Former world No. 1 Andy Murray of Great Britain failed to take advantage of an early lead and lost 7-6 (3), 6-1 to fifth-seeded Andrey Rublev of Russia in the second round of the BNP Paribas Open on Friday in Indian Wells, Calif.
Murray had four set points on Rublev's serve at 4-5 in the opening set but couldn't convert. Rublev subsequently rolled through the tiebreaker and dominated the second set.
"He had a lot of chances in the first set and I was lucky to win. Had I lost it, it would have been really, really tough," Rublev said. "After the first set, I felt more confidence and I knew that it would be even tougher for Andy to keep up his consistency."
Sixth-seeded Alexander Zverev of Germany survived two tight sets to top Australia's Christopher O'Connell 6-4, 6-4.
Zverev got the only service break of the first set in the final game. The players exchanged breaks in the middle of the second set, and then Zverev again logged a break in the last game to wrap up the victory.
"For me, he is a very difficult opponent. He has a lot of shots that are uncomfortable for me," Zverev said. "I'm extremely happy to be in winning ways again. Definitely happy to win in two sets."
