John Isner has sealed a spot in the second round of the Madrid Open with a 7-6[2] 6-4 victory over Adrian Mannarino.
Both competitors failed to create a break point in the first set, meaning that a tie-break was needed to separate the pair.
After snatching serve twice in the tie-break, Isner headed into the second set with the lead, but he once again struggled to break Mannarino down.
The match look destined for another tie-break, but Isner earned a crucial break, which was enough to win the second set and earn a place in the next round.
