Rain halted play on the second morning of the second Test on Tuesday in Colombo but Pakistan kept up their charge to move into a 12-run lead against Sri Lanka.
The tourists were 178-2 after resuming under gloomy skies on 145-2 with Abdullah Shafique, on 87, and skipper Babar Azam, on 28, batting in a stand of 57.
Only 43 minutes of play was possible before the downpour began and forced officials to call lunch.
Shafique and Azam took on the Sri Lankan bowlers with a string of boundaries after a couple of maiden overs to push for a big lead in response to Sri Lanka’s first-innings total of 166.
Pakistan, who lead the two-match series 1-0, dismissed Sri Lanka in the second session on the opening day after the hosts elected to bat first.
Shafique put on a second-wicket stand of 108 with Shan Masood, who made 51, to put Sri Lanka on the back foot with their attacking play.
