Younis Khan struck his third century in consecutive innings to see Pakistan tighten their grip at the end of day one of the second Test against Australia.
The 36-year-old notched twin hundreds in the first Test, which the Green Shirts convincingly won by 221 runs, while his third in a row has helped his side move to 276-2 in Abu Dhabi.
Pakistan had made steady progress in the day's opening sessions as they racked up 158 runs, which was soon added to by Khan's tally of 111 not out.
Azhar Ali struck a century of his own unscathed, ensuring that just Ahmed Shezhad and Mohammed Hafeez have fallen so far ahead of tomorrow's second day of play.
