Pakistan fight back after batting collapse

Pakistan's fast bowlers have hit back to reduce Sri Lanka at 3-64 at stumps on day one of the second Test after the hosts had been dismissed for 191.

Pakistan won the toss and opted to bat but struggled against the pace of Lahiru Kumara and the spin of Lasith Embuldeniya.

The 22-year-old Kumara claimed 4-49 with his lively pace and left-arm spinner Embuldeniya justified his selection with 4-71 as Pakistan lost its last five wickets for only 19 runs.

"There's a small patch in the middle of the wicket so there's a small turn from that area," Embuldeniya said. "(It) will play a big role later in the game."

On a day dominated by pace with a tinge of grass on the wicket, Sri Lanka also ran into early trouble as it lost captain Dimuth Karunaratne (25), Oshada Fernando (4) and Kusal Mendis (13).

Fernando was caught behind off left-arm quick Shaheen Afridi. Mohammad Abbas (2-21) bowled Karunaratne and had Mendis caught low in the slips.

Angelo Mathews was 8 not out while nightwatchman Embuldeniya was unbeaten on 3 when bad light stopped play nine overs before the scheduled close.

Earlier, Asad Shafiq (63) and the ever-reliable Babar Azam (60), who made a century in the rain-hit drawn first Test, scored half centuries for Pakistan.

Left-arm fast bowler Vishwa Fernando had made early cracks into Pakistan's batting when he knocked back the off stumps of Shan Masood (5) and Azhar (0).

Azam - the only other batsman after India's Virat Kohli to be in the top 10 in Test, ODI and Twenty20 rankings - added 62 runs with Shafiq after Pakistan slipped to 65-3 in the first session.

Pakistan's latest batting hope, Abid Ali (38), hit seven fours, and a pulled six off captain Dimuth Karunaratne's occasional spin, before he was undone by Kumara's sharp delivery and was out lbw before lunch.

Abid added 55 runs with Azam before Kumara struck in his second spell.

Azam completed his half century off 75 balls with a cover-driven boundary in offspinner Dilruwan Perera's first over before Embuldeniya lured him for a big hit and got him stumped.

Haris Sohail, who struggled against Australia in the only Test he played, was given another opportunity, but the left-hander was trapped lbw by Embuldeniya in the last over before tea which Pakistan took at 5-171.

Kumara then ran through Pakistan's lower order after tea.
