Isner is marathon man again in 46-point tiebreak at Dallas Open
John Isner and Reilly Opelka played out a marathon 46-point tiebreak, the longest in ATP Tour history, at the Dallas Open on Saturday as Opelka edged out his fellow American 7-6(7), 7-6(22) to reach the final. Isner was involved in the longest match of all time against Frenchman Nicolas Mahut in the first round of Wimbledon in 2010. The pair battled it for 11 hours five minutes across three days before Isner took the fifth set 70-68.
