Two 20-year-olds shone as Pakistan clinched a see-saw match at Sharjah to beat the West Indies 2-0 in the one-day series between the two sides.

All-rounder Shoaib Malik made his first century as they overcame a dismal start to post a competitive total.

Then Mohammad Sami stole his thunder with the 15th hat-trick in one-day history in figures of 4-44.

The 20-year-old made 111 not out, his second fifty coming off only 35 balls, after Pakistan had been reduced to 51 for four.

It was a marvellous effort by a player whose highest score in 20 previous one-day appearances was only 44.

Paceman Cameron Cuffy was the pick of the West Indies attack, taking 2-35 in his 10 overs.

Pakistan skipper Waqar Younis chose to bat first after winning the toss, but Inzamam-ul-Haq was caught in the slips off Cuffy and Shahid Afridi gave a return catch to Merv Dillon in the following over.

It left them on seven for two and the slump continued when Cuffy trapped Younis Khan lbw for 18 and Yousuf Youhana fell in similar fashion to Corey Collymore for one.

Malik and Naveed Latif began the recovery with a fifth wicket partnership of 73 before Naveed fell to West Indies skipper Carl Hooper for 45.

The recovery continued as Abdur Razzaq contributed 30 to a stand of 62 off 52 balls, but Malik did the bulk of the scoring thereafter before finally runnining out of partners with one over still to be bowled.

When the West Indies replied, Daren Ganga fell to the first ball of the innings, caught behind off Waqar.
