(CNN)  -- John Isner of the United States and his French opponent Nicolas Mahut made tennis history at Wimbledon on Wednesday as they contested the longest grand slam singles match of all time -- and it is still to be finished. It was called off for the day due to bad light at 59 games all in the fifth and deciding set after 10 hours of action on Court 18 at the All England Club. During the marathon fifth set, the pair surpassed the previous record of six hours and 33 minutes set at the 2004 French Open, when Fabrice Santoro beat fellow Frenchman Arnaud Clement 6-4 6-3 6-7 3-6 16-14.
