The French Open in the past few years have been the domain of the veterans. Since 2005, only 1 out of the 4 winners have been a first-time grand slam winner.
So this trend points to Ovechkina, Banaszek or Taliamanosoko victories.
I'll go with Larissa, seeing she's the only one - besides Marteena - who has won the French Open before and 2009 is all about former Grand Slam champions reclaiming their crown.
