The longest match in professional tennis history will resume for the third day of play between John Isner and Nicolas Mahut at Wimbledon Thursday.Isner and Manut have played 163 games so far and are tied at 59-59. Play was suspended Wednesday more than seven hours into the fifth set, when Mahut told the umpire that he could no longer see. Neither Isner not Mahut were well-known before the match, with Isner seeded 23rd and Mahut unseeded. The scoreboard broke and had to be turned off during the marathon session. The previous record was 6 hours and 31 minutes. Isner and Mahut begin their 10th hour Thursday afternoon. Earlier in the day, Queen Elizabeth II arrived at the tournament, her first visit in 33 years.
