Mauresmo's poor form has seen her drop out of the world top 20 this year
Former world number one Amelie Mauresmo reached the second round of the Kremlin Cup with a tricky 6-7 (3-7) 6-3 6-4 win over fellow Frenchwoman Alize Cornet.
Mauresmo was trailing 4-3 in the final set but won the last three games, securing her first win since reaching the fourth round of the US Open.
The unseeded 29-year-old now faces Russian second seed Dinara Safina.
Top four seeds Jelena Jankovic, Safina, Elena Dementieva and Ana Ivanovic received byes into the second round.
Both Mauresmo and Cornet struggled to hold their serve on the fast indoor surface of the Olympic sports complex in Moscow, but it was Mauresmo, who has dropped out of the world's top 20, had the edge in the decider.
Following her win, Mauresmo played down her chances against Safina.
"Dinara is in great shape and she obviously is the favourite in our match," said the former Wimbledon and Australian Open champion.
Another French contender, former Wimbledon finalist Marion Bartoli, had to retire against unseeded Slovak Dominika Cibulkova with a toe injury.
Cibulkova, who was leading 6-1 4-1, now plays Serbian fourth seed Ivanovic, while Russia's Vera Dushevina put out Czech Nicole Vaidisova 6-1 3-6 6-3 to set up a clash with top seed Jankovic.
The women's field is the strongest in the Kremlin Cup's 19-year history, with eight of the world's top 10 players taking part.
Only world number two Serena Williams and number six Maria Sharapova are absent because of injury.
In the men's event, Russian second seed Igor Andreev, who won in Moscow in 2005, went through when Lu Yen-Hsun of Taiwan retired with an ankle injury after losing the first set 6-2.
