PARIS, France - Sara Errani and Roberta Vinci are just the ninth pair of co-doubles No.1s in WTA rankings history. And when they take the court at the French Open, they will be just the seventh to compete at a Grand Slam together. Is that a good sign for their title defense? As you can see below, deep runs for co-No.1s are common, but only one such duo has taken the title.
