(Reuters) - Andy Murray saved seven match-points in a 31-minute tiebreak that stretched to 38 points before he finally subdued Germany's Philipp Kohlschreiber 6-7(4) 7-6(18) 6-1 to reach the Dubai Championships semi-finals on Thursday. The Briton finally bagged the second set tiebreak on his eighth set point to level the match. The ATP said no men's tour-level match has featured a tiebreak with more than 38 points since 1991 - six have finished 20-18. With no end to the tiebreak in sight, Murray, Kohlschreiber and the umpire were left confused as the players forgot to change ends when they were locked at 15-15. Tennis rules state players have to change ends every six points during a tiebreak.
