Will Rafael Nadal became first if he win French Open?

If Rafael Nadal wins the French Open, he would not automatically become the top-ranked player in the ATP rankings, as rankings depend on various factors including points from previous tournaments. However, his victory would add to his record of French Open titles, further solidifying his legacy as one of the greatest clay court players in tennis history. Whether he becomes the number one player would depend on the performance of other top players in the tournament and their current rankings.
