Shadab Khan delivered his second match-winning performance on the trot as Pakistan secured a three-run win over the West Indies in the second T20I on Thursday.

After an impressive T20I debut in the first match where he took three wickets for just seven runs, the leg-break bowler scalped four wickets for 14 runs -- including his first international wicket maiden -- to help the visitors defend a modest total of 132 in Trinidad.

The 18-year old -- who was added to a 31-member preliminary squad for the tour after Mickey Arthur met him during a three-day camp in Lahore on March 11 and then fast-tracked into the side -- conceded six runs in his first over, the sixth of West Indies' innings, but came back strongly and bowled his copyright googly, a delivery he used to dismiss two batsmen in the previous game, as he had opener Chadwick Walton bowled.

He went one better in the next over by taking two wickets. He first deceived Kieron Pollard, who charged down the wicket and was left stranded as the ball spun away, leaving wicketkeeper-captain Sarfraz Ahmed with a simple task, and then bowled Rovman Powell with the very next delivery, another leg-break.

With the hosts on 81 for five and with a good chance of making it to the target, Shadab bowled an incredible over, conceding no runs and having Marlon Samuels caught behind. There would be little reward for guessing that he did so with one of those patented googlies.

"He's [Shadab] bowled very well, but I think we've gifted him a few wickets. We just need to be a bit more ruthless against him and see what transpires," West Indies coach Stuart Law said.
