Pakistan made significant inroads into West Indies batting by lunch on day one of the first Test, reducing the hosts to 71-4 in the 26 overs that were possible in the opening session.
Playing on a Sabina Park wicket with some grass on it, Pakistan bowlers exploited well, with debutant Mohammad Abbas removing Kraigg Brathwaite with his second ball of the match for a duck.
Mohammad Amir then bowled debutant Shimron Hetymer for 11 and Shai Hope for two in quick succession as West Indies slipped to 32-3. It soon became 53-4 when Wahab Riaz lured another debutant Vishaul Singh into lobbing a catch to backward square. He made nine.
Roston Chase joined opener Kieran Powell and the two carried West Indies to lunch without further loss. Powell is unbeaten on 33 (69 balls; 2x4s), while Chase is on 12 (2x4s).
