(CNN) -- Top seed and world number one Serena Williams cruised into the second round of the Paris Indoor Open with a straight sets victory over Czech left-hander Iveta Benesova on Wednesday.
Williams had no problems in justifying her top seed status in the first round of the Paris Indoor Open.
Williams, who returned to the top of the women's world rankings after victory in last month's Australian Open, was too strong for her opponent -- winning 6-1 6-4 to set up a clash with Croatian qualifier Karolina Sprem.
Second seed Jelena Jankovic is also through, but she was made to fight by Francesca Schiavone of Italy before going through 7-5 7-6.
Meanwhile, home favorite Amelie Mauresmo, seeded eighth, enjoyed an element of revenge by crushing Italy's Sara Errani 6-2 6-0 in their first round meeting.
Errani beat the former world number one in straight sets on Sunday in the fourth match of Italy's 5-0 Fed Cup triumph over France, but Mauresmo secured early breaks in both sets en route to an emphatic win.
Sixth seed Patty Schnyder also booked her place in the second round with a 6-4 7-6 victory over Ukrainian Alona Bondarenko.
Elsewhere, former world number one Ana Ivanovic has hired Craig Kardon as her new coach after splitting from former mentor Sven Groeneveld.
Ivanovic has slipped to eighth in the world rankings after a dismal run of form and will be hoping 47-year-old Kardon -- who has worked with Martina Navratilova, Lindsay Davenport, Mary Pierce and Jennifer Capriati -- can steer her back to winning ways.
