Paceman Junaid Khan grabbed five wickets I and Bilawal Bhatti finished with three as Pakistan enjoyed the better of the opening day of the first Test against Sri Lanka in Abu Dhabi on Tuesday.

Junaid claimed his fourth five-wicket haul, taking figures of 5-58, while Bhatti took 3-65 in his first Test as Sri Lanka were bowled out for 204 after Misbahul Haq won the toss and opted to bowl first on a greenish Sheikh Zayed Stadium pitch.

By the close on the opening day Pakistan reached 46-1 with debutant opener Ahmed Shehzad not out on 25. Fellow opener Khurram Manzoor ran himself out after making 21, leaving Pakistan trailing by 158 runs but with nine first-innings wickets remaining.

Amidst the collapse in the Sri Lankan innings, skipper Angelo Mathews stood out, defying the Pakistan attack for 160 minutes for his 91.

He added an invaluable 61 for the ninth wicket with Shaminda Eranga (14) to lift Sri Lanka from a precarious 124-8.

Mathews hit 15 boundaries during his fighting knock, improving on his previous best of 64 not out against Pakistan at Colombo in 2009 before he was the last man

out, stumped off Saeed Ajmal, who finished with 2-32.

Misbahul Haq's decision to field first had looked unwise as Sri Lankan openers Dimuth Karunaratne (38) and Kaushal Silva (20) gave their team a sound start, putting on 57 for the first wicket.

But, from 66-1, Sri Lanka lost seven wickets for the addition of 101 runs in the afternoon session.

Bhatti, making his Test debut, took three wickets off just eight balls after lunch.

He had Silva caught at slip off the fourth ball after the resumption and then had the experienced Mahela Jayawardene (5) caught behind in his next over.

A ball earlier, Jayawardene had been caught behind only to see the umpire call it a no-ball.

Two balls later, Bhatti had Dinesh Chandimal caught in the slip by Mohammad Hafeez for a duck to leave Sri Lanka struggling at 76-4.
