Pakistan's new captain Younis Khan was on course for a fabulous double century on Tuesday as he guided the home team towards safety on day four of the first Test against Sri Lanka.

Younis was unbeaten on 178 with Faisal Iqbal yet to open his account as the home team reached 358-4 by lunch in reply to the tourists' 644-7 declared, just 87 runs from avoiding the follow-on.
