Novak Djokovic said he'd played "one of the longest games" in his life as he defeated Pablo Andujar to reach the quarter-finals of the Tel Aviv Open. Having won the first seven games, Djokovic found himself involved in a titanic tussle in the eighth, which included 11 deuces and five break points saved by Andujar before the Spaniard finally took his first game of the match.
