The longest match in tennis history was played Wednesday — and it's not over yet.

John Isner and Nicolas Mahut were locked 59-59 in the fifth set in a 10-hour first-round match at Wimbledon when play was suspended because of darkness. The match time shattered the previous record of 6 hours, 33 minutes — set at the 2004 French Open between Fabrice Santoro and Arnaud Clement. Isner and Mahut's still unfinished fifth set alone stands at 7 hours, 6 minutes. It will resume Thursday at 3:30 p.m. local time (10:30 a.m./ET) at the earliest.
