam title, leads the Italian 8-0 in career matches, with five of those on clay.
Errani, the 2012 runner-up, lost 6-0, 6-1 to Williams in the semifinals here two years ago.
