WATCH: Mohammad Amir's brilliant knock in second innings of Australia-Pakistan Test

Brisbane: Mohammad Amir played a crucial knock for Pakistan in second innings of the first Test against Australia at the Gabba which the visitors ended up losing by 39 runs.

While Amir was new at the crease, Aussie speedster Mitchell Starc troubled him with some quick pace as the left-handed batsmen also took some blows on his body.

When Amir was batting on 10, two of Starc's deliveries hit him on the body. Starc also sledged the bowler to put him under pressure.

Amir, in the first year of his return to international cricket following a five-year ban for spot-fixing, refused to buckle as he hit his highest Test score in a stubborn 92-run seventh-wicket partnership with Asad Shafiq.

The 24-year-old played some quality strokes during his 48-run knock, which included boundaries against Starc as well.

Watch Amir's fighting knock:

Despite a brilliant century by Shafiq, Pakistan fell short of the target by 39 runs on the final day of the opening Test.
